Document Summary
Mineral is a naturally occurring homogeneous solid formed by geologic processes with an ordered internal arrangement of atoms, ions, or molecules, and a composition definable by a chemical formula throughout. Naturally occurring - no human made materials. Homologous means that a piece of a mineral contains same pure material. Formed by geographic processes implies processes such as solidification. However, many or precipitation, which did not involve living organisms. geologists now consider solid crystalline materials produced by organisms to be minerals too conditions. minerals. Solids in which atoms occur in random clusters. Definable chemical composition means that the elements present in a. When mineral grows without interference from other minerals, develops smooth. When a mineral grows where other minerals interfere, has an irregular shape but. An irregular or fragmented piece of mineral is a grain. Single piece of a mineral, either crystal or grain, is called a specimen. In geosphere, most minerals occur as parts of rocks.
