Gypsum -- A widely distributed mineral consisting of hydrous calcium sulfate: CaSO 4- H 2 O. It is closely related to structural geology, but tectonics generally deals with larger features. Four kinds may be distinguished: (1) polar deserts, marked by perpetual snow cover and intense cold; (2) middle-latitude deserts, in the basinlike interiors of the continents, such as the Gobi, characterized by scant rainfall and high summer temperatures; (3) trade-wind deserts, notably the Sahara, with negligible precipitation and large daily temperature range; (4) coastal deserts, as in Peru, where there is a cold current on the western coast of a large land mass.
