Geology of the Lost Creek-Modesty Creek Area Deerlodge County, Montana

In 1915 the United States Geological Survey published a folio by Calkins and Emmons on the geology of the Philipsburg Quadrangle, which ad­joins the area now under study to the west. Geology of this portion of Montana had not been mapped previously; consequently the purpose of this thesis is to make a geological reconnais­sance of the stratigraphy and structure of the area.

Concentration of Manganese Dioxide from Philipsburg, Montana

Imports of manganese ore probably supply a major proportion of the needs of the United States. Domestic production is reported to be higher than pre-war levels, but does not equal that of the peak production year of 1943. In 1946, the Anaconda Copper Mining Company ac­counted for 90 percent of the total shipments of mangan­ese nodules, and this company is the largest producer of domestic metallurgical ore in the United States.

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.
