Description:
Abstract:
This field was calculated by estimating the effect caused by variations in thickness of Cenozoic deposits on the observed isostatic residual gravity field, then removing it to derive a basement isostatic residual gravity field.
Purpose: For geologic, mineral, or geothermal exploration
Supplemental_Information:
ESRI real number GRID format, cell size 500 m, 1548 rows, 1046 columns. For details on theory behind grid construction, see Jachens, R.C., Moring, B.C., and Schruben, P.G., 1996, Thickness of Cenozoic deposits and the isostatic residual gravity over basement (Chapter 2), in Singer, D.A., ed., An analysis of Nevada's metal bearing mineral resources: Nevada Bureau of Mines and Geology Open-File Report 96-2.
