Opis:: For a century - since the initiative of a group of parliament members to constitute the Polish Geological Institute (PGI) was supported by the Polish Parliament on May 30, 1919 - the PGI has success fully fulfilled all basic responsibilities and commitments that are conventionally assigned to national geological surveys. Like in the past, in modern geological surveys the research is of great importance and it is clear that they cannot exist without science, the same applies to the PGI. The scientific knowledge achieved during the implementation of geological survey tasks is important for the society and the country's development.

Opis:: The characteristic of ore mineralization in the immediate vicinity of fault zones in the Lower Zechstein deposits is shown. All presented outcomes are on the basis of rock material taken from mining profiles in the Radwanice-Gaworzyce deposit area. During conducted studies ore minerals and oxide minerals were identified under optical microscope in reflected light and photographic documentation of the examined samples was undertaken. In addition, microprobe examination was carried out for selected samples from the studied profiles along with calculations of the chemical composition of individual ore minerals. In all analyzed profiles, Rote Fäule oxidized zone (enriched with hematite) was found, which occurs at various levels of the Kupferschiefer series and the reduced zone (enriched with ore minerals) over the oxidized series. The redox front cuts across the boundaries oflithostratigraphic units, moving from the Weis- liegend to the higher parts of the Zechstein Limestone. The primary ore mineralization in the examined profiles is the chalcocite-digenite association with subordinate bornite and covelitte recorded in the reduced series. Furthermore, the secondary sulphide mineralization in the direct vicinity of tectonic deformation and faults superimposed on primary ore mineralization and hematite enrichments is observed and it is represented by chalcopyrite, bornite, tennantite, tetrahedrite and pyrite, both within reduced and oxidized zones.

Opis:: The characteristics of spatial distribution of silver minerals and Agin ore minerals within the Lower Zechstein formations at the contact zone between reduced rocks and the Rote Fäule oxidized rocks are shown. All presented outcomes are on based on rock material taken from mining profiles and some archival boreholes in the Radwanice-Gaworzyce deposit area. These studies were used microscopic observations in reflected light and by microprobe analyses using the CAMECASX-100. In all analyzed profiles, oxidized rocks (enriched in hematite) were found, which occur at various levels of the Kupferschiefer series beneath the reduced zone enriched in ore minerals. Silver in the reduced zone occurs in the form of its own minerals, such as: native silver, stromeyerite, mckinstryite, jalpaite, naumannite, silver amalgams. Futhermore, silver is present as Cu and Fe isomorphic substitutions in the crystal lattice of copper sulfides of the Cu-S and Cu-Fe-S groups and in As and Sb sulfosalt. In the oxidized zone, silver occurs as electrum, silver amalgams and substitutions in remnant copper sulfides. A decrease in the concentration of silverin ore minerals and in the content of silver minerals towards the top of the mineralized interval is characteristic. The concentration of silver (both in the form of its own minerals and as isomorphic substitutions in ores) is impoverished in the zone where the oxidation front crosses the Kupferschiefer shale than in the case when the stabilization of the redox front is at the border boundary of the Weissliegend sandstone with and the Kupferschiefer shale. The spatial distribution of silverin the Lower Zechstein formations at the contact zone between the reduced and oxidized rocks is the result of the evolution of ore mineralization, caused by the flows of mineralizing solutions, as evidenced by the depletion of the oxidized zone in silver, and its enrichment in the adjacent reduced rocks.
