Opis:

The authors present the history of chrysoprase discovery and the progress of knowledge about this material over the millennia, based on the extended review of world literature. Tracing the oldest archaeological artifacts from before 9,000 years, the lens of history turns on a stone that has not been properly identified mineralogically for centuries. In the 1830s, chrysoprase was finally included into the chalcedony group and its green color was associated, very correctly, with nickel compounds dispersed in its structure. After all, the most current mineralogy of chrysoprase is presented on the basis of the results of modern analytical studies. These data clearly indicate that chrysoprase is a mixture of several SiO2 polymorphs with varying degrees of structural order (opal, chalcedony, moganite, quartz). This radically changes the previous taxonomy of chrysoprase and its position in current mineralogical and petrographic systematics.

Opis:

Kosovo lead and zinc ore deposits are located in the Trepca Belt which extends for over 80 km. Several ore deposits occur in that belt, with the most important - Stan Terg (Trepca). Stan Terg deposit originating at the contact between volcanic breccias and carbonate rocks. Two different types of mineralization can be distinguished. The older one has origin related to pneumatolitic processes, when skarns were formed. The more recent one was formed by hydrothermal processes and has the largest economic importance. Over 70 minerals have been recognized in the Trepca deposit. Further mineralogical investigations will allow for the identification of other rare minerals.

Badania ewaporatów prowadzone są bardzo intensywnie zarówno ze względu na to, że są to surowce niezmiernie cenne dla wielu dziedzin gospodarki, lecz także, a może głównie ze względu na to, że z ewaporatami często współwystępują złoża ropy i gazu. Zrozumienie wielu zjawisk występujących w czasie sedymentacji, diagenezy, a także metamorfizacji ewaporatów ma podstawowe znaczenie poznawcze i przyczynia się do poprawnych decyzji związanych z poszukiwaniem obu wspomnianych paliw. W publikacji zaprezentowano różne rodzaje zbiorników ewaporacyjnych i różne sposoby naturalnego zagęszczania słonej wody. Przedstawiono także różne rodzaje kryształów pochodzenia ewaporacyjnego wskazujące na różne sposoby krystalizacji ewaporatów. Zaprezentowano także przykłady krasu solnego i omówiono sposoby krystalizacji form pochodzenia krasowego krystalizujących z minerałów ewaporacyjnych.
Research on evaporates is conducted very intensively, which is both due to the fact that they are of utmost value to many branches of economy, and also (and this seems to be the main reason) that often deposits of oil and gas are found close to evaporites. Hence the comprehension of phenomena may contribute, in a fundamental way, to correct decisions related to the exploration of both fuels. The publication deals with various theories concerning functioning of evaporate basins and various way of salty water condensation. Moreover various types of evaporate crystals representing differentiated way of evaporate formation and crystallization are presented. Additionally examples of karstic forms crystallizing at salt main are described and the way of their crystallization is explained.

This article presents the results of mineralogical and petrographical research of so called graphite pottery. The La Tène culture pottery samples from the valley settlement in Thunau am Kamp were tested. Stereoscopic, polarized and Raman microscopy methods were used in the studies. In addition to examination of graphite from archaeological pottery, Carboniferous Age coal was tested as a potential additive in the La Tène culture pottery masses. Studies were also carried out on graphites from a Bohemian deposit in Český Krumlov, not far from the La Tène culture settlement area of Lower Austria. Another examination included contemporary pottery masses made from local raw materials with natural carbon additives, fired at 750° C in both oxidizing and reducing atmosphere. It was determined that the studied pottery contains coal (probably from Carboniferous Age), not graphite. Due to firing of pottery in reducing atmosphere, it did not burn and did not turn into graphite. "Counterfeit" ceramic pots have been found at the site of Thunau, with only a dark surface layer containing a carbon additive.

