A bibliography of some geophysical computer programs, data bases, and maps from the U.S. Geological Survey, 1971-1994
Gravity survey data and a Bouguer gravity anomaly map of the Lost Creek Wilderness and vicinity, Park and Jefferson Counties, Colorado
This report contains digital data, image files, and text files describing data formats for aeromagnetic and gravity data used to compile the State aeromagnetic and gravity maps of Texas.
Principal facts and complete Bouguer gravity map, Blacktail Mountain drilling site, Flathead County, Montana
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 northeast-trending, 200-km-wide zone of spaced negative anomalies, which extends more than 700 km from southwestern Montana's Beaverhead Mountains to the Canadian border and reflects suturing of the Archean Mexican Hat Block against the Archean Wyoming Province along the Paleoproterozoic Trans-Montana Orogen (new name) at about...
This report contains digital data, image files, and text files describing data formats and survey procedures for aeromagnetic data collected during a survey covering the southwestern portion of Taos County west of the Town of Taos, New Mexico, in October, 2006. Several derivative products from these data are also presented as grids and images, including reduced-to-pole data and data continued to a reference surface. Images are presented in various formats and are intended to be used as input to geographic information systems, standard graphics software, or map plotting packages.
Aeromagnetic interpretations for understanding the hydrogeologic framework of the southern Espanola Basin, New Mexico
Complete Bouguer gravity anomaly map of the Uinta and Piceance basins and vicinity, Utah and Colorado
Mineral resource potential and geology of the Routt National Forest and the Middle Park Ranger District of the Arapaho National Forest, Colorado
The assessment of the mineral resource potential of the Routt National Forest and the Middle Park Ranger District of the Arapaho National Forest, Colorado, was conducted so that the mineral resources of the forest can be considered along with other resources in land use planning. This report discusses the potential for as yet undiscovered mineral and energy resources within the forest. Mineral resource information is given in terms of mineral deposit types and their geologic settings, and mineral deposit types are defined by geologic characteristics of known deposits that may occur within or near the forest. All available information regarding mineral deposits or occurrences and energy resources, as of June 1994,...
This report contains digital data, image files, and text files describing data formats for aeromagnetic and gravity data used to compile the State aeromagnetic and gravity maps of Arkansas and Louisiana. The digital files include grids, images, ArcInfo, and Geosoft compatible files. In some of the data folders, ASCII files with the extension 'txt' describe the format and contents of the data files. Read the 'txt' files before using the data files.
