Preliminary aeromagnetic anomaly map of California

Map showing magnetic anomaly of California composed by merging and editing data from 123 distinct surveys conducted previously.

Info
Gravity map and data of the eastern half of the Big Bear Lake, 100,000 scale quadrangle, California, and analysis of the depths of several basins

Data on the southern portion of the Marine Corps Air Ground Combat Center (MCAGCC) Twentynine Palms and the Yucca Valley-Joshua Tree-Twentynine Palms area and presents the map and basin analyses.

Info
Oregon magnetic and gravity maps and data

Aeromagnetic surveys of Oregon, merged to form seamless grids across the state. Gravity anomaly data are provided as well.

Info
Geophysical data from the Spring and Snake Valleys area, Nevada and Utah

Existing and new gravity station data and magnetometer measurements used to infer geologic structure of this area

Info
Preliminary isostatic gravity map of the Sonoma Volcanic field and vicinity, Sonoma and Napa counties, California

Gravity station data from three separate surveys

Info
Principal facts for gravity stations in the vicinity of San Bernardino, southern California

Gravity measurements collected to help define the characteristics of the Rialto-Colton fault, with rock properties such as lithology, magnetic susceptibility and density.

Info
Modeling of the Climax Stock and related plutons based on the inversion of magnetic data, southwest Nevada

Mathematical modeling, coupled with new observations of magnetic susceptibility, yield better estimates of the underground configuration of granite plutons.

Info
A preliminary investigation of the structure of southern Yucca Flat, Massachusetts Mountain, and CP basin, Nevada Test Site, Nevada, based on geophysical modeling

Maps showing aeromagnetic survey results, locations of gravity station data, and discussions of processing within the report

Info
Geologic and geophysical framework of the Santa Rosa 7.5' quadrangle, Sonoma county, California

Geologic units, structural features, magnetic and gravity anomaly contours and radiometric ages of this area

Info