Opis:

Some Saudi gold ores, such as that at Al-Amar mine, suffer from low leaching efficiency using the toxic cyanidation process. Only about 60% of the gold and 26% of the silver in the feed ore can be extracted at 0.2% CN– after 24 h and the rest percentages of these metals remained in leaching residues (tailings). These tailings contained 1.1 ppm Au and 4.3 ppm Ag. Reprocessing of tailings serves both for economic and environmental reasons. A petrography analysis of the mineral constituents indicated that the rock samples consisted primarily of sphalerite, chalcopyrite, pyrite and galena in decreasing order of abundance. An electron probe microanalysis quantitatively showed that gold and silver were finely distributed in the grain boundaries and within sphalerite, chalcopyrite, pyrite, and quartz. The dissemination of gold and silver in these hard minerals may be the main reason for their low recovery by cyanidation. Open air roasting of the tailings can release amounts of the disseminated gold and silver which can be extracted during leaching with the harmless thiosulfate ion S2O32–. After studying the different parameters, we found that the maximum possible extraction of gold and silver from the tailings roasted for 2 h at 400°C reached about 50% at 0.2 M ammonium thiosulfate, 0.3 M ammonium hydroxide, solid–liquid ratio ½ for 24 h. These achievements represent a possible exploitation of the accumulated 1.65 million Mg tailing waste containing significant amounts of gold and silver valued at about $73 million.

Opis:

The paper presents the results of experimental studies on the synthesis and thermodynamic stability of selected Pb-apatites in terms of criteria determining termination of the experiments. Based on the case study, we indicate difficulties in analysing the obtained experimental data. Time-resolved sampling of precipitate formed during a dropwise synthesis of pyromorphite was performed and the results were compared to the literature data. It has been concluded that the Ostwald ripening time for synthesized solids depends primarily on the chemical composition of the intended Pb-apatite phase. We presented that heterogeneity of precipitate affects its dissolution in terms of repeatability of the results and equilibrating time. A unique 9-year-long experiment on vanadinite stability at a pH range from 2.0-6.0 revealed that among all tested dissolution conditions only the reactions at the pH = 3.5 can perform as the basis for some thermodynamic calculations. It has been concluded that the rate of phase transitions in the Pb-apatites group can be misleading in terms of determining the equilibrium of the system, and the experimental setup designed particularly to provide reliable controls in this aspect should be involved. Means in this respect have been proposed.

Opis:

Borates at the Igdekoy-Doganlar locality were deposited in a Miocene lacustrine environment during periods of Paleogene to Early Quaternary volcanic activity. The mineral paragenesis consists of probertite – NaCaB5O7(OH)4 3H2O, ulexite - NaCa[B5O6(OH)6] · 5H2O, hydroboracite - CaMg[B3O4(OH)3]2 3H2O, colemanite - Ca[B3O4(OH)3] · H2O, halite, anhydrite, glauberite, smectite and illite. The major element, Ca, is higher in the lgdekoy-Doganlar deposits compared to the averages for andesite and the Earth's crust. Within the trace elements, notable enrichment is identified in Li, Se, As, Sb, Sr and Cs. Lithium and Se occur in sufficient concentrations to be considered as economically valuable by-products. B and Sr anomalies can be used as an important marker in the exploration for boron deposits. The Y/Ho ratio of the lgdekoy-Doganlar borates is close to chondritic values. The negative Ce anomaly in borates from the lgdekoy-Doganlar deposit suggests that deposition occurred under oxidative conditions. The Eu and Ce anomalies reflect a hydrothermal contribution of REE. Geochemical and geological data suggest that the lgdekoy-Doganlar borate deposits were formed in high-pH playa lakes that were discharged from volcanic and terrestrial environments under evaporative conditions due to the effect of arid-semi arid climate.

The sequence of the presence of minerals at the profile suggests the deposit is the result of evaporation of salty lake during drying of climate at the Sahara Desert. Mineral composition of evaporates suggest that Na-Cl reach like evolved to Na-Ca-SO4 phase and next was fully evaporated and coated with detrital sediments.

Opis:

Perlite is an amorphous volcanic glass-type rock which is collected in open mines in various parts of the world. In this study, eight different perlite samples, supplied from the mines located in the Bergama, Izmir region, were used. The perlite samples were structurally, morphologically, and mineralogically characterized via a wide range of analytical techniques such as Thermogravimetric Analysis (TGA), Fourier Transform Infrared Spectroscopy (FTIR), Brunauer-Emmett-Teller (BET) Surface Area Analysis, Optical Microscopy, Scanning Electron Microscopy (SEM), X-ray Diffraction (XRD), X-ray Fluorescence (XRF), and a liquid pycnometer. Platelet shaped-like structures were observed in the SEM analysis of the expanded perlites in contrast to the images of spongy or cracked expanded perlites reported in literature. The O-H bending and Si-O-Si vibrations (both asymmetric and symmetric stretching) of perlite structures were confirmed by FTIR. Highly amorphous phases with a rather low percentage of crystalline phases were observed by XRD. In the BET surface area analysis, expanded perlite materials exhibited higher surface area compared to unexpanded ones. A detailed characterization of perlite structures is essential as there is a significant potential to use these minerals in various biocomposite applications and it is useful to explain structure-property relationships in this class of materials.

