Opis:
In the shadow of discoveries of large deposits of mineral resources in Poland after World War II, intensive exploration works were carried out, but the results of this research did not bring such spectacular effects. Exploration of Zn-Pb deposits conducted in the vicinity of historic deposits of Tarnowskie Góry and Bytom led to documentation of the Zawiercie, Goluchowice and Marciszów deposits. With some successes, exploration works of metal ore deposits in Paleozoic igneous and metamorphic rocks of the NE margin of the Upper Silesian Coal Basin were carried out. In this area, the Myszków Mo-W-Cu mineral deposit was confirmed, representing the porphyry copper genetic type. Moreover, in the area of Mrzyglód, the promising mineralization zone was found, requiring further geological research. The exploration of uranium and rare earth element ores did not lead to documentation of the deposits, nevertheless they made it possible to recognize all geological structures in Poland in terms of the possibility of occurrence of ore deposit occurrence of these metals. The prospecting works for these goals was carried out with a relatively small scale and were limited of the Sudetes, where exploitation took place on a fairly large scale in the past (Zloty Stok, Radzimowice, Klecza-Radomice, Wądroże Wielkie). The gold concentration occurring in the Zechstein Kupferschiefer formation and the porphyry copper mineralisation in NE margin of the Upper Silesian Coal Basin were also studied. The PGI participated in the exploration of mineral resources in marine areas, where besides the hydrocarbon exploration in the Polish economic zone, research on the Baltic polymetallic nodules was carried out, and within the INTEROCEANMETAL consortium the raw material potential of the Clarion-Clipperton Zone in the Pacific was studied.

Opis:
Defining a list of strategic deposits is an indispensable activity for preparing the mineral resources policy, a governmental programming and planning document serving to ensure long-term mineral security of the country. Some mineral deposits play a fundamental role in the functioning of the economy and therefore require special protection. Such deposits are referred to under various terms (strategic, key, deficit and critical mineral deposits). Until now, none of these terms has a normative character in Poland. As of 2019, the Polish Geological Institute-National Research Institute is prepares a list of strategic deposits on behalf of the Chief Geologist of the Country. To accomplish this task, a special methodology was developed (using and modifying previously published studies and proposals and the EU approach to critical minerals). Special attention was paid to the issue of legal protection of deposits in the system of planning protection. Based on multi-criteria analysis, deposits of local and regional, national and supranational importance and a list of strategic deposits have been defined. Special plan protection (strategic deposits and those recognized as equivalent for spatial planning) should be extended to 266 deposits out of more than 14 000 documented deposits listed in MIDAS database.

Opis:
For 155 years, the world's most famous diamond deposits have been known from South Africa. The first discoveries that had a casual character took place in the second half of the 19th century in the Kimberley region where diamonds are associated either with kimberlite pipes or occur as secondary deposits of the river alluvia. Minerals that formed in the upper mantle under high p-T conditions were transported to the surface by magmas and deposited around craters due to lava explosions. Surfice waters leached and transported diamonds either to the crater or to the neighbourhood. These processes have led to diamond production both from the deep and open-pit mines which is presented in the paper.

