Gypsum is a common mineral, with thick and extensive evaporite beds in association with sedimentary rocks. Deposits are known to occur in strata from as far back as the Archaean eon. Gypsum is deposited from lake and sea water, as well as in hot springs, from volcanic vapors, and sulfate solutions in veins.
In geology and mineralogy, a mineral or mineral species is, broadly speaking, a solid substance with a fairly well-defined chemical composition and a specific crystal structure that occurs naturally in pure form. [1] [2] The geological definition of mineral normally excludes compounds that occur only in living organisms.

Granite. Granite ( / ˈɡrænɪt / GRAN-it) is a coarse-grained ( phaneritic) intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground.
Jasper, an aggregate of microgranular quartz and/or cryptocrystalline chalcedony and other mineral phases, [1] [2] is an opaque, [3] impure variety of silica, usually red, yellow, brown or green in color; and rarely blue. The common red color is due to iron (III) inclusions. Jasper breaks with a smooth surface and is used for ornamentation or ...
In the context of nutrition, a mineral is a chemical element. Some "minerals" are essential for life, most are not. [1] [2] [3] Minerals are one of the four groups of essential nutrients, the others of which are vitamins, essential fatty acids, and essential amino acids. [4] The five major minerals in the human body are calcium, phosphorus ...
Metallic minerals. Metallic minerals are the minerals which contain one or more metallic elements. They occur in rare, naturally formed concentrations known as mineral deposits. Metallic minerals available in India are gold, cobalt, zinc, iron ore, manganese ore, bauxite, silver, lead, tin, copper and chromite. Chromite
