W artykule scharakteryzowano osiarkowanie warstw baranowskich (miocen, baden) zapadliska przedkarpackiego w rejonie złoża siarki Osiek-Baranów Sandomierski. Osiarkowanie to ma znacznie większy zasięg niż w poziomie ewaporatowym i cechuje się dużą lokalną zmiennością rozkładu (zasięgu poziomego i pionowego, stopnia osiarkowania i grubości warstw siarkonośnych), taką samą w strefie samego złoża, jak i poza nim. Osiarkowane są głównie piaskowce. Siarka rodzima występuje zwykle w postaci grudek i gruzłów siarkowych. Inne formy siarki, takie jak: impregnacje siarką i masywne osiarkowanie oraz żyłki siarki są rzadsze. Osiarkowanie jest największe w najwyższej części warstw baranowskich (do ok. 3,5 m miąższości) w której zawartość siarki, przy jej dużej zmienności, jest przeważnie niska (2%) i średnio wynosi 4%.

The study presents the main features of native sulphur mineralization of the Baranów Beds (Badenian, Miocene) occurring beneath the Osiek-Baranów Sandomierski native sulphur deposit (northern, marginal part of the Carpathian Foredeep). The extent of mineralization exceeds significantly that one developed in the overlying evaporitic series. The native sulphur mineralization of the Baranów beds is characterized by a high local variability of distribution, i.e. both the horizontal and vertical extents, degree of sulphur mineralization, and thickness of sulphur-bearing beds. These parameters are the same as beneath the sulphur ore body as outside the deposit. Sandstones are the main sulphur-bearing rocks, and native sulphur occurs mainly as granules and nodules, other forms like dispersed or massive sulphur mineralization as well as sulphur veins are less common. Relatively enriched in native sulphur is the uppermost part of the Baranów Beds (of 3.5 m thick) which, however, is generally characterized by a high variability of sulphur concentration and low sulphur content (predominantly 2% S and 4%S at average).

The paper presents interpretation of total organic carbon (TOC) content and carbon isotopic composition of organic matter within the Miocene/Pliocene Poznań Formation deposits recorded in BK 110 borehole in the Konin area (Central Poland). The TOC content as well as a :13C(TOC) PDB values vary widely throughout the deposits, from 0.1% to 6.1% (0.6% at average) and from –14.2‰ to –26.2‰ (–23.2‰ at average), respectively. The distribution of these parameters within the series allow to distinguish the lower part, which is thinner and enriched in organic matter accumulation, and the upper part, which is thicker and clastic. The a:13CTOC values indicate that C3 plant material prevailed in the lower part, while the upper part contains of C3+C4 plant material or C3 + marine organic matter. The subdivision of the Formation into lower and upper parts reflects a shift from peat-bog vegetation in nearshore lake into brackish lagoon environment with a periodical supply of terrigenous land material. The shift in the origin of the organic matter and sedimentological features of the Poznań Formation sediments imply a tectonic event or/and climatic shift, possibly connected with evolution of plants population and thus relative decrease in C3 and increase in C4 organic material at the Miocene– Pliocene boundary.

Results of distribution analysis of major, minor, and trace elements content as well as isotopic features and organic matter (TOC) concentration within clastic (mudstones and claystones with sandy interbeds) of the Middle Miocene (Badenian–Sarmatian) Machów Formation in the northern part of the Carpathian Foredeep (southern Poland) are presented in this paper. A chemostratigraphic study shows that theMachów Fm, underlain by evaporites (Krzyżanowice Fm) may be subdivided from the base to the top into three complexes: A, B, and C. Lithologically, the boundaries between the complexes are continuous but the contrasting geochemical difference occurs between A and B+C complexes. According to geochemical features, supported by palaeontological data, this chemostratigraphic boundary is assumed as the Badenian–Sarmatian one. Such approach reveals that the chemostratigraphic boundary occurs much higher (up to several metres) than the palaeontological one. The discordance in the boundary location is ascribed to palaeoecological factors.

As part of the tasks performed by the Polish Geological Survey (Polish Geological Institute - National Research Institute), 260 prospective maps (MOP) at a scale of 1 : 200,000 have been developed in the period of 2013-2015. These maps were designed for metal ores (Cu-Ag, Zn-Pb, Mo-W, Ni, Sn, Au, Pt, Pd and Zn oxide ore - galmans) and chemical raw materials (rock and potash salts, gypsum, anhydrite and native sulphur), in relation to the assessment of raw materials resources and environmental restrictions and land use planning. The total surface of prospective teritories projected onto the surface area is ~15.25 thousand km2 for metal ores and ca. 52.5 thousand km2 for chemical raw materials. The estimated resources of predicted ore deposits (prognostic and prospective) are approx. 42.2 million Mg of Cu and 75 thousands Mg of Ag (12 prospective areas), ca. 20 million Mg of Zn-Pb ores (in 4 prospective areas), 32 million Mg of Ni ores of weathering type (10 prospective areas), from 9.4 to 21.5 Mg of Au encountered by orogenic vein and metasomatic deposits (7 prospective areas), and ca. 22 million Mg of Sn ores. The estimated prognostic and prospective resources of chemical raw materials (at a depth of not more than 2000 m) are: ca. 4.059 trillion Mg of rock salt (68 prospective areas) and ca. 3638.1 million Mg of potash (12 prospective areas), as well as ca. 575.6 billion Mg of gypsum and anhydrite, and 202 million Mg of native sulphur (prognostic resources). In the assessment of environmental conflicts and land use planning, 125 information data sheets developed environmental conditions for prospective areas (with the exception of rock salts, which are discussed in the regional aspect). Development of the designated prospective areas may be important in the future to ensure the availability of raw material safety, not only for Poland, but also for the European Union, thus contributing positively to economic growth and prosperity of local communities.
