Applied Mineralogy in the Mining Industry
It occurs as aggregates of crystals associated and intergrown with hematite, Mn-
goethite, psilomelane and wad. Some is present in interstices between hematite
and magnetite, and some as veinlets in Mn-goethite. 8.2.2.6.2. Psilomelane (Mn ...

Tungsten Mineralization in the United States
With this in mind the name tungomelane was suggested for the tungsten-bearing
member of the psilomelane group. Fleischer and Richmond (1943) have
separated the psilomelane group into the supposedly tetragonal, potassium-rich

The Oceanic Lithosphere
Psilomelane also has cation exchange properties and requires some of the
manganese to be in oxidation states lower than Mn(IV) in order to balance the
charge of the exchangeable large cations (Ba2+, K+). The psilomelane structure
differs ...

Usually psilomelane and lithiophorite occur as finely ¡ntergrown crystals about l /
im in diameter. Admixtures of these minerals with clay give grey-brown masses
under the microscope, too soft to polish. Cryptomelane may also exist in these ...
