kieserite [′kē·zə‚rīt]
(mineralogy) MgSO4·H2O A white mineral that crystallizes in the monoclinic system, is composed of hydrous magnesium sulfate, and occurs in saline residues. Kieserite (after the German scientist D. G. Kieser, 1779–1856), a mineral of the sulfate class, chemical composition, Mg[SO4] · H2O, containing 29.0 percent MgO. Kieserite crystallizes in the monoclinic system. Crystals are rare; compact fine-grained aggregates are more usual. Kieserite is milky white, sometimes yellowish, in color. Its hardness is 3.5 on the mineralogical scale; its density, 2,570 kg per cu m. The mineral is brittle and readily soluble in water. The taste is bitter. Kieserite is a typical mineral in fossil salt deposits (more rarely, in modern salt-lake sediments), where it is formed chiefly as a result of the metamorphism and dehydration of the mineral epsomite. Kieserite is used, along with other magnesium sulfates, in the chemical, textile, and paper industries and in medicine. Want to thank TFD for its existence?
