Abstract The analyzed 32 sylvinitic rocks contain up to 3 wt.% water-insoluble residues. The most common minerals are illite, quartz and chlorite. Magnesite occurs as a common minor compound. High MgO-contents of 12 to 19 % account for the presence of further non identified minerals such as talc or koenenite. The distribution of rare-earth elements does not seem to be affected to a great extent by the presence of brines, whereas significant differences in the contents of main components (Na, K, Ca, Mg) in shales, "Salzton" and water-insoluble residues of sylvinitic rocks are noticed. The mineral reactions caused due to the presence of brines seem to be related to the composition of the interacting brine.
