    Veins Gypsum veins are of the variety often known as selenite, in which the gypsum is crystalline and glassy, occasionally taking a finely columnar form, known as satin spar Such veins are formed by the solution of gypsum from the surrounding rocks or from other deposits, the material being reprecipitated in cracks through the rocksBorates are mined in southern California Gypsum, a compound of calcium, sulfur, and oxygen, forms when salt water evaporates It also forms when sulfurrichCalifornia Geology Facts Mineral Processing & MetallurgyGypsum Gypsum is a common mineral obtained from surface and underground deposits It can be a valuable source of both calcium (Ca) and sulfur (S) for plants and may provide benefits for soil properties in specific conditions Production Gypsum is found in both crystal and rock formsGypsum No 16

  • Gypsum: a review of its role in the deterioration of

    The deterioration of buildings and monuments by gypsum is the result of crystallization cycles of this salt Although gypsum can dehydrate to a hemihydrate, the mineral bassanite, and to an anhydrate, the mineral anhydrite, this reaction occurs in nature on a geological time scale and therefore it is unlikely to occur when gypsum is found on and in building materials The CaSO4–H2O systemGypsum Gypsum is a mineral consisting of watercontaining calcium sulphate (CaSO 4 2 H 2 O) When calcined (roasted) at temperatures of 120250°C, gypsum releases 75% of its water The resulting plaster of Paris, when mixed with water, can be molded, shaped or spread, then dried or set to form hard plasterGypsum | The Canadian Encyclopedia
