Opis:
At a nature-preserve protected site in the Julian Alps (NW Slovenia), in the Pod Peski valley, red fillings of megalodontid bivalves occur within the Upper Triassic Dachstein limestone. Based on optical and cathodoluminescent microscopy and X-ray fluorescence (XRF) analysis, four generations of shell fillings were recognized, some of which contain both cement and sediment subgenerations. Logging and sampling of the limestone sequence a few meters below and above the “main” layer containing the megalodontids mentioned above revealed that the limestone is characterized by solution voids similar to the megalodontids. Namely, these voids are also filled with reddish multigeneration sediment with alternating calcite cement. Adjacent neptunian dykes were studied to clarify their influence on the last generation fillings. Two of them, located directly on the “main” layer with red-filled megalodontids, contain planktonic foraminifera, indicating Middle Jurassic or younger age. The next two neptunian dykes are located directly above the “main” layer, and one contains clasts with calpionellids characteristic of the Late Jurassic/Early Cretaceous. The last dyke explored is located a few tens of meters from the “main” layer and is several hundred meters long. In a few sample from this dyke Early Cretaceous planktonic foraminifera were identified. Microscopic analysis revealed that the reddish sedimentary fillings are part of a complex palaeokarst system that produced the first three generations of fillings, and in the last (fourth) generation we noted similarities between the megalodontid fillings and neptunian dykes on the “main” bedding plane. In addition, a Santonian–Maastrichtian sedimentary fill with globotruncanid foraminifers were discovered in the upper part of the succession in one of the solution voids.

Opis:
The Mendeleev Rise (or Mendeleev Ridge) is a part of Central Arctic Uplifts domain that extends from the Eastern Siberian Shelfto the central areas of the ocean, where it is adjacent to the Alpha Ridge bisecting the Amerasian Basin. The crust of Mendeleev Rise belongs to the continental type (Poselov et al. 2007). New geological, geophysical and tectonic data were obtained within Alpha-Mendeleev Rise after few expeditions to Arctic Ocean in year 2000, 2005 and 2012. Thousands of rock fragments were dredged: 50–65% – carbonate rocks (mainly dolomite and limestone); 20–25% – sandstones, siltstones, mudstones; 5–20% – igneous rocks (mainly granites, gabbro-dolerite and few types of basalt); ~ 10% – metamorphic rocks (mainly greenschist facies). Light dolomites with little flora and fauna represent about two-thirds of the total amount of carbonate rocks, the rest are limestones, often containing well-preserved faunal remains. Paleontological study of limestones show abundance of D-P 1 fauna remnants that give us an evidence of structural connection of Mendeleev Rise and Wrangel Island (Morozov et al. 2013). Carbonate crusts were dredged from steep slopes (25–29°) with neotectonic faults on two sites at water depth more than 2 km during expedition “Arktika-2012”. Primary study showed that crusts compose of strong matrix with rounded and angular debris of local (edaphogenic) material: dolomites, dolerites, granites, metasomatic and terrigenous rocks of different size (0.5 mm to 5 cm) (Morozov et al. 2013, Kremenetskii et al. 2015). Three samples of matrix and two of soft clay-carbonate crust’s cover were selected for detailed analysis. Petrographic features were studied using optical microscope, microprobe and X-ray analysis. Chemical elements analysis was performed with XRF and ICP-MS. All analyses were carried out in A.P. Karpinsky Russian Geological Research Institute (VSEGEI) in Saint-Petersburg. AAC’s Matrix studied with microprobe in details and consists offine-grained calcite with angular quartz grains from 1 μm to 300 μm. X-ray analysis shows calcite predominance in the matrix (>70%), rest content is presented with clasts of quartz, illite and albite – about 10%, dolomite, chlorite, montmorillonite, chamosite – 1–2%. Clasts of local debris are presented by two association: 1) large, mainly angular clasts with size from 