Ferro-ferri-hornblende
Ferro-ferri-hornblende is a complex amphibole mineral with the chemical formula ☐Ca2(Fe^2⁺4Fe^3⁺)(Si7Al)O22(OH)2. It crystallizes in the monoclinic system and belongs to the amphibole group of inosilicates. The mineral is characterized by its prismatic crystal habit and typically exhibits a dark green to black color. It has a vitreous to dull luster, a hardness of approximately 5 to 6 on the Mohs scale, and a specific gravity around 3.0 to 3.4. Its composition reflects the presence of both ferrous (Fe^2⁺) and ferric (Fe^3⁺) iron, distinguishing it from other amphibole varieties.
Overview
Ferro-ferri-hornblende is a complex amphibole mineral with the chemical formula ☐Ca2(Fe^2⁺4Fe^3⁺)(Si7Al)O22(OH)2.

Its composition reflects the presence of both ferrous (Fe^2⁺) and ferric (Fe^3⁺) iron, distinguishing it from other amphibole varieties.
Etymology
The name ferro-ferri-hornblende is derived from the presence of both ferrous (Fe^2⁺) and ferric (Fe^3⁺) iron in its chemical composition.
Geological genesis
As an amphibole, ferro-ferri-hornblende typically forms in igneous and metamorphic environments where conditions favor the crystallization of inosilicate minerals. It is commonly associated with mafic and intermediate rock types.