uranium deposits
Opis:
The plans for development of nuclear energy to cover Poland's needs for power raise the question of perspective domestic uranium resources. Prospecting for uranium deposits has been carried out with varying intensity since the end of the 1940s until the 1990s. In the early 1960s these works resulted in discovery of several uranium deposits and occurrences in the Sudetes. Outside of that region, uranium was also found and extracted from the Staszic piryte deposit in Rudki, the Holy Cross Mountains. Total production of uranium in these times in Poland is estimated at about 650 t. A new phase of prospecting was initiated by the Polish Geological Institute in 1956, resulting in discoveries of uranium mineralization in the Ordovician Dictyonema Shales in the Podlasie Depression and the Lower and Middle Triassic sediments in the Peribaltic Syneclise. Moreover, the so-called parallel studies, based on all the available geological and geophysical borehole data from the whole area of Poland, made it possible to analyze distribution of uranium in practically all geological units and formations in the country, especially in the Oligocene Menillite Shales of the Carpathians, the Carboniferous of the Upper Silesian Coal Basin, Zechstein copper-bearing shale and phosphates. The performed analyses, including large-scale geological works aimed at identifying uranium concentrations in the Dictyonema Shale of the Podlasie Depression, Triassic rocks of the Peribaltic Syneclise and Permo-Carboniferous rocks of the Intra-Sudetic Depression, gave us sufficient knowledge for evaluation of possible occurrences of uranium deposits in Poland. Based on our reanalysis of all available data, it may be stated that the Sudetic deposits are of historical importance only. The uranium concentrations known from Upper Carboniferous and Lower Permian rocks (Grzmiąca,Wambierzyce and Okrzeszyn deposits and mineralization shows found in adjacent areas) should be treated as areas with anomalous uranium contents but, unfortunately, without any greater economic significance due to low uranium content, low resources and often observed strong association of uranium with organic matter. The Rajsk deposit and uranium concentrations in the Dictyonema Shale formations (Podlasie Depression) are characterized by low grade uranium mineralization and occurrence at depths of over 400mand, therefore, can not be considered as a potential source of uranium. The Triassic rocks of Peribaltic Syneclise represent a possible uranium deposit of the sandstone type. However, because of large depth of occurrence (over 800 m), usually very high variability in uranium content and location mainly in areas under legal protectiont, these resources should be hypothetical, that is requiring further studies. It may be stated that the degree of recognition of radioactivity of individual geological formations and structures minimizes chances for discovery of any deposits of industrial importance.

Opis:
Textural and structural diversity of slope covers and alluvial deposits in the upper parts of mid-mountain valleys in the Eastern Sudetes allows for assessing human impact on their formation. Sandy-silty colluvial deposits in the lower parts of slopes or within local flats and slope depressions originate due to enhanced surface wash from arable grounds, in contrast to underlying coarser material with solifluctional features. Similarly, fine-grained overbank alluvial deposits can be also connected with human activity, as the slope material, washed down from arable fields, was transported to the channels and deposited within the floodplains during high-water stages. Their linkages with human activity have been confirmed by radiocarbon dating of charcoal found at the bottom of these sediments. The dates show a strong correlation with the dates of foundation of villages in the study area. The development of agriculture and deforestation of slopes resulted in increasing surface wash and transportation of slope material to footslopes and river channels. The extent of deposits, which can be correlated with human activity, is much more widespread than it was suggested before and they are found as high as 800 m a.s.l. Their thickness, however, is visibly smaller in comparison to colluvial or alluvial sediments deposited in the Sudetes foreland and it is strongly influenced by the local morphology. According to the 14C dating, these sediments are also much younger than those in the foreland, which corresponds to a substantial delay in human settlement expansion into the mountain areas.

The Polish Geological Institute - National Research Institute, acting as the Polish Geological Survey (PSG), is responsible for, among others, carrying out works of fundamental importance for the national economy, in particular for the renewal of the country's raw material base, determining the resources of mineral deposits, as well as for environmental protection. As part of this work and within the framework of the activities in the field of implementation of the State Raw Materials Policy, PGI-PIB undertook the valorization of documented mineral deposits of strategic, key and critical importance for the state economy. This valorization is also to include the determination of the spatial relationships of objects that hinder the operation or future commencement of the exploitation of deposits, in accordance with the requirements for the determination of functional areas set out in the National Spatial Development Concept 2030 (NSDC 2030 - repealed in 2020). In order to preserve the utility values of mineral deposits of strategic importance for the state economy, including the preservation of the energy security of the country in the perspective of 2030 and later years, the NSDC 2030 indicated the need to protect them against permanent buildings and line investments, among others by introducing restrictions on how these areas are managed.

