Antigorite

Mg3Si2O5(OH)4
Monoclinic heart IMA redefined

Antigorite is a monoclinic mineral with the chemical formula magnesium trisilicate hydroxide, Mg3Si2O5(OH)4. It belongs to the serpentine group of minerals and is classified under the Strunz system as 9.ED.15. Antigorite typically exhibits a waxy to dull luster, a hardness of approximately 2.5 to 4 on the Mohs scale, and a density ranging from 2.5 to 2.7 g/cm³. It is commonly found in a range of green to greenish-yellow colors. As a hydrous magnesium silicate, it is a product of metamorphic processes involving the alteration of ultramafic rocks.

Overview

Antigorite is a monoclinic mineral with the chemical formula magnesium trisilicate hydroxide, Mg3Si2O5(OH)4. It belongs to the serpentine group of minerals and is classified under the Strunz system as 9.ED.15. Antigorite typically exhibits a waxy to dull luster, a hardness of approximately 2.5 to 4 on the Mohs scale, and a density ranging from 2.5 to 2.7 g/cm³. It is commonly found in a range of green to greenish-yellow colors. As a hydrous magnesium silicate, it is a product of metamorphic processes involving the alteration of ultramafic rocks.

Etymology

Antigorite is named after the Valle Antigorio in the Italian Alps, where it was first described. The IMA has redefined its status, but the origin of its name remains tied to this locality.

Geological genesis

Antigorite forms through metamorphic processes, typically as a result of the hydration and alteration of ultramafic rocks under low-temperature and high-pressure conditions. It is a common member of the serpentine group and is associated with the transformation of minerals such as olivine and pyroxene.

Occurrence

Antigorite is commonly found in regions where ultramafic rocks have undergone serpentinization. Its type locality is the Valle Antigorio in the Italian Alps.