0.5 mm to 5 cm; 2) small, mainly rounded clasts with size from 200 μm to 0.5 mm. Surface of matrix and debris is covered with soft rose clay-carbonate mass. Mineral content of clay-carbonate mass is: quartz and illite – 25–30%, calcite and albite 15–20%, chlorite, orthoclase, halite, dolomite, montmorillonite – 1–5%. Chemical composition (in percents) of matrix is close to clay-carbonate terrigenous rocks: SiO 2 – 18, Al 2 O 3 – 3.62, TiO 2 – 0.2, Fe 2 O 3 t – 1.4, MnO – 0.05 MgO – 2.35, CaO – 39.2, Na 2 O – 0.18, K 2 O – 0.47, P 2 O 5 – 0.12, L.O.I. – 34.3. Rose mass differs from matrix with silica – 46, CaO – 19, higher alkalis (Na and K) – 1.15 and 1.3. Difference in content of silica (18% vs 46%), CaO (39.2% vs 19%) says that AAC matrix and rose mass have various sources. In contrast to Paleozoic remnants in carbonates, the AAC contain planktonic and benthic foraminifera of Pleistocene age. In Arctic seas, these species are distributed in modern conditions mainly in places where the Gulf Stream arrives (Herman 1974). These data indicates local origin of ACC, main evidences includes distribution, good preservation of samples, local debris in matrix, paleontological age. However, carbonates are very limited in the Arctic Ocean (Emelyanov 2005, Chierici & Fransson 2009). In view of these parameters, AAC can’t form by itself so it may be due only to external factors. Bottom water doesn’t provide such factors. Neither necessary conditions nor material occur in these waters. So in our opinion AAC were formed with help of neotectonic fault which are supposed to be a possible path for hot fluids, which created the conditions for crusts forming and Paleozoic carbonate rocks was a source of CaCO 3.

Opis:
The Zalas quarry is located in the southern, marginal part of the Silesian-Cracovian Monocline. Permian rhyodacite laccolith has been exploited here for over 70 years. The intrusion was formed about 260–280 Ma during the Early Permian transtensional, sinistral tectonic regime predominating in central Europe at that time (Nawrocki et al. 2005). Permian volcanic rocks are overlain by a Middle–Upper Jurassic sedimentary sequence, built from sands and sandstones, substituted with the passing of time by limestones and sandy limestones rich in fossils (Matyszkiewicz et al. 2006). Quarrying operations carried out approximately 10 years ago uncovered a fault zone cutting the Middle Jurassic sandy limestones. Exposed breccias was locally encrusted by a hydrothermal mineralization forming thin veinlets cutting the limestone, or surrounding the breccia clasts. Primary mineralization contained small relics of pyrite, chalcopyrite, chalcocite, galena, native bismuth and barite and was significantly replaced by supergene minerals e.g. Fe and Mn oxides, malachite, cuprite, Cu sulphates, iodargyrite, Bi oxychlorides and Na, K chlorides (Gołębiowska et al. 2006, 2010, 2015). The mineralization is most likely connected with rejuvenation of Early-Paleozoic fault zones during the Sava phase of the Alpine orogeny, and subsequent intensive weathering under semi-arid and arid climate in a period between the Oligocene and Middle Miocene (Gołębiowska et al. 2010). In the sandy limestone encrusted by the oxidized mineralization, very interesting Mn-oxides, enriched in numerous heavy metals were encountered. They filled small fractures and voids within the fault breccia. Among them, Tl-rich varieties have been recently reported. Extremely high thallium content, reaching 20.82 wt% Tl 2 O, makes the oxides unique on a world scale (Gołębiowska et al. 2015). In this paper we focused on the variable admixtures in Mn oxides from oxidation zone in Zalas; for this purpose, SEM-EDS and WDS analyses were carried out. Mn oxides in Zalas are accompanied by malachite, Fe oxides (goethite and hematite) and relics of primary mineralization (Matyszkiewicz et al. 2015). Mn and Fe oxides commonly form the yellowish to red-brownish or black tiny grains or cryptocrystalline aggregates with sizes up to a few millimetres across. Manganese oxides contain variable admixtures of Cu, Ca, Pb, Ba, Fe, Ni, Co and Tl. On the basis of chemical analyses, three major Mn oxide types have been