Gravity Map of Nevada

by David A. Ponce



Gordon P. Eaton, Director


This publication consists of a report presented in Acrobat PDF format (560 KB), a large gravity-station-location map (PDF; 3.1 MB), and a data directory (12 MB).

Gravity data for the entire state of Nevada and adjacent parts of California, Utah, and Arizona are available on CD-ROM (see "Availability" below) and on this Web site (see Data Files, below). About 80,000 gravity stations were compiled primarily from the National Geophysical Data Center and the U.S. Geological Survey. Gravity data were reduced to the Geodetic Reference System of 1967 and adjusted to the International Gravity Standardization Net 1971 gravity datum. Data were processed to complete Bouguer and isostatic gravity anomalies by applying standard gravity corrections including terrain corrections and isostatic corrections. A 1_README.TXT (see below) file describes the contents of the CD-ROM and includes a description of the data reduction process, selected principal fact references, and a list of sources for data from the National Geophysical Data Center.

To view this report, which is in PDF format, you will need Adobe Reader.

Data Files

Data are organized into 19 files, one for each of the 18 1 X 2 degree quadrangles that cover Nevada as well as a single file containing all the data. You can download any of the 19 data files from the /DATA folder. These file names end in .iso.txt (for "isostatic") and are ASCII files

You can also download all of the data at once in a compressed .zip file (DDS_42_DATA.zip; 4.2 MB). The 19 files in this archive have the .txt file extension added.
