The Arlington copper mine: North Arlington, New Jersey

The Arlington copper mine is located in North Arlington, Bergen Co., N. J. The ore deposit occurs in a 10- to 30-foot thick arkosic sandstone layer, interbedded in red shale. Copper mineralization is associated with thin diabase sills and dikes. It would probably not be feasible to develop the underground workings since they are overlain by the residential section of North Arlington. One area, containing approximately 11,000 tons of indicated ore could possibly be quarried.

Summary of the Midway and Wilcox stratigraphy of Alabama and Mississippi

This study of the stratigraphy of the Midway and Wilcox groups of Alabama and Mississippi was part of the extensive bauxite investigations carried on by the Geological Survey and the Bureau of 'lines of the United States Department of the Interior in 19112 and 1943. The stratigraphic study was undertaken to determine in what formation or formations the bauxite deposits occur, under what paleogeographic conditions the bauxite-bearing formations were deposited, and when and under what conditions the bauxite was formed.

Manganese, iron, and barite deposits of the James River-Roanoke River district, Virginia

During the period 1940-1942 the United States Geological Survey made a geologic study of the manganese deposits of the James River-Roanoke River district, in the general vicinity of Lynchburg, Va. (fig. 1), as part of its program of strategic minerals investigations. This work was done by the writer and supervised by D. F. Hewett. John Rodgers and W. R. Wagner assisted during part of the project. In the course of the investigation, the geology was mapped over an area about 60 miles long and several miles wide, from Altavista on the Roanoke River northeast to Howardsville on the James River (fig. 2); and the mineral deposits-principally manganese, iron, and barite-were studied. After completion of the geologic studies, the writer participated in an exploration project conducted by the United States Bureau of Mines in the early summer of 1942 at five manganese deposits in the district. This preliminary report presents the essential information concerning the mineral deposits of the region in advance of the more comprehensive report on the geology and mineral deposits that will be published as a bulletin of the U.S. Geological Survey.
