Geology, geochemistry and petrological characteristics of potash salt units from PZ2 and PZ3 Zechstein (Late Permian) cycles in Poland

Abstract

Analysis of archive and published geological, geochemical and petrological data on composition of potash-bearing units (Older Potash [K2] and Younger Potash [K3]) of the Polish Zechstein (Late Permian) sections (mainly sampled pro les form three salt diapirs located in central Poland: Gra, K odawa, Mogilno, and additionally for petrology from Inowroc aw diapir as well as some data from the stratiform potash occurrences in the Foresudetic area in SW Poland) enabled to de ne content intervals and data statistic of main chemical components of both potash units as well as a type and content of determined evaporate minerals composed them.