The Chelopech epithermal arsenic bearing high-sulphidation, copper-gold deposit located in Bulgaria is often considered as the richest European gold deposit. Selected physicochemical parameters have been measured at key flotation streams inside the processing plant. Sampling campaign has followed with samples being submitted to chemical and mineral liberation analyses. A quantitative analysis has enabled to link copper flotation response to the type of copper bearing minerals and physiochemical parameters such as redox potential (Eh), dissolved oxygen (DO), EDTA extractable Cu and Fe. Data from the mineral liberation analysis (MLA) have highlighted an important process- relevant information explaining the variable floatability in different particle size ranges. A low chalcopyrite recovery can be linked to the non-sufficient amount of dissolved oxygen inside the copper selective flotation. Given the finely-disseminated copper bearing minerals, copper losses due to particle locking could be suggested as well.

Opis:

This paper involves the results of oedometric tests carried out on four model samples with different content of expansive clay minerals, subjected to different stresses. The research aimed to determine the impact of consolidation pressure on the consolidation coefficient for cohesive soils with different mineral composition. Main factors influencing correlation between consolidation coefficient and consolidation pressure (Cv–p) trends turned out to be mechanisms controlling changes in soil volume (mechanical or physicochemical), which is different for expansive and non-expansive soils.

Opis:

El-Hudi gold deposit, located in the South Eastern Desert of Egypt, represent large vein- type gold occurrence. The representative sample revealed the abundance of quartz as main constituent with minor amounts of mineral impurities. Gold was detectable (12 g/t) as determined using atomic absorption. The petrographic study revealed that the gold grains ranged from 10-40 μm. The grain boundaries of quartz are highly stained with iron minerals as hematite and limonite. Sericite mineral is common in discrete gold-bearing veins. Eroded pyrite was detected with high alteration leaving only cubic-shaped cavities behind. Different techniques for gravity separation were used to separate gold from the quartz mineral. After crushing and grinding of the sample, shaking table was used to upgrade the coarser fractions while Falcon concentrator was employed to upgrade the fine fraction. The best concentrate was obtained through grinding the whole sample to less than 0.2 mm, followed by cleaning steps. The gold content is increased from 12 to 145 g/t with total recovery of 78%.

Investigation of Carcinoma basocellulare solidum exulcerans, Carcinoma basocellulare superficiale multicentricum, and Trichoepithelioma was performed using histology and biomineralogical methods. Obtained data confirmed elevated levels of some elements in altered skin tissues. Moreover, rare micrograins of phosphates were observed. Additionally, examination of biomineralization of human tissues suggests that higher local mineralization (of tissue fluids) may lead to mistakes in DNA code at the moment of cell division. It is possible that cancer tissues are secondarily mineralized by activity of cancer cells. Further research is needed to answer questions that arose.

Opis:

Park Burren-Marlbank jest jednym z bardziej znanych obiektów Neolitycznych w którym występują kamienne a megality oraz liczne dowody aktywności człowieka w tym ryty skalne. Przedmiotem opracowania jest sprawdzenie struktur i składu mineralnego skał znajdujących się poza rejonem parku, pod kątem genezy niektórych obiektów. Próbki do badań pobrano z miejsc występowania skał w naturalnych odsłonięciach by nie niszczyć chronionych obiektów Parku. Przez analogie interpretowano rzeźby i ryty skalne dzieląc je na wykonane przez człowieka i te które powstały w wyniku procesów geologicznych.
Due to the protection of monuments in the Neolithic archaeological site of Burren-Marlbank, Ireland, mineral and petrographic studies of local rocks in their natural outcrops have been undertaken. Those rocks were used during the Neolithic period for both construction of architectural sites as well as for various types of objects and rites. Stereoscopic, polarizing, scanning microscopy, as well as Raman spectroscopy were used in the studies. Obtained results and conclusions can be applied by analogy to the protected antique stone objects at the site. The results prove that due to lack of siliceous raw materials, local Neolithic tools were made of extruded rock of porcelanite characteristics. Recognition of inventory of stone tools will allow us to determine types of Neolithic man’s activities at the site. sandstones, which influences their different susceptibility to weathering processes. That caused the formation of natural erosive forms with macroscopic features on the rocks, suggesting their creation by human hand. Recognition of natural rocks allowed us to determine features that distinguish between rocks that have been affected and not affected by human activity, based on the degree of cracking of the grains in the surface rocks. The research shows that coal deposits may have existed in Carboniferous rocks at the Burren-Marlbank site area. Perhaps it was the local coal used in hearths in the Neolithic period (in the absence of another fuel due to poor plant representation) that was the decisive factor in the location of the settlement in this place. This hypothesis and the obtained results should be tested in further research.

