“…The main elements and bromine content were detected in the potash-bearing deposits of PZ2 and PZ3 cyclothems, drilled in the sixties and seventies of the past century in the Fore-Sudetic area (Figure 1), were defined to calculate a bromine/chlorine index. Its value for the Older Potash (K2) was 0.22-0.46 and for the Younger Potash (K3)-0.19-1.2 (see: [81]).…”

Mineral composition and content analysis of selected trace elements (Ag, As, Ba, Be, Br, Cd, Ce, Co, Cr, Cs, Cu, Ga, I, La, Li, Mn, Mo, Ni, Pb, Rb, Sb, Se, Sn, Sr, Ti, Tl, U, V, and Zn; 308 rock samples) were studied in the Upper Permian (Zechstein) potash-bearing deposits in Poland. They represented K–Mg chlorides of PZ2 and PZ3 cyclothems from four salt domes and stratiform K–Mg sulphates of PZ1 cyclothem. The dominant mineral components of K–Mg sulphates (polyhalite) are anhydrite and polyhalite. The most common minerals of the K–Mg salts of PZ2 cyclothem are halite, sylvite, kieserite, and anhydrite, and the most common of PZ3 cyclothem are halite, carnallite, kieserite, and anhydrite. Most analysed trace elements in the Zechstein potash-bearing deposits show a low content (up to 26 mg/kg) that eliminates them as potential profitable source rocks of such required elements as Ce, Cs, La, Li, or Rb. Common elements, such as Br, Fe, and Sr, are more easily exploited from natural brines, sulphate, and ore deposits.

A study of the bromine content and facies in the salt successions (representing PZ1, PZ2 and PZ3 cycles) from the Late Permian (Zechstein) salt basin in Poland evidences fluctuations in mother brine concentrations. The study indicates that the local (better recorded in facies of the shallow basin and its margins) and regional changes were the result of Late Permian climate variations and eustatic sea-level rises and drops.The observed trend for a lowering of brine concentration is attributed to more humid climate periods accompanied by frequent rainy seasons. Such a change from arid to more humid climatic conditions was observed in all three studied cycles, proving the variations of a dominant warm and dry climate, assumed for the inner part of the Pangea supercontinent in the Late Permian. The coastal zone of the Pangea supercontinent was more affected by the atmospheric perturbations, which were more frequent at the boundary between the continent and the ocean. The intracontinent areas were characterized with a more stable climate, thus interpreted by the authors, that the climate changes in the successions coming from the inner part of such intracontinental basin, far from the continent coasts (as the Polish part of the European Permian Basin) as the evidence for climate instability in the whole Zechstein period. The authors recorded the climate fluctuations in an area, which should be characterized with the most constant climate, particularly during the evaporite deposition. The prolonged more rainy periods that succeeded the warm and arid periods were recorded in the central part of the continent.Eustatic sea-level fluctuations, responsible for large changes in brine concentrations, became independent from the climatic variations. Sea-level rises initiated huge marine water input and caused extreme refreshing of the bottom salt brine in deep-water basin parts. Two such events were registered in salts of the PZ1 cycle, and a further three in the evaporite succession of the PZ3 cycle. A single rapid drop in sea-level, resulting from a postulated tectonic close of the narrow North Atlantic seaway that conducted ocean water to the evaporite basin, was detected in the lower part of the PZ2 salt succession. This caused the evaporite basin cutoff, its successive desiccation and, consequently, the production of potash-bearing salts.

Obrazowanie wybranych własności utworów solnych za pomocą różnych metod badawczych Artykuł przedstawia wyniki przeprowadzonych analiz materiału rdzeniowego z wybranych utworów solnych, reprezentujących cechsztyńską i mioceńską formację solonośną. W celu określenia charakterystycznych parametrów i własności badanych skał solnych wykorzystano następujące metody: rentgenowską tomografię komputerową (CT), analizę w skaningowym mikroskopie elektronowym (SEM), analityczne oznaczenia składu chemicznego, fluorescencję rentgenowską (XRF) oraz dyfrakcję rentgenowską (XRD). Zastosowane metody badawcze pozwoliły określić zróżnicowanie najbardziej charakterystycznych cech analizowanych utworów.Słowa kluczowe: sól kamienna, halit, komputerowa tomografia rentgenowska, skaningowy mikroskop elektronowy. Defining selected salt rocks properties using various research methodsThe article presents the results of well core analysis from salt rocks, representing the Zechstein and the Miocene salt formations. The following methods were applied in order to determine the characteristic parameters and properties of the analyzed salt rock: X-ray computer tomography (CT), scanning electron microscopy (SEM), methods of the chemistry identification, X-ray fluorescence (XRF) and X-ray diffraction (XRD). The applied research methods helped to identify the diversity of the most characteristic features of the tested rocks.
