Fundamental Science Practices

USGS provides unbiased, objective, and impartial scientific information upon which our audiences, including resource managers, planners, and other entities, rely.

Learn More

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.

Map showing the distribution of minerals in the heavy-mineral concentrate of stream sediments in the Sierra Ancha Wilderness and Salome Study Area, Gila County, Arizona

Reconnaissance geochemical and mineralogical sampling was done in the Sierra Ancha Wilderness and Salome Study Area during April and May 1978. This map shows the distribution of chalcopyrite, florite, galena, scheelite, and lead-rich iron oxides in the nonmagnetic fraction of the heavy-mineral concentrate of stream sediment samples collected during the reconnaissance study. 

Map showing the Elko crater field, Elko County, Nevada

The Elko crater field consists of two arrays of rimmed craters in the valleys of Dorsey, Susie, and McClellan Creeks, 30 to 50 km north of Elko, Nevada. In the principal array, more the 165 craters are scattered irregularly in an area 3 km wide and 20 km long. Most of the the craters are circular but some, formed by overlap, are oval or irregular. They range from 5 m to 250 m in diameter and the r

Map showing the late preglacial (Teays-age) course and pre-Illinoian deposits of the Licking River in north-central Kentucky

A considerable body of writing exists on the geological evolution of the Ohio River and some of its principal tributaries, among which is the Licking River of Kentucky (fig. 1).

Maps showing aeromagnetic survey and interpretation of the Virgin Mountains Instant Study Area Clark County, Nevada

Data for the aeromagnetic map (fig. 1) of the Virgin Mountains Instant Study Area wre collected in 1978 and compiled at a scale of 1:62,500. North-south traverses were spaced at 0.8-km intervals at an altitude of about 300m above the surface of the ground. The contour interval is 20 and 100 gammas, depending on the steepness of local magnetic gradients in the Earth's magnetic field. A regional fie

Maps showing coal resources of the Crumpler quadrangle, Mercer, McDowell, and Wyoming Counties, West Virginia

Coal GeologyThe Crumpler quadrangle lies in the Appalachian Plateaus province, with the coal bearing Pocahontas and New River Formations of Pennsylvanian age having a gentle dip toward the northwest. Coal bed maps were prepared (figures 1-7) and resources were estimated (table 1) for seven of the many coal beds in the Crumpler quadrangle (Stricker, 1980, lists the names of the various coal beds in

Maps showing coal resources of the Jewell Bridge Quadrangle, Buchanan and Tazewell counties, Virginia

Coal of low-volatile to high-volatile A bituminous rank is the principal developed mineral resource in the Jewell Ridge quadrangle.  The coal beds in the Jewell Ridge quadrangle contain total estimated original resources of 1,519 million tons.  Of this total, 108 million tons have been mined or lost in mining, leaving 1,411 million tons of remaining resources.  Table 1 lists coal resource estimate
