Roscoelite
Roscoelite is a monoclinic phyllosilicate mineral with the chemical formula K(V³⁺,Al)2(AlSi3O10)(OH)2. It is a member of the mica group and is classified under the Strunz system as 9.EC.15. The mineral typically exhibits a vitreous to pearly luster, with a hardness of approximately 2 to 2.5 on the Mohs scale and a specific gravity around 3.0 to 3.2. Roscoelite is usually dark green to black in color and forms in sheet-like structures. It is notable for its layered silicate structure and is commonly found in metamorphic environments.

Overview
Roscoelite is a monoclinic phyllosilicate mineral with the chemical formula K(V³⁺,Al)2(AlSi3O10)(OH)2. It is a member of the mica group and is classified under the Strunz system as 9.EC.15. The mineral typically exhibits a vitreous to pearly luster, with a hardness of approximately 2 to 2.5 on the Mohs scale and a specific gravity around 3.0 to 3.2. Roscoelite is usually dark green to black in color and forms in sheet-like structures. It is notable for its layered silicate structure and is commonly found in metamorphic environments.
Etymology
Roscoelite is named after Henry Enfield Roscoe, a British chemist and mineralogist. The mineral was approved by the International Mineralogical Association (IMA).
Geological genesis
As a phyllosilicate of the mica group, roscoelite typically forms in metamorphic environments where aluminum- and vanadium-rich materials undergo recrystallization under high pressure and temperature conditions.
