Dalnegorskite

Ca5Mn(Si3O9)2
Triclinic IMA approved

Dalnegorskite is a rare mineral with the chemical formula calcium pentasilicate of manganese. It belongs to the triclinic crystal system, which is characterized by three axes of unequal length and all angles oblique. This mineral is part of the inosilicate class, a group of silicates where silicon-oxygen chains form the structural basis. Dalnegorskite typically exhibits a vitreous luster and is known for its relatively high density. Its physical properties, such as hardness and color, are not explicitly detailed in the available facts, but its classification suggests it is a complex silicate mineral formed under specific geological conditions.