distinguished: those enriched in (i) Ni and Co, (ii) Pb and (iii) Ba and Ca. Co-Ni-bearing Mn oxides, probably asbolane-type, contain 17.01–21.58 wt% CoO and 3.05–8.33 wt% NiO. These phases contain also admixtures of Cu (up to 10 wt% CuO) and Al (up to 7 wt% of Al 2 O 3 ), as well as traces of Fe, Ba, Zn, Mg and Tl (up to 0.5 wt%). Interestingly, in Mn oxides of this type, the admixtures of lead are absent. Pb-bearing Mn oxide, probably coronadite, contain up to 21.48 wt% PbO. In its composition various other elements were also noticed: up to 2 wt% CoO, 0.4 wt% NiO and very high concentrations of CuO up to 8 wt%, as well as up to 1 wt% BaO, FeO, CaO Tl 2 O, Al 2 O 3 and traces of Zn and Mg. Chemical mapping indicates that the Ba- or Ca-bearing Mn oxides occur only in marginal parts of zoned MnO 2 aggregates with almost pure MnO 2 in their cores. They contain 78–84 wt% MnO 2, 3–10 wt% BaO and 2.5–4.5 wt% CaO. High contents of Co, Ni, Pb, Cu and Tl in Mn oxides from Zalas indicate a direct link with the primary ore assemblage. High concentration of cobalt and nickel might suggest some connection with Co and Ni mineralization known from nearby Karniowice Travertine (Czerny 1992). Mineral association, as well as crystal morphologies and sizes could indicate hydrothermal origin of at least part of the Mn oxides. However, identification of the particular minerals as well as concluding on the details of their origin is quite difficult on this stage of research.

Opis:
The Great Pyramid in Giza is the most researched and most recognisable object from the ancient world (Arnold 1991, Raynaud et al. 2008). Observations of its walls showed difference in colour of some limestone blocks used for building its core. Different colour of blocks results from the amount of fossil shells contained in the limestone. The large number of fossils not only gives the limestone its colour but is also responsible for its hardness. (Badawy 2005). Blocks made of this type of limestone form a triangle in all four walls of the pyramid. Precision of masonry and their fitting is better than that of blocks made of other kind of limestone. The triangles in the pyramid walls were made from a special type of limestone. The Giza plateau consists mainly of middle Eocene nummulite limestone which belongs to the Mokkatam formation. The limestone is partly overlain by late Eocene limestone of the Maadzi formation (Lehner 2004). The main purpose of this paper is to determine the mineralogical and petrographic composition of the blocks, which were used to build the Great Pyramid. Due to the insufficient amount of the veneer blocks, the study focuses on the stones which were used to build the core of the pyramid (Folk & Campbell 1992). According to the author, the better preserved blocks forming the triangles occupy the central parts of the pyramid walls. The best preserved blocks are observed in the first layer. They lay in the distance of 40 m from the corners of the pyramid and they were put in the central part of the pyramid’s foundation. In each subsequent layer their number is decreasing from the both sides. And thus, occurrence of this type of limestone ends up with the single block in the 19th layer, in the central part of each wall. These blocks are lighter and precisely fitted. They are arranged in a characteristic way and create a triangle-shaped feature. The same elements are visible in the next three walls of the Great Pyramid at Giza. The discovery of triangles in four walls of the Great Pyramid broadens our knowledge about its construction. The triangles have been unnoticed through the ages. After presenting the paper by the author, each person will be able to see the triangles without a problem, even on old photographs (Zalewski 2004, 2006). Concluding, the four triangles located at the base of the Great Pyramid at Giza are visible in the four walls of the pyramid. The best visible of them is the triangle located in the western wall, topped with a single stone. It is in the 19th layer of the stones, 16 m 65 cm high. According to the author’s calculations, the angle of all the above-mentioned triangles in its top amounts 155°. The length of its base is about 150 meters.

