Omphacite is a mineral found in metamorphic rocks, particularly in eclogites. It belongs to the group of clinopyroxene minerals and is known for its unique composition and characteristics.
Composition and Properties
Omphacite is a complex silicate mineral that contains elements such as sodium, calcium, aluminum, iron, and magnesium. Its chemical formula is (Ca,Na)(Mg,Fe,Al)(Si,Al)2O6. Omphacite typically forms elongated crystals with a monoclinic crystal structure.
Formation
Omphacite forms under high-pressure, low-temperature conditions in the Earth's crust or upper mantle. It is commonly found in high-grade metamorphic rocks like eclogites, which are formed from the metamorphism of basaltic rocks at depths of around 30-50 kilometers.
Uses
Omphacite is primarily valuable to geologists as an indicator mineral for studying the geological processes that occur deep within the Earth's crust. Its presence in eclogite rocks provides insights into the tectonic history and geological evolution of specific regions.
Identification
Omphacite is typically identified by its green to greenish-black color, vitreous luster, and cleavage along two distinct planes. Its hardness ranges from 6 to 7 on the Mohs scale, making it a relatively durable mineral.
Omphacite is a key mineral in understanding the formation of eclogites, which are essential components of Earth's geological history.
Geologists rely on the presence of omphacite to decipher the complex processes that shape the Earth's crust over millions of years.
