Maps showing locations and descriptions of radiocarbon-dated samples from central and northern California Maps showing locations and descriptions of radiocarbon-dated samples from central and northern California
This compilation includes radiocarbon dates and other pertinent information about samples from northern and central California, principally north of latitude 36°, drawn largely from Radiocarbon, Science, unpublished data of U.S. Geological Survey geologists, and other published and unpublished data brought to the author's attention as of January 1981. It includes a location map, several...
Maps showing mines, quarries, oil and gas activity, and sample localities in and near the Sipsey Wilderness and additions, Lawrence and Winston counties, Alabama Maps showing mines, quarries, oil and gas activity, and sample localities in and near the Sipsey Wilderness and additions, Lawrence and Winston counties, Alabama
The U.S. Bureau of Mines conducted a field reconnaissance of Sipsey Wilderness in the fall of 1978 and of the roadless areas in the spring and summer of 1979. Mines, quarries, prospects, exposures, and drill sites in and near the study area were examined. Fifty-three samples were collected during the field work; sample localities are shown in figure 3. Analyses and preliminary test...
Maps showing uranium-bearing diatremes of the Hopi Buttes, Arizona Maps showing uranium-bearing diatremes of the Hopi Buttes, Arizona
The Hopi Buttes dominate the landscape north of Holbrook, Arizona, commonly rising to heights of 180 m above the surrounding countryside. The buttes are underlain by individual diatremes, or in some cases by a complex of diatremes. Some sediment-filled diatremes also crop out as inconspicuous low hills (some may also be buried beneath the alluvium). The diatremes erupted into the late...
Metalliferous mineral resource potential of the Seward and Blying Sound quadrangles, southern Alaska Metalliferous mineral resource potential of the Seward and Blying Sound quadrangles, southern Alaska
This mineral potential map is the final report in a series of publications that makes up a folio on the Seward and Blying Sound quadrangles of southern Alaska. It draws on data largely presented in previous publications of the folio. The studies were undertaken as part of the Alaska Mineral Resource Assessment Program (AMRAP), a program designed to provide information for Federal, State...
Mine and prospect map of the Pusch Ridge Wilderness Area, Pima County, Arizona Mine and prospect map of the Pusch Ridge Wilderness Area, Pima County, Arizona
The Endangered American Wilderness Act of 1978 created the Pusch Ridge Wilderness. During 1979, the U.S. Geological Survey and the U.S. Bureau of Mines investigated the area to evaluate the mineral resources. In addition to field investigations, studies by the Bureau of Mines personnel included courthouse research to ascertain claim locations within and near the area. Field work involved
Mineral resource potential map of Hercules Glades Wilderness, Taney County, Missouri Mineral resource potential map of Hercules Glades Wilderness, Taney County, Missouri
Under the provisions of the Wilderness Act (Public Law 88-577, Sept. 3, 1964) and the Joint Conference Report on Senate Bill 4, 88th Congress, the U.S. Geological Survey and the U.S. Bureau of Mines have been conducting mineral surveys of wilderness and primitive areas. Areas officially designated as "wilderness," "wild," or "canoe" when the act was passed were incorporated into the...

Mineral resource potential map of the Bighorn Mountains Wilderness Study Area (CDCA-217), San Bernardino County, California Mineral resource potential map of the Bighorn Mountains Wilderness Study Area (CDCA-217), San Bernardino County, California
Geological, geochemical, and geophysical evidence, together with a review of historical mining and prospecting activities, suggests that most of the Bighorn Mountains Wilderness Study Area has low potential for the discovery of all types of mineral and energy resources-including precious and base metals, building stone and aggregate, fossil fuels, radioactive-mineral resources, and...