Khao Khwang Formation is widely distributed in central Thailand. It is represented by Late Pennsylvanian to Middle Permian thick-bedded limestone with chert nodules. Rock samples belonging to this formation have been collected. They are light to dark grey, thick-bedded to massive limestone with black nodular cherts. The abundant and extraordinarily gigantic bivalve Alatoconchidae together with fusulinoidean fauna (Verbeekina verbeeki, Colania douvillei and Pseudodoliolina pseudolepida), fragments of coral, ammonoid, brachiopod, sponge, gastropod, etc. were observed. Based on the characteristic fusulinoidean fauna, it indicates Capitanian in age. Microscopically, limestone samples were classified as bioclastic rudstone and packstone. The detailed lithologic and carbonate microfacies observations, Alatoconchidae beds, deposited parallel to the bedding plane and related with oncoids and microbial, are autochthonous in shallow marine. Condensed accumulation of other fossil fragments found in the study areas might be transported by gravity flow.

Opis:
A development project of the Zalew Balaton area is being presently carried out. One of the project assumptions is to create a geological path across the object. However, detailed data about the geological structure of this place is not available. For this reason, the author has researched and updated the information about the rocks occurring in the walls of the old quarry. Primarily, terrain (textural and structural analysis, layers strike and dip measurements, geological boundaries delimitation) and laboratory analysis (X-Ray Powder Diffraction, microscopic rock samples analysis) were conducted. Collected data was afterwards compared with available literature. Within the steep slopes of excavation, strong-karsted, faulted Upper Jurassic (Oxfordian) carbonate sediments were revealed. These are massive, platy and crumpled limestone. These rocks could be deposited in changing conditions of sedimentation, when calm carbonate sedimentation was disturbed by underwater gravity flows, as demonstrated by their detrital character. One of the karst funnel on the northern slope was filled with Oligocene sand. As a result, groundwater fluctuations created a sarsen structure, popularly called the “Wielbłąd”. In relation to the planned geological path across the Zalew Balaton area, previous knowledge should be supplemented with new data, respectively processed and included on information panes, located within object. Plans of the path should pay attention to potential geotouristic safety, as well as to the geological values of the protected object, during its future modernization.

Opis:
Black limestone, also known as black "marble", was widely used in the Polish small-scale architecture and art of the 17th and 18th centuries. Besides the Devonian limestone from Dębnik near Krakow, also popular were the Netherlandish (Wallonian), Devonian to Carboniferous limestones from the Meuse River and Schelde River valleys. This paper deals with the possibility of identifying the rocks imported to Poland. Macroscopic similarities between the Netherlandish rocks and some Dębnik limestones have been highlighted for the oldest Carmelite quarry in Dębnik, exploiting the best stones. The analyses include: optical microscopy, scanning electron microscopy with EDS, X-ray diffraction, X-ray fluorescence and isotope ratio mass spectrometry (13 C and 18 O stable isotopes). Carboniferous limestones from Netherlands can be identified within and distinguished from the Dębnik limestone in the macroscopic observations. Differences, depending on the varieties, are associated primarily with the presence of white calcite fragments of fossils, calcite veins intersecting the rock in all directions or hardness of the limestones. Deeply black Devonian limestones from Wallonia and Dębnik without macrofossils and calcite veins differ in microscopic observations considering their texture, type of microfossils and inventory of non-carbonate components. The characteristic graying and whitening of the black limestones has also been discussed as a possible feature of rock provenance.

Opis:
The early mediaeval period witnessed a considerable breakdown in masonry techniques and in architecture in the Polish territory: the application of stone and developing of skills of shaping rocks into regular cuboid stone bricks. Only local stones quarried within a distance of ca. 15 km from Krakow were used in early mediaeval edifices in the city. They were: two varieties of limestones (Upper Jurassic) and three varieties of sandstones of the Carpathian flysch (Cretaceous to Palaeogene). Sedimentary environments (facies) and post-sedimentary processes determined compactness, block divisibility and workability of stones, which, further on, determined their application. Thin bedded sandstone and platy limestone yielded easily workable and relatively small (few to a dozen of centimetres in length) and quite regular bricks used in the earliest buildings. Rocky limestone was a source of irregularly shaped clumps used initially as a filler of walls erected in the opus emplectum technique. Later, it was used also for cutting larger (few tens of centimetres), more regular blocks. Bedded limestone was a good material for obtaining larger (a dozen or two dozens of centimetres) regular bricks used widely throughout the whole early mediaeval period. Blocks (2 or more metres in length) of soft dimension Carpathian sandstone were used for shaping and carving large elements: tombstones, columns, volutes, epitaphs, etc. Techniques of quarrying and stone working developed considerable with time. Initially, slope scree and stone from demolished older ramparts were used. Later, quarries reached deeper beds which yielded larger bricks and blocks. Stone sources "migrated" with time too. The earliest places of excavation were located within the city, e.g. on the Wawel, Skałka and Krzemionki hills. When those deposits were exhausted, mining moved to more distant spots.

