Abstract

The paper gives a quantitative description of the chemical reactions, the dissolution and precipitation processes which take place when water or brines come into contact with the main mineral assemblages of the German Zechstein salt formation, rock salt with Ca-sulfates, and the potash beds hartsalz and carnallitite. The results of two large scale in situ dissolution tests are presented. These results have been successfully reproduced by computer modelling using the geochemical code EQ3/6.
