The paper presents investigation on diagenesis of Muschelkalk carbonates in the 25-BN Biskupice borehole, NE part of the Silesian-Cracow region. A cycle of dissolution and neomorphic alterations has been identified in the dolomites, Fe-dolomites and calcites occurring at the medium and late stages of diagenesis based on the analytical results of petrographic, cathodoluminescence and SEM methods.

The study of new occurrences of Pb-Zn mineralization in the Lower Triassic rocks in the NE part of the Silesian-Cracow region was performer. Pb-Zn ore minerals occur in sandstones, gravels and oolitic dolomites and are represented by galena, sphalerite, pyrite, marcasite and an admixture ofchalcopyrite. Vein minerals: barite with celestite, calcite and partly anglesite were also found.

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.
