Mineral resource potential map of the Clear Lake Roadless Area, Leon County, Florida
Charles W. Hendry Jr., Sam H. Patterson, Thomas M. Crandall, John W. Sweeney
1982, Miscellaneous Field Studies Map 1479
The only mineral material that has been produced within the Clear Lake Roadless Area is clayey sand used as fill for highway construction and for stabilizing Forest Service roads. Fuller's earth, common clay, and sand and gravel presently are produced in Leon County and in nearby counties, and limestone and...
Mineral resource potential map of the Vermilion Cliffs-Paria Canyon instant study area, Coconino County, Arizona, and Kane County, Utah
Alfred L. Bush, Michael Lane
1982, Miscellaneous Field Studies Map 1475-D
In general, the mineral potential of the study area is low; in the past the area has yielded only several hundred tons of uranium ore, and there have been a number of unsuccessful efforts to produce gold. The generally small uraniferous deposits are in the Chinle Formation, mostly in the basal...
Maps and interpretation of geochemical anomalies in the John Muir Wilderness, Fresno, Inyo, Madera and Mono counties, California
David A. Dellinger, Michael F. Diggles, E. A. Du Bray (compiler)
1982, Miscellaneous Field Studies Map 1185-B
A geochemical survey of the John Muir Wilderness was conducted by the U.S. Geological Survey between 1969 and 1978.  The 755-mi2 (1,956-km2) wilderness is located in the central Sierra Nevada, Calif. (fig. 1). Stream-sediment samples were collected at 1,434 sites in the wilderness and...
Mineral resource potential map of the Gila-San Francisco Wilderness Study Area, Graham and Greenlee counties, Arizona
Donlad H. Richter, Douglas P. Klein, Viki A. Lawrence, Michael Lane
1982, Miscellaneous Field Studies Map 1315-B
The mineral resource potential of the Gila-San Francisco Wilderness Study Area (AZ-040-022/023/024) is low (fig. 2). Although favorable geologic environments for placer gold deposits and manganese vein deposits are present in the study area, the probability of discovering economically exploitable deposits of these metals is low, and not encouraging. Even...
Photographs of the Upper Pleistocene section at Sankaty Head cliff, Nantucket Island, Massachusetts
Robert N. Oldale
1982, Miscellaneous Field Studies Map 1397
The pre-Sangamonian and Wisconsinan glacial drift units and Sangamonian marine beds exposed tin the Sankaty Head cliff (fig. 1) constitute a unique and important upper Pleistocene stratigraphic section in southern New England. Many workers have studied the section over the past 130 years, paying most attention to the fossiliferous Sankaty...
