Fundamental Science Practices
USGS provides unbiased, objective, and impartial scientific information upon which our audiences, including resource managers, planners, and other entities, rely.
USGS provides unbiased, objective, and impartial scientific information upon which our audiences, including resource managers, planners, and other entities, rely.
Our programs produce accurate geologic maps and 3-D geologic frameworks that provide critical data for sustaining and improving the quality of life and economic vitality of the Nation. They also organize, maintain, and publish the geospatial baseline of the Nation's topography, natural landscape, built environment and more.

Maps showing distribution of zinc in heavy-mineral concentrates, Richfield 1° by 2° quadrangle, Utah Maps showing distribution of zinc in heavy-mineral concentrates, Richfield 1° by 2° quadrangle, Utah
These maps are part of a folio of maps of the Richfield 1° x 2° quadrangle, Utah, prepared under the Coterminous United States Mineral Assessment Program. Other publications in this folio are listed in the selected references. Located in west-central Utah, the Richfield quadrangle covers the eastern part of the Plioche-Marysvale igneous mineral belt, which extends from the vicinity of...
Maps showing mines, prospects, and mineral sites in the Tray Mountain Roadless Area and vicinity, Northern Georgia Maps showing mines, prospects, and mineral sites in the Tray Mountain Roadless Area and vicinity, Northern Georgia
The Tray Mountain Roadless Area, a 36,300-acre tract in the Chattahoochee National Forest, northeastern Georgia, lies within the Blue Redge physiographic province. The roadless area is composed of Precambrian(?)-age metamorphic rocks from two tectonic units, the Hayesville thrust sheet and the "Helen belt" (Nelson, 1982) (fig. 1). The Hayesville thrust sheet consists mostly of biotite...
Maps showing sea-floor topography, depth to bedrock, and sediment thickness, Penobscot Bay, Maine Maps showing sea-floor topography, depth to bedrock, and sediment thickness, Penobscot Bay, Maine
This report presents results of a high-resolution seismic-reflection survey conducted by the U.S. Geological Survey to determine the subbottom characteristics of Penobscot Bay, Maine. Penobscot Bay is one of the major embayments along the U.S. Atlantic coast (fig. 1), extending more than 50 km from the Gulf of Maine to the mouth of the Penobscot River. The bay constitutes an area of...
Maps showing selected geology and phosphate resources of the Harrington Peak quadrangle, Bear Lake and Caribou Counties, Idaho Maps showing selected geology and phosphate resources of the Harrington Peak quadrangle, Bear Lake and Caribou Counties, Idaho
This report summarizes information on the thickness, grade, lateral continuity, phosphate resources, and ownership of phosphate-bearing units in the Meade Park Phosphatic Shale Member of the Phosphoria Formation in the Harrington Peak quadrangle. This report is one of a series of quadrangle reports prepared by the Idaho Bureau of Mines and Geology under U.S. Geological Survey cost...

Maps showing water geochemistry of the Buffalo Peaks Wilderness Study Area, Lake, Park, and Chaffee Counties, Colorado Maps showing water geochemistry of the Buffalo Peaks Wilderness Study Area, Lake, Park, and Chaffee Counties, Colorado
This report presents results of geochemical studies carried out in June and July of 1982 in the Buffalo Peaks Wilderness Study Area, Colo. (see index map). Samples of water were collected from 84 streams and 18 springs draining the study area. Tabulations of the analyses and a sample locality map are in Ficklin and others (1984). The geochemistry of stream sediments and panned...
