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.

Geologic map of the Byrgius Quadrangle of the Moon

The Byrgius quadrangle, at the western edge of the near side, lies in the terra southwest of Oceanus Procellarum between the Humorum and Orientale basins. Structures and deposits related to the Orientale basin, which is younger than the Humorum basin (Hartmann and Kuiper, 1962), dominate the southwestern half of the quadrangle. The northeastern half is dominated by mantling deposits that are older

Geologic map of the Grimaldi quadrangle of the Moon

The Grimaldi quadrangle lies at the southwest margin of Oceanus Procellarum about 1,000 km east of Orientale, the youngest of the lunar multi-ringed basins. The distal ends of the ejecta blanket surrounding the Orientale basin partly covers the western third of the quadrangle. The relatively small, two-ring Grimaldi basin is in the northwest corner of the quadrangle, and the Humorum basin lies abo

Geologic map of the Langrenus Quadrangle of the Moon

The Langrenus quadrangle is on the east limb of the lunar nearside, at the southeast margin of Mare Fecunditatis. The crater Langrenus, about 140 km in diameter, is the most prominent feature. Rugged terra materials, scattered by craters of various sizes and ages, occupy much of the east half of the map area, and smooth mare materials in the Fecunditatis basin dominate the west. Mare Spumans and o

Geologic map of the Petavius quadrangle of the Moon

The large crater Petavius, about 180 km in diameter, is the dominant geologic feature within this quadrangle at the southeast border of Mare Fecunditatis on the east limb of the near side. Four categories of materials have been distinguished herein: (1) terrae, with rugged to gently rolling topography and moderate albedo; (2) plains, of low relief and moderate albedo; (3) craters, with low to rugg

Geologic map of the Phosphate Reserve in the Lander area, Fremont County, Wyoming

The area was mapped as part of the U.S. Geological Survey program of classifying and evaluating lands in the public domain. Resources of economic interest in the map area include oil, gas, water, phosphate rock, gypsum, and analcime. The area mapped includes the rocks between the Tensleep Sandstone and the Morrison Formation and Tertiary and Quaternary deposits.
