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.