Detailed macroscopic profiling of salt cores from selected wells drilled in the Góra salt diapir (central Poland; Fig. 1, 2) and analyses of bromine content made it possible to define and characterize lithostratigraphic units of the Zechstein (Upper Permian) succession (Fig. 3, 4). Interpretation of relations between the units identified in the studied well sections allowed the first schematic reconstruction of internal structure of top part of the salt trunk (Fig. 5). The principal idea of this reconstruction is probable origin of the Góra diapir as a salt trunk with a recumbent fold at the top (Fig. 6A). Subsequent uplift of the diapir and erosion resulted in removal of significant part of younger salt deposits so only those squeezed into the salt trunk interior escaped the erosion (Fig. 6B). Models of internal structure of salt diapirs are of remarkable practical value as they facilitate proper location of the mining works (e.g. leaching wells, galleries, chambers and caverns) and prediction of possible gas and water hazards.

Opis:
The PGI research of lignite was primarily focused in the area of eastern Poland. An extensive research of the lignite deposit geology mmediately after the end of World War II led to numerous discoveries of large lignite deposits, including some of the biggest in Europe (Legnica, Bełchatów, Poznań Tectonic Trough). The data collected during exploration and prospection of lignite deposits made possible to elaborate stratigraphy (litho- and palynostratigraphy) of Paleogene/Neogene lignite-bearing association on the Polish Lowlands and prepare its detail correlation with the stratigraphic schemes of East Germany. Sedimentological studies of lignite-bearing association led to the definition of basic types of lignite-bearing facies, related to sedimentary conditions in different zones of alluvial sedimentary basins. They also allowed the establishment of relationships between lignite-bearing sedimentation and tectonic evolution of the lignite basins in tectonic depressions and cups of salt domes. Recently, the impact of climate change on the development of brown coal sediments has been subject to study and the critical thermal conditions for the most intense anthracogenesis in the Polish Lowlands, which took place in Miocene, were defined.

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.

Studies on river terrace deposits using ground penetrating radar (GPR) were conducted on several river terraces in the Kamienica river valley, Polish Outer Carpathians. All GPR profiles were collected using RAMAC/GPR system with 50 and 200 MHz antennae. The study has been based on 10 GPR profiles from 40 m to 200 m in length from which two as the most characteristic are presented in the paper. Terrace sediments consist mainly of gravels with subordinate sand. A peat layer has been found in one profile. These deposits lie on strath terraces built up with flysch sandstones and shales. Most of the profiles show reflections suggesting that the deposits are composed of multichannel river deposits. Some features of the profiles also indicate the presence of strath terraces and a peat layer. Even though lithology and texture of the investigated sediments are not very diverse, GPR measurements are quite useful in a few aspects of terraces’ structure interpretation.

Opis:
The rock salts occur in Poland (Central Europe) in two salt bearing formations of the Upper Permian (Zechstein) and the Neogene (Middle Miocene) and the potash salts - in the Upper Permian only. The total resources of rock salts are estimated at over 84 x 109 Mg. The share of Permian salts is here predominating as resources related to 4 thick rock salt complexes with extent comprising almost two thirds of the area of Poland are estimated at over 80 x 109 Mg in 15 documented salt deposits both of stratiform and diapir types. These deposits are currently exploited in 2 underground salt mines and 2 solution mines and annual output totalled about 3.1 x 106 Mg in 2007(mainly from the diapirs). The most perspective future use of these rock salt deposits is construction of safe underground cavern storages for oil and gas(now 2 such ones already exist) and depositories. The Neogene deposits (stratiform and stratiform-folded), exploited in the past millennium, occur in a limited area in southern Poland and are now only of historical-touristic value. The potash salts, quite frequent in the Permian evaporite complexes, are documented in one salt diapir in central Poland where they are mainly represented by carnallite and kieserite with resources > 72 x 106 Mg and are occasinally exploitated on limited scale. They are also documented in sulphate horizons accompanying the rock salt seam in northern Poland (4 deposits of polyhalite with resources of ca. 0.67 x 109Mg). However, low market prices of potash products offered by the neighbouring countries e.g. Russia, Belarus, Ukraine, make exploitation of these domestic potash salt resources uneconomic.