Opis:

The maximum recovery of rare earth resource from the Bayan Obo ore deposit is a difficult task, especially without the sufficient data of mineralogy. In this paper the mineralogy of Bayan Obo ore deposit by comprehensively research with the application of mineral liberation analyzer (MLA) is reported. The MLA was applied to quantitatively analyze the complicated element/mineral compositions, the REE occurrence, the size distribution and the degree of liberation of the Bayan Obo ore. Mineralogical analysis of the rare earth ore has shown that REEs are present mainly as bastnaesite and monazite-(Ce) to a small extent as parisite-(Ce). 5.85% of the REEs, 34.99% of iron and 0.12% of niobium occur in the ore sample. There are 76.99% of iron occurred in hematite and the remaining iron is mainly distributed in magnetite and goethite. The degree of liberation of bastnaesite and monazite(Ce) was 79.65% and 75.67% respectively when the grinding fineness was 83.57% passing 75 μm sieves. Un-liberated or partly liberated rare earth minerals are associated closely mainly with other rare earth minerals and gangues. These theoretical data could be employed to further comprehensively utilize the rare earth ore.

Opis:

Geometallurgy is a growing area within a mineral processing industry. It brings together tasks of geologists and mineral processing engineers to do short and medium term production planning. How-ever, it is also striving to deal with long term tasks such as changes in either production flow sheet or considering different scenarios. This paper demonstrates capabilities of geometallurgy through two case studies from perspective of Minerals and Metallurgical Engineering division Lulea University of Technology. A classification system of geometallurgical usages and approaches was developed in order to describe a working framework. A practical meaning of classification system was proved in two case studies: Mikheevskoye (Russia) and Malmberget (Sweden) projects. These case studies, where geometallurgy was applied in a rather systematic way, have shown the amount of work required for moving the project within the geometallurgical framework, which corresponds to shift of the projects location within the geometallurgical classification system.

Opis:

In this study, comparative experiments were conducted on the recovery of quartz using flotation with different fluid inclusion abundances. A large number of fluid inclusions with various sizes have been found in natural quartz. Micrographs, inductively coupled plasma, electron probe microanalysis, homogenization temperature, Raman spectra, zeta potentials, X-ray photoelectron spectroscopy, scanning electron microscope, and energy dispersive spectrometer were used to characterize the fluid inclusions and quartz, as well as the adsorption tests and single mineral flotation experiments to investigate its floatability. The results demonstrated that it was more likely for quartz with higher fluid inclusion abundance to connect with Fe3+ sufficiently to achieve a high level of flotation recovery, due to the powerful collecting ability by sodium dodecyl sulphonate to Fe3+. Furthermore, the mechanism indicated that the adsorption between quartz and Fe3+ was a process of chemisorption.

Opis:

