Surficial geologic map of the Northeast Memphis quadrangle, Shelby County, Tennessee
The depiction of geology on this map is designed to aid in urban planning and analysis of potential damage in the event of strong earthquake motion. The geologic map by itself does not analyze potential earthquake damage, but is designed to be used by seismologists who perform such analyses. The nature of geologic materials to a degree determines the severity of damage to infrastructure sustaine
Surficial geologic map of the Northwest Memphis quadrangle, Shelby County, Tennessee, and Crittenden County, Arkansas
The depiction of geology on this map is designed to aid in urban planning and analysis of potential damage in the event of strong earthquake motion. The geologic map by itself does not analyze potential earthquake damage, but is designed to be used by seismologists who perform such analyses. The nature of geologic materials to a degree determines the severity of damage to infrastructure sus
Geologic and Fossil Locality Maps of the West-Central Part of the Howard Pass Quadrangle and Part of the Adjacent Misheguk Mountain Quadrangle, Western Brooks Range, Alaska
The map depicts the field distribution and contact relations between stratigraphic units, the tectonic relations between major stratigraphic sequences, and the detailed internal structure of these sequences. The stratigraphic sequences formed in a variety of continental margin depositional environments, and subsequently underwent a complexde formational history of imbricate thrust faulting
Geologic insights and suggestions on mineral potential based on analyses of geophysical data for the southern Toquima Range, Nye County, Nevada
Aeromagnetic and gravity data provide confirmation of major structural and lithologic units in the southern Toquima Range, Nevada. These units include Cretaceous granite plutons and Tertiary calderas. In addition, the geophysical maps pinpoint numerous faults and lesser intrusions, and they suggest locations of several inferred subsurface intrusions. They also corroborate a system of northwesterly

Geologic map of south-central Yucca Mountain, Nye County, Nevada
New 1:6,000-scale geologic mapping in a 20-square-kilometer area near the south end of Yucca Mountain, Nevada, which is the proposed site of an underground repository for the storage of high-level radioactive wastes, substantially supplements the stratigraphic and structural data obtained from earlier, 1:24,000-scale mapping. Principal observations and interpretations resulting from the lar
Precambrian basement geologic map of Montana– An interpretation of aeromagnetic anomalies
Newly compiled aeromagnetic anomaly data of Montana, in conjunction with the known geologic framework of basement rocks, have been combined to produce a new interpretive geologic basement map of Montana. Crystalline basement rocks compose the basement, but are exposed only in the cores of mountain ranges in southwestern Montana. Principal features deduced from the map are: (1) A prominent north
Surficial geologic map of the southeast Memphis Quadrangle, Shelby County, Tennessee
The depiction of geology on this map is designed to aid in urban planning and analysis of potential damage in the event of strong earthquake motion. The geologic map by itself does not analyze potential earthquake damage, but is designed to be used by seismologists who perform such analyses. Wind-deposited silt and clayey silt (loess) is the predominant surficial deposit. Loess entirely c
Surficial geologic map of the southwest Memphis Quadrangle, Shelby County, Tennessee, and Crittenden County, Arkansas
This map is one of seven 1:24,000-scale (7.5-minute) quadrangle maps of the surficial geology of the Memphis, Tennessee, area--part of a series of urban hazard maps. Wind-deposited silt and clayey silt (loess) is the predominant surficial deposit in this quadrangle. The loess was deposited as dust during the last major continental glaciation of the region and it covers the upland to
Topographic Map of the Northeast Ascraeus Mons Region of Mars - MTM 500k 15/257E OMKT
This map is part of a series of topographic maps of areas of special scientific interest on Mars. The topography was compiled photogrammetically using Viking Orbiter stereo image pairs. The contour interval is 250 meters. Horizontal and vertical control was established using the USGS Mars Digital Image Model 2.0 (MDIM 2.0) and data from the Mars Orbiter Laser Altimeter (MOLA).
