Nevada Isostatic Residual Gravity Over Basement
This study of gravity data from Nevada is part of a statewide analysis of mineral resources. The main objective of the gravity study were: 1) to infer the structure and composition of the basement; 2) to determine the thickness of Cenozoic deposits. An iterative procedure based on the gravity data, a knowledge of the surface geology, and an estimate of the density of Cenozoic deposits was used to separate the isostatic residual gravity field into two component parts, a "basement" component and a "cover thickness" component. The former component contains information about the basement whereas the latter yields an estimate of the thickness of Cenozoic deposits. All computations were performed with a rectangular grid having intersections spaced at 2 km. The results are presented as contours on two maps at a scale of 1:1,000,000. Sheet 1 represents the basement gravity and sheet 2 represents the inferred thickness of Cenozoic cover. For complete details see Open File Report 90-404.

Supplemental Information | In addition to giving the Bounding Coordinates in latitude and longitude, the limits of coverage for the gridded and projected data sets are also given in units of measure of the projection. This is usually the distance from a central meridian (the x-coordinate), or base latitude (the y-coordinate), in meters or kilometers of the given projection. For this data set those boundaries are:The Western-most boundary: -262.898 kilometersThe Eastern-most boundary: 273.102 kilometersThe Northern-most boundary: 4963.07 kilometersThe Southern-most boundary: 4177.07 kilometers |
Purpose | To provide easy access to global and regional gravity data and related models for scientific studies. |
