Manganese Oxide Deposits Near Butte and Development Since 1942

The manganese minerals occur in the peripheral zone of the Butte district with quartz in veins, which at depth contain galena and sphalerite closely associated with silver-bearing minerals. The manganese oxides are all oxidation products formed by weathering of primary rhodochrosite or rhodonite.

The Psilomelane Mineral of the Butte District, Montana

During the last few years a great deal of research has been done in connection with the black manganese oxide minerals. This is especially true of the so called mineral psilomelane. It has been proven without a doubt that the name psilomelane has been used in the past to include a great variety of similar black manganese oxide minerals. By the use of X-ray equipment these minerals have been definitely identified.