Eksploatacja wapieni karbońskich w Czatkowicach trwa od ponad 60 lat. Stanowi ona przykład selektywnego rozwiązania i optymalnego wykorzystania surowcowego niemal każdej występującej w złożu odmiany kopaliny. Sytuacja ta i gromadzone w ciągu kilku dziesiątków lat doświadczenie pozwoliły na kompleksowe użytkowanie wszystkich występujących w złożu odmian kopalin oraz realizowanie optymalnej gospodarki surowcowej stanowiącej wypadkową pomiędzy specyfiką surowcową kopalin z jednej strony, a podążeniem za wymogami rynku zbytu z drugiej. W efekcie tego Kopalnia pozostaje przedsiębiorstwem atrakcyjnym surowcowo. To z kolei posiada pozytywne przełożenie na jej sytuację finansową.
The Carboniferous limestones have been quarried in Czatkowice for more than 60 years. Their winning represents an example of a selective and optimum utilization of almost every rock variety occurring within the deposit. Such a policy and the experience gathered for several tens of years have allowed: introducing complex utilization of all limestone varieties present; - implementing optimum management of the deposit, which results from technological properties of the rocks quarried on one hand and the market requirements on the other. Due to that, the Czatkowice quarry is a mining venture providing sought for, attractive rock products. Their marketing secures the solid financial position of the company.

Opis:
At the time of discovering and exposing the scientific and educational potential of areas where mineral resources were exploited in the past, they have become a significant element in tourism elements. In the presented paper, the potential of the GEOsfera Ecological and Geological Education Centre in Jaworzno as a geoproduct was analysed. In the first part of the study, based on the published works and consultations with experts, the “geoproduct” was defined. Then the area, where the GEOsphere is located, was characterized. Its geology, the natural world, the way of land development and the promotion of geo-attractions located in this area are described. In the next stage, an analysis of the opinions of users regarding their perception of the GEOsphere was carried out. For this purpose, evaluations posted on social media and the collected survey results were used. As shown by the results, the majority of users of the GEOsfera are residents of Jaworzno – 63% of the respondents. The importance of the GEOsphere as an educational centre was indicated by 22% of visitors. About 5% of the respondents mentioned learning and obtaining information from the descriptions placed next to the exhibits in the centre. 93% of respondents recognised the graduation tower as the greatest attraction of the GEOsphere. Over 92% of people noticed the recreational role of the GEOsphere. 81% of users declared that they were satisfied with their visit to the GEOsphere. More than half of the respondents (56%) visited the GEOsfera with their family. A significant part of respondents (42%), pointed to the role of environmental protection, which is extremely important from the point of view of geoproducts’ design. The respondents also indicated that the GEOsphere has numerous geological, natural and educational functions and protects and promotes the geological heritage of the region.
