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.

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. |