The Kremna Basin is located in southwest Serbia, in the Zlatibor area, which is part of the Internal Dinarides. This basin is noteworthy because of the type of bedrock drainage, which it represents. It was formed on ultrabasic rocks and volcanic materials that influenced the occurrence of organic matter (OM) in the basin fill. The objective of the study was to determine the organic geochemical characteristics of sediments from the central part of the Kremna Basin. The sediments studied belong to an intrabasinal facies, in which two sequences were distinguished. The lower sequence occurs at depths of 216–343 m, while the upper sequence is found from 13.5–216 m. At the start of basin development (265–343 m) sedimentation took place in shallow alkaline water, rich in Mg ions. Through time, a slight deepening of the basin occurred. This was followed by chemical deposition of carbonates (216–265 m). The most important change in the sedimentary environment occurred with the formation of sediments marking the transition between the sequences (at about 200 m). Sediments from the lower sequence are characterized by the dominance of dolomite and magnesite. There are indications of volcanic activity, i.e. tuff layers and the presence of searlesite. The upper sequence is characterized by the prevalence of calcite and dolomite. The amounts of MgO, Na2O and B are higher in the lower sequence, whereas the CaO content is higher in the upper sequence. The sediments contain different amounts of immature OM (late diagenesis). Biomarker analysis shows diverse precursors of the sedimentary OM: methanogenic archaea, photosynthetic green sulfur bacteria (Chlorobiaceae), bacterivorous ciliates, various bacteria, both photosynthetic and non-photosynthetic, the green unicellular microalga, Botryococcus braunii race A (exclusively in the upper sequence) and terrestrial plants. The lower sequence contains lower amount OM, composed primarily of kerogen II/III and III types, indicating a higher contribution of the allochtonous biomass of land plants from the lake catchment, particularly in the lower part. The sediments of the upper sequence are enriched in autochthonous aquatic OM, which comprises mostly kerogen I, I/II and II types. The transition from the lower sequence to the upper one is associated with a decrease in pristane to phytane ratio, gammacerane index and content of C28 steroids, absence or significantly lower amount of squalane, absence of C24 and C25 regular isoprenoids, 8-methyl-2-methyl-2-(4,8,12-trimethyltridecyl) chroman and C30 hop-17(21)-ene. Pyrolytic experiments showed that the sediments of the upper sequence, rich in aquatic OM, at a catagenetic stage could be a source of liquid hydrocarbons. The values of hopane, sterane and phenanthrene maturation parameters indicate that through pyrolysis at 400°C the samples investigated reached a value of vitrinite reflectance equivalent of approximately 0.70%. It was estimated that the sediments should be found at depths of 2300–2900 m in order to become active source rocks. The calculated minimum temperature, necessary for catagenetic hydrocarbon generation, is between 103 and 107°C.

Opis:

In order to rationalize the development and utilization of the wall rock discarded during rare earth mining, chemical analysis, inductively coupled plasma-atomic emission spectroscopy, X-ray diffraction analysis, artificial panning, optical microscope analysis, mineral liberation analysis and energy-dispersive spectroscopy were used to study the process mineralogy of the wall rock. The results show that the main useful elements in the rare earth wall rock were iron, light rare earth elements, fluorine and niobium. Iron was mainly occurrence as magnetic iron in magnetite, rare earth elements in bastnaesite and monazite, fluorine as a independent mineral in fluorite and niobium in columbite. The main useful minerals were finely disseminated, with magnetite (48.16%), bastnaesite (49.04%), monazite (42.18%), fluorite (39.30%) and columbite (63.26%) distributed in -0.030 mm particle size. The useful minerals were evaluated separately for beneficiation based on the process mineralogical characteristics of the rare earth wall rock, and the results showed that magnetite, rare earth and fluorite resources could be effectively recovered using magnetic separation, flotation, gravity concentration and leaching enrichment methods. The sequential recovery of iron, rare earth, fluorine and niobium elements produces iron concentrate (65.40% TFe at recovery of 38.03%), rare earth concentrate (50.66% REE at recovery of 62.73%), fluorite concentrate (95.23% CaF2 at recovery of 40.34%) and niobium iron ore concentrate (1.63% Nb2O5 at recovery of 5.56%). This study provides recommendations for the rational development and utilization of rare earth wall rock and provides reasonable levels of recovery predictions.

Opis:

The successful development of shale gas requires a fundamental understanding of shales and that can be challenging because these rocks vary significantly. For recoverable shale gas resources assessment a broad range of geological, geochemical, geophysical and geomechanical data is required. Information about the variable lithologies, mineralogies, and kerogen content is vital to locate favorable intervals for gas production. Knowledge of the in-situ stresses and porosity of these intervals is essential for developing hydraulic fracturing strategies to recover the gas in place. Geomechanical properties of shales are important in terms of determination of the likelihood of fractures initiating and propagating in shale materials. Geomechanical properties of rock include: Poisson's Ratio, Total Minimum Horizontal Stress, Bulk, Young and Shear Modulus. These properties play significant role in developing shale assets. Having access to geomechanical data can assist engineers and geoscientists during geomechanical modeling, hydraulic fracture treatment design and in some cases during reservoir modeling in shale gas fields. This paper is intended to give characterization of geomechanical properties of shale rock. It then refers to a case study of Baltic Basin of shale gas in Poland, for discussing it geological condition and rock properties.

