Abstract
Selected trace elements in the Upper Permian (Zechstein) salt and potash- bearing deposits in Poland – valuation of potential reserves.
A b s t r a c t. Content analysis of trace elements (Ag, As, Ba, Be, Br, Cd, Ce, Co, Cr, Cs, Cu, Fe, Ga, J, La, Li, Mn, Mo, Ni, Pb, Rb, Sb, Se, Sn, Sr, Ti, Tl, U, V and Zn) in the Upper Permian (Zechstein, PZ1 to PZ4 cyclothems) rock salt, potash-bearing and zuber deposits in Poland is based on geochemical data (archival and published) of 1418 rock samples. The mean detected content of dominant elements is low (<up to 8 mg/kg). Several ones (e. g. Fe, Li, Mn, Sr and Ti) are more abundant (from 20 mg/kg to 7011 mg/kg for iron) but attributed to the insoluble admixtures such as sulphates (anhydrite, gypsum) and clay matter, or they from the iron-oxide pigment. Bromine content varies highly form low values (from several up to 190 mg/kg) in rock salts and zubers to >300 mg/kg in potash salts. The low mean content of most trace elements indicate that the analysed Zechstein salt deposits in Poland are negative as a source for economically acceptable exploitation of such required trace elements as lithium, boron, gallium, strontium, selenium, rubidium, thallium or caesium. These elements could be profitably received from the other natural deposits of sulphates, clay complexes, metallic ores or natural salt brines and mineralized thermal waters.
