Gypsum crystals nucleate on existing gypsum crystals and surfaces of clay minerals. The transformation of anhydrite into gypsum proceeds until all the anhydrite present in the rock is converted to gypsum. This process (gypsification of anhydrite) is accompanied by about 61% increase in volume (Butscher et al. 2011, 2017; Jarzyna et …

Gradual variation of anhydrite content between laminae suggests that sulfate crystals formed in the water column (probably as gypsum, but now replaced by anhydrite) and then rained down on the sea floor forming a crystal cumulate (Fig. 7 B), similar to the Permian Castile Formation (cf. Anderson et al., 1972). In the Ara Group, sulfate beds ...

We investigate why the sulphatic claystones of the Gypsum Keuper contain anhydrite rather than gypsum even at small depths of cover. This question is relevant due to the phenomenon of swelling of anhydritic claystones, which is attributed to the transformation of anhydrite into gypsum and has caused serious damage to a …
