Abstract
THE RESULTS OF RECENT STUDIES ON POTASSIUM SALTS FROM THE FORE-SUDETIC REGION
Summary
Two horizons of potassium salts, correlable with German Stassfurt K2 and Ronnenberg K3Ro horizons, occur in Zechstein section of the Fore-Sudetic region. The Stassfurt K2 horizon comprises alternations of red-coloured rock salt, rock salt with sylvine, and hard anhydrite-polyhalite salt layers. Potassium content is usually lower than 10 per cent of K2O, increasing only in places of increased thickness of this horizon. The Ronnenberg K3Ro horizon ,comprises light-gray hard kizerite salts with K2O content up to 16 per cent. In places, about a dozen meters below this horizon, ,a series of rock salt with thin polyhalite intercalations occurs. The paper also presents current views on the origin of the potassium salts and on the possibilities of occurrence of potassium salt deposits, of industrial importance.