Opis:

The Hateg basin, South Carpathians, Romania, contains a thick sequence of Maastrichtian continental deposits from which a rich dinosaur and mammal fauna is known. Field data as well as mineralogical and stable isotope analyses from three representative profiles were integrated in order to reconstruct environmental conditions during Maastrichtian time. Tustea quarry is characterized by the presence of well drained calcisols, with smectite (montmorillonite) as the main clay component. Along the profile, the δ18 O and δ13 C isotopic compositions of calcretes show a small variation, of up to 0.9‰. The profile along the Barbat Valley shows preponderantly calcisols, the main clay mineral being smectite, with subordinate illite and chlorite. The oxygen isotopic compositions of calcretes are ~0.5‰ lighter than those from Tustea. The soils are interpreted as having formed under more humid conditions and they are similar to those situated at the bottom of the sequence developed along Sibisel Valley. The abundant smectite from the Tustea and Barbat Valley depos its, as well the presence of good developed soils, reflects palaeoenvironmental conditions predominantly controlled by climate. Preliminary magnetostratigraphic data along the Sibisel Valley section indicate that sedimentation started at the end of chron C32n. All other palaeomagnetic sites distributed up stream, as far as the upper limit of this formation, have only reversed polarity and the corresponding time interval is probably chron C31r. Along this valley, the sequence shows a general coarsening upward trend. The palaeosol type changes from calcisol- to vertisol-dominated sequences. The soils are moderate to weakly developed. The mineralogical composition of the clay fraction also changes, from smectite- to illite and chlorite-dominated. These features points to wards unstable tectonic conditions and higher uplift rates of the surrounding area within chron C31r. To wards the top of the sequence, the oxygen and carbon isotopic composition of calcretes be come 1 and ~2‰ lighter, respectively. These changes indicate a transition from generally semi-arid to wards more humid and possible cooler conditions and correlate with the world wide trend for chron 31r.

Opis:

The role of ore properties (density, particle size, and mineralogy) in thickening process was studied in this research. The shaking table was used to prepare the sample for the tests. The tailings were continuously fed on the table by gravity to separate the tailings in three products as slime, middling and coarse particles. The solid density and particle size of the samples were different. To study the effect of mineralogical properties, the sedimentation behavior of the feed and middling samples were tested. The results showed that the free settling velocity of the feed (2–6 mm/s) was less than that of the middling sample (18–23 mm/s), and the compressibility of middling (density: 0.63–0.86 Mg/m3) was more than that of feed (density: 0.33–0.47 Mg/m3). This was due to the amount of clay reduction in the middling sample. The sedimentation behavior of the slime and the coarse samples were also compared in order to study the effect of particle size and density. The settling velocity of the slime and the coarse particles was obtained as 0.1-0.4 and 26 mm/s, respectively, and the maximum underflow density were obtained as 0.35 and 1.57 Mg/m3, respectively. Therefore, the particle size and density reduction reduced the thickener performance. In order to study the effect of particle size, the sedimentation behavior of the slime and coarse samples were compared, and it was obtained that the settling velocity and underflow density increased with the increasing in the particle size.

Opis:

In previous study, the promising results of separating enargite from non-arsenic copper sulfides were obtained using selective surface oxidation in pure mineral systems. However, this technology was not well understood in real ores or concentrates. In this study, the flotation separation of enargite from complex copper concentrates by selective surface oxidation was investigated. The effects of regrinding, pulp pH, NaClO concentration, conditioning time and flotation time on separation of enargite from NECu minerals were studied. The mineralogical characteristics of the flotation feed and products were showed as an instructive tool to understand the separation results. According to the results of EDTA extraction, the possible mechanism for separation of enargite from NECu minerals is that enargite is more resistant to oxidized compared to NECu minerals. The following order for the oxidation of NECu minerals and enargite is obtained: chalcopyrite (chalcocite, digenite)> enargite (covellite).

