Gehlenite

Ca2Al(SiAl)O7
Tetragonal root IMA grandfathered

Gehlenite is a calcium aluminum silicate mineral with the chemical formula Ca2Al(SiAl)O7. It crystallizes in the tetragonal crystal system and belongs to the sorosilicate class of minerals, specifically classified under Strunz category 9.BB.10 and Dana number 55.4.1.2. This mineral typically exhibits a dull to subvitreous luster and is commonly found in a grayish to brownish color. It has a hardness of approximately 6 to 6.5 on the Mohs scale and a relatively high density. Gehlenite is notable for its role in metamorphic and igneous rock formations, where it often forms under high-pressure and high-temperature conditions.

Overview

Gehlenite is a calcium aluminum silicate mineral with the chemical formula Ca2Al(SiAl)O7. It crystallizes in the tetragonal crystal system and belongs to the sorosilicate class of minerals, specifically classified under Strunz category 9.BB.10 and Dana number 55.4.1.2. This mineral typically exhibits a dull to subvitreous luster and is commonly found in a grayish to brownish color. It has a hardness of approximately 6 to 6.5 on the Mohs scale and a relatively high density. Gehlenite is notable for its role in metamorphic and igneous rock formations, where it often forms under high-pressure and high-temperature conditions.

Etymology

Gehlenite is named after Adolf Ferdinand Gehlen, a German mineralogist who made significant contributions to the field of mineralogy.

Geological genesis

Gehlenite is typically of metamorphic origin, forming in high-pressure and high-temperature environments such as those found in regional metamorphic zones. It is commonly associated with calcium-rich and aluminum-rich conditions, making it a characteristic mineral in certain types of metamorphic rocks.
