Mineral vs. Kyanite

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 compounds in the sense of chemistry (such as mellite).

Kyanite is a typically blue aluminosilicate mineral, found in aluminium-rich metamorphic pegmatites and sedimentary rock. It is the high pressure polymorph of andalusite and sillimanite, and the presence of kyanite in metamorphic rocks generally indicates metamorphism deep in the Earth's crust.

A naturally occurring, homogeneous inorganic solid substance having a definite chemical composition and characteristic crystalline structure, color, and hardness.

A bluish-green to colorless mineral, Al2SiO5, used as a refractory.

An element, such as gold or silver.

A blue neosilicate mineral, Al₂SiO₅, found in metamorphic rocks.

An organic derivative, such as coal or petroleum.

See Cyanite.

A substance, such as stone, sand, salt, or coal, that is extracted or obtained from the ground or water and used in economic activities.

a gray or greenish-blue mineral consisting of aluminum silicate in crystalline form; occurs in metaphoric rock, used as a refractory

A substance that is neither animal nor vegetable; inorganic matter.

An inorganic element, such as calcium, iron, potassium, sodium, or zinc, that is essential to the nutrition of humans, animals, and plants.

An ore.

minerals Mineral water.

A soft drink.

Of or relating to minerals

Impregnated with minerals.

(geology) Any naturally occurring inorganic material that has a (more or less) definite chemical composition and characteristic physical properties.

Any inorganic material (as distinguished from animal or vegetable).

(nutrition) Any inorganic element that is essential to nutrition; a dietary mineral.

(obsolete) A mine or mineral deposit.

(obsolete) A poisonous or dangerous substance.

of, related to, or containing minerals

An inorganic species or substance occurring in nature, having a definite chemical composition and usually a distinct crystalline form. Rocks, except certain glassy igneous forms, are either simple minerals or aggregates of minerals.

A mine.
