About AsbolaneHide

Formula:
(Ni,Co)2-xMn4+(O,OH)4 · nH2O
Colour:
Bluish to brownish black
Lustre:
Dull
Crystal System:
Hexagonal
Name:
Named from the Greek "to soil like soot".
A poorly defined material, usually defined as cobalt- or nickel-bearing "wad".

The chemical composition is highly variable and can contain large amounts of Ni, Co, Cu, Mg and other metals. It is a mixed-layer mineral with layers of Mn-O octahedra and of other metals, mostly in separate layers. It should be defined as a group.

A possible Mg analogue is known as UM1995-20-OH:AlMgMnNi.

Varieties of AsbolaneHide

CuproasbolanePresently defined as a Cu-bearing variety of asbolane and a synonym of lampadite.
Can also be considered a cobalt-bearing wad.
Potentially an actual species but requires better definition.

Originally described from Katanga (Shaba), Congo (Zaïre).