Commercial deposits in impact structures are world-class range resources. They contain the most important resources of copper, nickel, uranium, gold, platinum group elements and hydrocarbons. Terrestrial craters are also sources of mineral waters and building materials, and they can be reservoirs of hydropower. There are three types of deposits in meteorite craters: progenetic – originate before impact, syngenetic – originate during impact, and epigenetic – result from postimpact processes. The estimated number of Earth’s craters suggests that impact structures can be potentially good sources of economic deposits and tourism resources.

Opis:
The paper presents the characteristics of types, occurrence and distribution of the ocean polymetallic deposits: polymetallic nodules, cobalt-rich ferromanganese crusts, seafloor massive sulphides and metalliferous clays. Possibility of extraction of critical raw materials (for the EU) and strategic raw materials (according the OECD report) from the ocean polymetallic deposits is indicated. Polymetallic nodules are the most recognized type of ocean polymetallic deposits, abundant mostly in abyssal basins at the depths of3500-6000 m b.s.l. The most important practical metals from the polymetallic nodules are: Fe, Mn (280 000-320 000 ppm), Ni (11 000-14 000 ppm), Co (2100 ppm), Cu (9500-13 000 ppm), Mo and rare earth elements (REE). Cobalt-rich ferromanganese crusts, which are laminatedferromanganese clusters occurring at a depth interval between 400-4000 m b.s.l., can have a prospective significance for the extraction of critical raw materials. They are found on the seamounts where seafloor currents have swept the rocky bottom clear of sediment. They contain large amounts of metals: Mn, Co, Ti, Pt, Te, Mo and Zr. The key factor determining the profitability of the crust mining will be cobalt extraction. However, profitability may increase if nickel, tellurium or REE would be recovered at the same time. The analyses show that the seafloor massive sulphides would be of great importance, as they are the potential source of gold, platinum, silver, copper, zinc and lead. Extraction ofthese deposits is associated with the smallest area ofexploitation and depth ofoccurrence (between 1500-3700 m b.s.l.) which can significantly facilitate commencing of mining operations. Their commercial extraction could begin in the next few years, provided a high concentration of gold and metals in the location near the coast, and a depth below 2000 m b.s.l. Metalliferous clays, which are the deposits enriched in manganese oxides or hydroxides and sulphides or iron, could become an important prospective source of rare earth elements. This is confirmed by a study in two regions: eastern South and central North Pacific. Prospective possibilities of mining the ocean polymetallic deposits increased due to a high concentration ofMn, Ni, Cu, Co, Pt and REE (La, Ce, Nd, Yb, Eu). REE recovery particularly increases the economic value of these deposits. Mining of the ocean polymetallic deposits would meet many technological difficulties and should be preceded by detailed environmental studies.

Opis:
Gas in shales occurs as a constituent of rock and its resources can be estimated in a similar way as the metal content in ore deposit. The cutoff gas content in rock is the basic parameter defining deposit boundaries. It is proposed that the cutoffs in gas-bearing rocks are 2 m3 gas/t and 15-m deposit thickness. In case of lack of sufficient data, the deposit boundaries for resources estimation may be delineated in a defined distance from prospecting boreholes, supported by geophysical data, if possible. Discovered gas resources may be evaluated by volumetric methods. For reserve estimation, dynamic methods should be applied based on shale fracturing results. Following the stages of prospecting and exploration, decreasing uncertainty of the deposit resources/reserves evaluation may be expressed by D, C, B and A categories, or with the use of PRMS classification system.

Opis:
The aim of the article is to analyze and indicate the basic principles of protecting mineral deposits at the stage of their exploitation. Despite the successively decreasing resources of mineral deposits and the increasing importance of environmental protection, not all aspects of the protection of these deposits have been transparently regulated by law, an example of which may be terms that appear therein which do not have legal definitions, such as rational mining and management of minerals or comprehensive mining and development of a mineral. The article introduces the essence of the mineral deposit, the regulations on the protection of mineral deposits contained in the Environmental Protection Law and the Geological and Mining Law, as well as the related obligations of entrepreneurs engaged in the extraction of minerals from deposits.