Opis:

Wykonano badania mineralogiczne i geochemiczne poziomu pochówku po około 1800 latach od pochowania zmarłego w grobie kultury wielbarskiej nr 134 w stanowisku archeologicznym Babi Dół. Stwierdzono, że makroskopowo brak jest jakichkolwiek śladów pochówku. Badania drobnych frakcji piasku z poziomu pochówku wykazały występowanie w nich drobnych fragmentów brązów. Badania przestrzeni międzyziarnowych i ziarn kwarcu wykazały występowanie na ich powierzchni niezidentyfikowanych substancji w postaci cienkich nalotów organicznych, organiczno-mineralnych oraz czysto mineralnych. Ich skład chemiczny wskazuje, że są one efektem procesów destrukcji pochówku i jego wyposażenia. Wykonane badania kilku grobów z tego stanowiska wskazują, że wody gruntowe wyprowadzały produkty dekompozycji pochówków i zabytków metalowych do przepływającej w pobliżu rzeki Raduni.
Mineralogical and geochemical tests of the burial level were made about 1,800 years after a burial of a deceased in the Wielbark culture grave No. 134, in the archaeological site Babi Dół. Macroscopically, no traces of the burial were found. Investigation of fine fractions of sand from the burial level showed presence of small pieces of bronze. Exploration of intergranular spaces and quartz grains led to the discovery of unidentified substances on their surface, in the form of thin organic, organic-mineral and pure mineral coating. Their chemical composition indicates that they are the result of processes of destruction of the burial and its furnishings. Studies of several graves from that site indicate that ground water has moved the burial decomposition products and metal artifacts out to the nearby Radunia river.

Opis:

The deposits under study (Brzostów, Krotoszyn, Ostrzeszów, Góra) and the Leszno borehole are located in Southern Wielkopolska, Polish Lowlands. Geochemical characteristics of the upper part of the Neogene Poznan Formation were presented on the basis of major elements analyses. The sediments were classified as clays, silts and sands. Quartz in coarse fraction and clay minerals (smectite, mixed layers smectite/illite, kaolinite, traces of chlorite and halloysite) in fine fraction are the main components. Their chemical composition depends mainly on mineralogical content. The sediments were strongly depleted in Ca and Na during weathering processes. Calculated chemical indices of alternation, CIA and CIW range from 59.9 to 91 and 68 to 93 respectively, indicating intense chemical weathering phenomena.

Opis:

Amenability of mafic ores to pre-concentration was investigated with respect to ore mineraliza-tion characteristics. For the pre-concentration tests seven ores from various nickel-copper operations at Sudbury, Ontario were subjected to dense medium separation. Size assays of metal values, i.e. distribution of nickel and copper with respect to size fractions, were also determined. The ores were assessed in three categories of valuable mineralization as massive pure sulphides, coarse massive sulphide grains and disseminated sulphides. For ores with massive pure sulphides and coarse massive sulphide grains even a size classification based pre-concentration route could be sought since a clear trend of metal enrichment was identified towards finer fractions. Orebodies of similar mineralogy had similar responses to pre-concentration tests. The best results were for those ore bodies with a distinct differentiation between mineralization and gangue, i.e. the ores with massive pure sulphides, where nickel recoveries of 97% and mass rejections of 38-53% were achieved. Similar results were obtained for ores with coarse massive sulphides. For disseminated sulphide mineralogy relatively lower mass rejection was attained with acceptable recoveries of metals. Rejection of magnesium bearing gangue, such as talc, was identified as another benefit of pre-concentration. The extent of magnesium rejection occurred as a function of ore mineralogy. Clear distinction between valuable mineralization and gangue provided preferential magnesium rejection at high levels with no or minor metal losses.

Opis:

