Wad & Psilomelane

Wad is a generic name for soft black mostly earthy mass of hydrated manganese oxides, usually containing significant amounts of other metals as iron, nickel, cobalt, copper in form of hydroxides or oxides. Psilomelan is an obsolete group name for hard black manganese oxides. The name wad was used as early miner's term. Interesting occurrence of wad and psilomelan is known from Solnhofen, Germany. Microcrystalline wad (psilomelan) creates "film deposits" on the surface of lithographic shale´s in form of branching aggregates, known as dendrites.
