Karst as a type of landscape found on carbonate rocks (limestone, dolomite, marble) or evaporites (gypsum, anhydrite, rock salt) is characterized by a suite of landforms comprising springs, dolines, caves, collapsed sinkholes and carbonate depositional landforms [1,2,3].This karst landscape type is well developed in the coastal area near the city of Safi in West Morocco ().

Anhydrite gypsum is the more concentrated version of calcium sulfate. Gypsum is a fast-release material, anhydrite gypsum a slower-release product which stays in the root zone longer making it available for plant uptake. The true cost of any particular calcium sulfate application may, ultimately, depend on its shipping cost.

Lithology and rock type determination - PetroWiki

Although associated with gypsum, anhydrite lacks H 2O molecules. Anhydrite closely resembles gypsum in hand samples, but it has three cleavage planes at 90 degree angles. In addition, anhydrite is slightly harder and denser compared with gypsum and may have a bluish tint. Both gypsum and anhydrite are used as soil additives and in portland cement.
