## Mineral - Wikipedia

OverviewDefinitionsRocks, ores, and gemsEtymologyChemistryPhysical propertiesClassificationAstrobiology

In geology and mineralogy, a mineral or mineral species is, broadly speaking, a solid chemical compound with a fairly well-defined chemical composition and a specific crystal structure that occurs naturally in pure form. The geological definition of mineral normally excludes compounds that occur only in living beings. However some minerals are often biogenic (such as calcite) or are organic compoundsin the sense of ch
