Blatterite - Occurrence, Properties, and Distribution

Blatterite is an orthorhombic-dipyramidal black mineral, which is composed of oxygen, manganese, magnesium, iron, boron, and antimony. It is a member of the orthopinakiolite group.

The mineral was named after Fritz Blatter, a German mineral collector, who discovered it from the Kittel mine, Varmland, Sweden.

How to Identify Blatterite

Blatterite is black in color, with a brown streak and sub-metallic luster. It has prismatic crystals, perfect cleavages, and opaque characteristics.

The hardness of the mineral is 6, and its density is 4.7 g/cm3.

Global Distribution

Blatterite is largely distributed at Nordmark, and at Langban, Varmland, Sweden.

Occurrence of Blatterite and Useful Mineral Association

Blatterite occurs in metamorphosed Fe–Mn orebodies.

Calcite, katoptrite, hausmannite, pyrochroite, and manganosite are all closely associated with blatterite.
