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 coal resources of the Honaker Quadrangle, Russell, Tazewell, and Buchanan counties, Virginia Maps showing coal resources of the Honaker Quadrangle, Russell, Tazewell, and Buchanan counties, Virginia
The Honaker quadrangle lies in two physiographic provinces. The northern half of the quadrangle is part of the Appalachian Plateaus province, where the coal-bearing formations of Pennsylvanian age are nearly flat lying or very gently dipping. Diagonally extending east-northeastward across the middle of the quadrangle are several belts of faulted, overturned, and steeply dipping rocks of
Maps showing formation temperatures and configurations of the tops of the Minnelusa Formation and the Madison Limestone, Powder River basin, Wyoming, Montana, and adjacent areas Maps showing formation temperatures and configurations of the tops of the Minnelusa Formation and the Madison Limestone, Powder River basin, Wyoming, Montana, and adjacent areas
This report is part of a study to describe the hydrologic framework needed to evaluate the water resources of the Paleozoic age aquifers in the Northern Great Plains coal region (fig 1). Preliminary studies by the U.S. Geological Survey and State agencies in Wyoming, Montana, and South Dakota have indicated that these aquifers might provide significant percentage of the water...
Maps showing generalized structure contours on the tops of the Wasatch and Green River Formations, geologic sections, and contours of thickness of the Green River Formation, southeastern Uinta Basin, Utah and Colorado Maps showing generalized structure contours on the tops of the Wasatch and Green River Formations, geologic sections, and contours of thickness of the Green River Formation, southeastern Uinta Basin, Utah and Colorado
These maps were prepared as part of a hydrologic investigation in the southeastern Uinta Basin, Utah and Colorado. (See index map.) Most of the study area of 2,350 square miles is underlain by consolidated rocks of Tertiary age – the Wasatch, Green River, and Uinta Formations. The Green River Formation contains thick beds of oil shale, which are of considerable economic importance as a...
Maps showing late Pleistocene and Holocene evolution of the South Texas continental shelf Maps showing late Pleistocene and Holocene evolution of the South Texas continental shelf
Interpretation of acoustical profiles has provided insight into the late Quaternary geologic history of the Continental Shelf off South Texas. (See the geographic index map on sheet 1 for location of the area studied.) The profiles reveal the interplay of tectonism, sedimentation, and cyclic fluctuations of sea level in the building and geologic evolution of the continental terrace. The...
