Maps showing aeromagnetic data and interpretation for the Kalmiopsis Wilderness, southwestern Oregon Maps showing aeromagnetic data and interpretation for the Kalmiopsis Wilderness, southwestern Oregon
The distinctive magnetic properties of the major rock types in the Kalmiopsis Wilderness of southwestern Oregon facilitate interpretation of aeromagenetic data. The region is composed of tectonic slices of magnetic ultramafic, gabboric, and other ophiolitic rocks faulted against the realitively nonmagnetic Dothan Formation, the equivalent of the Franciscan Complex of Western California...
Maps showing geology and shallow structure of western Rhode Island Sound, Rhode Island Maps showing geology and shallow structure of western Rhode Island Sound, Rhode Island
This report presents the results of a high-resolution, seismic-reflection, and sidescan-sonar survey conducted in western Rhode Island Sound south of Narragansett Bay (fig. 1 inset) by the U.S. Geological Survey in 1980. The study defines the geologic framework of the Atlantic Inner Continental Shelf between lat. 41°09' and 41°32'N and long. 71°07' and 71°37'W. A total of 580 kilometers...
Maps showing mines, quarries, and prospects, with analyses of samples, Gee Creek Wilderness, Polk and Monroe counties, Tennessee Maps showing mines, quarries, and prospects, with analyses of samples, Gee Creek Wilderness, Polk and Monroe counties, Tennessee
This report is part of a series that assesses the mineral potential of the Gee Creek Wilderness (fig. 1). Other reports in the series describe the geology (Epstein, 1983a), geochemistry (Epstein, 1983b), and a summary interpretive report (Epstein, Gazdik, and Behum, 1983). During the recent U.S. Bureau of Mines field investigation, 21 samples were collected (fig. 2) and were submitted to...
