Potassic-chloro-hastingsite

KCa2(Fe24Fe3⁺)(Si6Al2)O22Cl2
Monoclinic root IMA redefined

Potassic-chloro-hastingsite is a monoclinic amphibole mineral with the chemical formula KCa2(Fe²⁴Fe³)(Si6Al2)O22Cl2. It belongs to the amphibole group within the silicate class and is classified under the Strunz system as 9.DE.15. This mineral exhibits a Mohs hardness of 5, a density typical of amphiboles, and a vitreous luster. It is generally dark in color, reflecting the presence of iron in its structure. Potassic-chloro-hastingsite is distinguished by its potassium and chlorine content, which contribute to its unique chemical composition and classification as a chloro-amphibole.

Overview

Potassic-chloro-hastingsite is a monoclinic amphibole mineral with the chemical formula KCa2(Fe²⁴Fe³)(Si6Al2)O22Cl2. It belongs to the amphibole group within the silicate class and is classified under the Strunz system as 9.DE.15.

Potassic-chloro-hastingsite is distinguished by its potassium and chlorine content, which contribute to its unique chemical composition and classification as a chloro-amphibole.

Etymology

The name 'potassic-chloro-hastingsite' is derived from the presence of potassium and chlorine in its chemical composition, as well as its relationship to the mineral hastingsite. It does not reference a person or place but rather its elemental characteristics.

Geological genesis

As an amphibole, potassic-chloro-hastingsite is likely of igneous or metamorphic origin, commonly forming in environments where silicate-rich magmas or high-grade metamorphic rocks undergo crystallization. Its specific composition suggests formation under conditions involving potassium and chlorine-rich fluids.
