Between 1976–1990, the Polish Geological Institute performed geological works in the Polish Maritime Areas. During these works, 260 occurrences of concretions were recorded from 7,500 sampled sites. In 1980, the threshold that separates the Bornholm Basin from the Słupsk Furrow was mapped. Numerous Fe-Mn nodules on the seabed were found in that area. The results of detailed analyses of nodule samples collected from four sites are presented in this paper. Analyzed nodules represent discoidal D, irregular I, and transitional D-I types. The nodules are characterized by varied chemical composition of main oxides (Fe, Mn). The maximum Fe2O3 content is 26.63% and MnO 23.18%. Total average amount of REE + Y in the samples is approximately 165.11 ppm, ΣLREE 145.72 ppm and ΣHREE 19.39 ppm. The LREE content is enriched in comparison to HREE. The majority of nodules consist of Fe-Mn oxy-hydroxide minerals with very low crystallinity (practically amorphous phases). The main confirmed Mn-phases are birnessite and todorokite. Other main components of the nodules are: detrital quartz, albite, microcline, glauconite and muscovite, clinochlore, and clay minerals: illite and chlorite. The rate of growth of Fe-Mn nodules has been estimated using a cobalt chronometer. The nodule growth rate ranges from 0.006 to 0.134 mm/yr –1. Based on the Fe, Mn and (Cu + Co + Ni) contents, the origin of studied nodules is determined as hydrogenetic, while using REE (Cesn/Cesn · vs. Nd) – as diagenetic.

Fine-grained siliciclastic rocks from the Triassic-Jurassic transition (Rhaetian–Hettangian) in the former Mid-Polish Trough were the subject of the geochemical study at the Polish Geological Institute – National Research Institute in Warsaw. Ninety-four samples of claystones and mudstones from six archived drill cores were analysed by ICP-MS and XRF for rare earth elements (REE) and other trace elements. The results indicate that the sources of most of the claystones and mudstones were sedimentary rocks of the upper continental crust of old cratonic areas, where the protolith had a moderately felsic character. Weathering and recycling processes modified the original chemical composition to some extent. However, during Rhaetian and early Hettangian, some geochemical data in the south-eastern segment of the MPT suggest significant input from a mafic volcanic protolith. Moreover, a clear enrichment in rare-earth elements was observed in few samples, caused by admixtures of accessory minerals (being a main carrier of REE). Nevertheless, based on currently obtained data, the Rhaetian–Hettangian concentrations of REE (and other trace elements) in the MPT are low and they are of scientific indicative significance, not of raw material importance.

The paper presents an interesting decorative flooring solution from 1973 on the ground and first floors of the main building of the Pedagogical University of Cracow, named after the Commission of National Education. This flooring is composed of irregular, variably coloured natural stone slabs: the so-called Holy Cross Mountains „marbles”. They represent several rock types from limestone quarries near Chęciny, including mainly Bolechowice, but also Szewce, Łabędziów and Jaźwica. These rocks are traditionally called marbles. However, in fact, petrographically, they are not metamorphic rocks, but strongly lithified and massive, partially crystallized limestones with numerous fossils. They are of Paleozoic age: Middle and Upper Devonian. The type of flooring composed of irregular panels of different sizes and colours is currently rarely used in interior design despite giving an aesthetically pleasing mosaic effect with an interesting pattern. The flooring made of assorted Holy Cross Mountains “marbles” can have a great educational value and great geotouristic significance. Selected and described rocks of different lithological types can be used to create a geotouristic educational path that will be helpful in teaching of subjects related to Earth sciences (e.g. geology, paleontology, rock materials).

The article discusses the lithological and facies development of the copper ore deposit in the Fore-Sudetic Monocline in the so-called depression at the top of the Weissliegend. The lithological variability and quality parameters of the deposit in the exploitation field located between the Central and Northern elevations of Rudna, where the deposit profile is described as “typical”, i.e. the Cu-Ag mineralization occurs in all three basic lithological types of copper ore, is analyzed. The lithological variability of ores in depression zones is the reason why the degree of mineralization and the parameters of the economic deposit are highly variable. The authors focused on the mutual relationships between the neighbouring lithological units and the development of the balance deposit. To illustrate the variability of deposit parameters closely related to the lithological and facies development of the host rocks, three-dimensional lithological and geochemical models and isoline maps of the thickness of individual specific copper ore types were made using geostatistical methods and based on field observations and sampling of the deposit.

Jurassic limestones of the Kleszczów Graben are among the most important accompanying raw materials in the Bełchatów lignite deposit. In recent years, there has been a need to recognize their suitability as SO2 sorbents for use in the energy industry. The limestones are characterized by high lithological variability. They show both high hardness and compactness, and are weakly concise or even silty. At the top parts, they are subjected to karst processes. The lower parts are affected by secondary mineralization processes, among which the silicification process is most advanced. The effects of other transformation processes, such as compaction, cementation, dissolution and recrystallization of calcite are also visible. These processes contributed to a significant diversification of the mineral and chemical composition of limestone, and differentiation of physico-chemical and physical-mechanical parameters responsible for assessing the suitability for their commercial use as a raw material for the production of SO2 sorbents. Other problems associated with documenting the limestones in the Bełchatów deposit are related to their lesser importance compared to the main mineral. Its degree of exploration is low, characterized by a lower density of exploratory boreholes and significantly longer average lengths of samples collected from drill cores. At the present stage of the accompanying mineral exploration, only a preliminary estimation of limestone resources as potential SO2 sorbents is possible. The precise estimation will be possible after constructing a 3D model of criterion parameters and developing an extraction scenario.

