Köppen climate type:


Small lenses of anhydrite and gypsum also crop out near the base of the slope at Sar-e-Sang. These are probably remnants of geosynclinal, Archean-age evaporite beds (halite, anhydrite, gypsum).

There is more than one of these deposits, especially the brecciated crystals with rehealed broken ends in gypsum. These are gypsum diapirs. Due to the lower density of gypsum, it forces its way up through veins breaking off and digesting crystals from the vein walls. Those have been attributed to Rakhui, Fargon Meeru, and Pitwak. See Marialite photos.