The Middle Buntsandstein Subgroup of the Lower Triassic of north-eastern Poland has been investigated in the context of possible marine ingressions into the Central European Basin. To better constrain these, palynofacies analysis and mineralogical analysis of mudstones were undertaken on samples taken from the Lidzbark and Malbork formations penetrated by the Bartoszyce IG 1 borehole, serving as stratotype section of both lithostratigraphic units. Microfacies and geochemical analyses, including C and O isotope analysis, were conducted additionally on oolitic limestones of the basal Lidzbark Formation (the lowermost Middle Buntsandstein), and the boron content was measured on all mudstone samples. Seven palynofacies types are distinguished: types 1 to 3 within the Malbork Formation and types 4 to 7 within the Lidzbark Formation. Types 1 and 2 originated on a floodplain, type 3 probably in a deltaic or barrier setting, and types 4 and 5 in a brackish lagoon or a more open basin, possibly of marine origin. Palynofacies type 6 reflects long transport and reworking, whereas palynofacies type 7 is interpreted as formed due to pedogenic processes. Clay minerals and quartz, accompanied by feldspars, calcite and dolomite are the main components of the mudstones investigated. The clay mineral association consists of illite or a mixture of illite and smectite, and chlorite. The Lidzbark Formation and the lowermost part of the Malbork Formation show less variability in mineralogical composition than the upper part of the Malbork Formation. Smectite admixtures were detected only in the upper part of the Malbork Formation (the uppermost Middle Buntsandstein). The boron content, achieved after aqua regia digestion, ranges from 70 to 121 mg/kg (96 mg/kg at average), oscillating generally around 90 mg/kg. A higher boron content, bound in silicate structure, is associated with the upper part of the Malbork Formation. All major mineralogical and geochemical changes coincide more or less with the transition from the supposed marine to the terrestrial environmental realm, interpreted from lithological and sedimentological observations within the lowermost part of the Malbork Formation. However, diagenetic alteration of the clay minerals, and of the boron content, could not be ruled out. The oolitic limestones, mainly grainstones, contain admixtures of quartz grains and rare bioclasts, the ooids nuclei being peloids or unrecognizable. The carbonates are almost exclusively composed of low-Mg calcite. A high content of Mg and the presence of small amounts of dolomite suggest that the ooids were primarily composed of high-Mg calcite and are comparable with similar Early Triassic deposits in Tethyan settings. The δ13C values range from -2 to +1%o VPDB, fitting well with the known ranges of Lower Triassic marine carbonates. An observed δ13C depletion towards the top of the oolite-bearing part of the section may reflect a local shallowing trend that led to overall salinity decrease. A possible connection with the one of the global oceanic geochemical episodes has to be tested further. The results obtained suggest a marine origin of the lower Middle Buntsandstein deposits studied and document a terrestrial origin for the upper Malbork Formation.

Próbki pochodziły zarówno z cegieł jak i materiału znajdującego się miedzy cegłami, Badania wykazały, że temperatury wypału ceguieł i materiału znajdującego się miedzy nimi okazjonalnie w niektórych miejscach przekraczały 800o C. Ponadto małe, pojedyncze fragmenty żużelków i ziarna metalu (żelazo z tytanem) zostały odkryte w materiale znajdującym się między cegłami. Badania dowodzą, że temperatura panująca w całych obiektach była zdecydowanie zbyt wysoka do produkcji piwa.
Mineralogical, petrographical as well as geochemical investigation of so called “brewery “ discovered in Tel el Farkha archaeological site were performed. Samples of roller shape bricks as well as accompanying material for examination were collected. Examination showed temperature of firing of bricks of all discovered “brewerys” were at some places even above 800o C what is difficult obtain without additional air blowing. Observed microscopically thermal alternation of bricks of all places et examined objects was to high for production of bier. Examination confirmed at some places the presence of small fragments of Fe slag, and rare grains of metals (pure iron).

Slags containing both copper and iron were found during several seasons of field research in the old mines in the area of Lubietowa, near Banska Bystrzyca. Their presence proves that both copper and iron smelting functioned in the region in the past. Testing of the slags was carried out in order to determine their mineral composition, and indirectly also to learn about the conditions of melting for both metals. Further search for places of iron and copper smelting in the region is expected.

Opis:

The article presents the way in which the term “geology” in its today’s meaning was formed. The reasons for its consolidation among the naturalists in Poland and throughout Europe are pointed out. Thanks to the scientific influence of the father of European mineralogy A.G. Werner (1749-1817), the term geology was in some cases replaced by geognosy and oryctognosy. In turn, the father of Polish geology, Stanisław Staszic (1755-1826), favoured using the term ziemiorodztwo (“terrogenesis”). Probably, for the first time the term geology was used in Polish in 1804 by Józef Wybicki (1747-1822), the creator of the national anthem “Dąbrowski Mazurka”, and by Jan Śniadecki (1756-1830), an outstanding geographer, mathematician and astronomer.

Opis:

Salinty of soils is the factor leading to the limitation of agriculture. Due to the reduction of suitable fields farming is also reduced. As a consequence farmers have to leave farms. This problem is specially important in Egypt where cultivated land is limited to the Nile Valley. A mineralogical and geological investigation of this phenomenon is conducted at Heracompolis and surrounding areas showed the presence of the following minerals as white salty coatings covering the surface of local soils: The absence of natural floods of Nile stopped due to the construction of the Aswan Dam is the reason for the continuous elevation of the degree of the salinity of soils. Evapotarion of water used for agriculture cannot be prevented but the process of mineralization has to be stopped if Egypt wants to avoid reduced food production.