Social acceptance for mining activity is one of the important elements determining its success. In addition to formal and legal conditions related to the nature of protection and spatial planning, it is one of the major barriers that limit or even hold back this activity. Over the last several years, a constant increase in such unacceptance can be observed in both Poland and most of the European countries, although the degree of occurrence of this phenomenon is diverse. It is confirmed by surveys carried out by the author as part of the already completed EU Minerals4EU project. The paper discusses the results of these studies and attempts to explain the reasons for the negative attitude of societies to mining activity. The activities undertaken to change the attitude are also presented, in particular the Social Impact Assessment (SIA). The objectives of the assessment are similar to the purposes of generally applicable Environmental Impact Assessments: identification of all possible limitations of planned exploitation, and their evaluation and minimization, necessary to obtain a favourable environmental decision, and, in the case of the SIA, to obtain social acceptance for the planned mining investment. In some EU countries, e.g. Denmark and Greenland, the development of a separate SIA report is a compulsory element of concession proceedings. The paper discusses the adopted formal scope of this document and the advantages of such a solution, enabling the anticipated operation of the future investor to achieve the planned goal.

Mineral Raw Materials are of strategic importance for Europe’s economic growth and societal development. The European Commission addressed this challenge through the Raw Materials Initiative (RMI), stakeholders’ platform, the European Innovation Platform on Raw Materials (EIP-RM), and Horizon 2020 funding. The aim is to ensure security and sustainability of mineral raw materials supply from EU domestic and other primary and secondary sources and management of competing uses of the European surface and subsurface. The sustainable supply of raw materials from European sources requires an improved knowledge base of raw materials within the EU, namely the European Union Raw Materials Knowledge Base (EURMKB), where EuroGeoSurveys, the Geological Surveys of Europe, is one of the key data providers. Current European Commission policies have the same objectives that will be fully implemented in near future. The Mobility Package and its implementation activities (such as European Battery Alliance) and tools (including Horizon Europe) will strengthen the raw materials position in an overall EU policy setting.

The paper presents a possibility of estimating the content of ore minerals based on chemical analyses of copper-bearing sedimentary rock samples from the North-Sudetic Synclinorium and from the Fore-Sudetic Monocline using a calculation procedure similar to the CIPW norm. The mineralogical data was obtained by means of an optical microscope and an electron microprobe (EPMA). The quantitative composition of gangue minerals was determined using the XRD method, and of the ores by the computer microscopic image analysis (CAMI). The actual set of gangue and ore minerals, their chemical composition, and proportions of copper ores were determined in the samples. Elements that are the main components of identified minerals were selected. The calculation procedure has been developed in accordance with the mineralogical and chemical data. The set of ore minerals determined based on the calculation of the weight ratios is consistent with the microscopic observations of copper-bearing rocks. The obtained ore contents are similar or slightly higher in poorly mineralized samples and slightly lower in highly mineralized samples in comparison to the results of the CAMI method. These differences may be due to different methods of averaging samples (powdered, averaged rock samples, and a thin section). The calculated ore proportions are consistent with those obtained by the CAMI method. The study calculations of the quantitative ore mineral composition using the calculation procedure analogical to the CIPW norm can be used to a preliminary approximation of the quantity of ores in geological prospection and exploration studies, but they require testing of more variants of the element partition between the set of minerals.

The mineralogical data was obtained by means of an optical microscope and an electron microprobe (EPMA). The quantitative composition of gangue minerals was determined using the XRD method, and of the ores by the computer microscopic image analysis (CAMI). The actual set of gangue and ore minerals, their chemical composition, and proportions of copper ores were determined in the samples. Elements that are the main components of identified minerals were selected. The calculation procedure has been developed in accordance with the mineralogical and chemical data. The set of ore minerals determined based on the calculation of the weight ratios is consistent with the microscopic observations of copper-bearing rocks. The obtained ore contents are similar or slightly higher in poorly mineralized samples and slightly lower in highly mineralized samples in comparison to the results of the CAMI method. These differences may be due to different methods of averaging samples (powdered, averaged rock samples, and a thin section). The calculated ore proportions are consistent with those obtained by the CAMI method. The study calculations of the quantitative ore mineral composition using the calculation procedure analogical to the CIPW norm can be used to a preliminary approximation of the quantity of ores in geological prospection and exploration studies, but they require testing of more variants of the element partition between the set of minerals.\u0000\u0000","PeriodicalId":321173,"journal":{"name":"Biuletyn Państwowego Instytutu Geologicznego","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115799687","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
