A mineral is a natural inorganic solid with a defined chemical composition and crystal structure. In geology, a mineral is a naturally occurring solid that has a well-defined chemical composition and crystal structure. Most minerals are inorganic, although some mineralogists allow for minerals that are organic compounds or else made by …

A mineral is a naturally occurring, inorganic solid substance that has a specific chemical composition and a crystalline structure. Minerals are the building blocks of rocks, which are made up of one or more minerals. They are typically formed through various geological processes, such as crystallization from a melt (igneous), precipitation ...