W dobie odkrywania i eksponowania potencjału naukowego i edukacyjnego terenów, na których w przeszłości prowadzono eksploatację surowców, stają się one znaczącymi obiektami turystycznymi. W prezentowanej pracy dokonano analizy potencjału Centrum Edukacji Ekologiczno-Geologicznej GEOsfera w Jaworznie, zlokalizowanego na terenie wyrobiska surowców skalnych, jako geoproduktu. W pierwszej części opracowania, opierając się na dostępnych pracach publikowanych i konsultacjach z ekspertami, zdefiniowano „geoprodukt” oraz określono kryteria, jakie powinien spełniać. Następnie opisano teren, na którym zlokalizowana jest GEOsfera, uwzględniając geologię, elementy przyrody ożywionej oraz sposób zagospodarowania terenu i promowania geoatrakcji, które się tam znajdują. Na kolejnym etapie przeprowadzono analizę opinii użytkowników w zakresie postrzegania przez nich GEOsfery. Do tego celu wykorzystano oceny zamieszczone w mediach społecznościowych i zgromadzone wyniki badań ankietowych. Wykazały one, że większość spośród badanych użytkowników GEOsfery to mieszkańcy Jaworzna, którzy stanowili 63% ankietowanych. Znaczenie GEOsfery jako istotnego ośrodka edukacyjnego wskazało 22% odwiedzających. Około 5% pytanych doceniło uczenie się i pozyskiwanie informacji z opisów umieszczonych na tablicach obok eksponatów na terenie ośrodka. Jako największą atrakcję terenu GEOsfery 93% ankietowanych wskazało tężnię solankową. Ponad 92% respondentów dostrzegło rekreacyjną rolę GEOsfery i dogodne warunki do aktywnego spędzania czasu. 81% badanych zadeklarowało zadowolenie z wizyty. Ponad połowa respondentów (56%) odwiedziła GEOsferę z rodziną. Znaczna część ankietowanych (42%) zwróciła uwagę na znaczenie ochrony środowiska w funkcjonowaniu GEOsfery, co jest niezwykle ważną informacją przydatną podczas projektowania geoproduktu. Użytkownicy, którzy wzięli udział w badaniu, wskazali również, że GEOsfera ma liczne walory geologiczne, przyrodnicze i edukacyjne oraz chroni i promuje dziedzictwo geologiczne regionu.

Opis:
Region lubelski stanowi niezwykły przykład koegzystencji górnictwa, budownictwa i przetwórstwa surowców skalnych, których korzenie od paleolitu poprzez średniowiecze sięgają dnia dzisiejszego. Krzemionkowe surowce skalne w dolinie Wisły były aż do epoki wczesnego żelaza źródłem surowca do wyrobu broni i narzędzi, a korzystające z ich wytrzymałości ludy - prekursorami dzisiejszej geomechaniki. Dostępność węglanowych surowców skalnych górnej kredy oraz neogenu znalazła od średniowiecza swój wyraz w budownictwie obronnym, sakralnym i mieszkalnym Lubelszczyzny. Unikalne techniki górnicze wydobywania ich jako budulca kamiennego są przykładami twórczego połączenia wiedzy inżynierskiej, geologicznej i znajomości ich właściwości geomechanicznych. Na bogatym tle regionalnego górnictwa skalnego na szczególną uwagę zasługują opoki, których nietypowe właściwości geomechaniczne stanowiły podstawę ich ugruntowanej w średniowieczu przydatności budowlanej. W pracy przedstawiono charakterystykę cech wytrzymałościowo-odkształceniowych opok wraz z oceną podatności na deteriorację w drugiej skali czasowej na tle innych surowców skalnych Lubelszczyzny.
The Lublin Region represents unusual example of co-existence of mining, building industry and rock workings,. The roots of today's industries in the Lublin Region reach as far back as Medieval times and even farther back - the Paleolithe. Cherts from chalky limestones in the river Vistula Valley, until the beginning of Iron Age, were basic supply for the various tools and weaponry. Prehistoric artisans, knowing the mechanical properties of chert bearing rocks and knowing how to mechanically processing hard cherts, become precursors of today's geomechanics. Availability of common carbonate rocks of the Upper Cretaceous and Neogene made significant impact on building industry. The defense heavy fortresses, sacral monumental buildings, and magnificent residential and common buildings are typically made of white, chalky and siliceous limestone blocks all over the Lublin Area. In the paper are outlined geological aspects and geomechanical assessment of the special, regional rock building material resources in the Lublin Region - the siliceous limestone, their geomechanical properties, which became the base of traditional building industry. Under special consideration is the vulnerability of siliceous rocks to physical deterioration with the passage of time. The description of typical forms of destruction of stony building elements is completing the paper.
