Manganese (Inventory)/Crust
From LagWiki
The Crust field of the Manganese section should list stations where a crust of manganese is found.
A manganese crust is a thin layer of manganese that is not firmly adhered to the substructure. It can be recognized by its dark, almost black coloring. It should not be confused with calcite that has been stained black by manganese. Moist manganese crusts often come off when touched so great care should be taken not to disturb them. They can be found on bedrock or clays.
