Additional Information
Title: Shallow Crustal Residual Gravity Anomaly for the Great Basin compiled by Gary Oppliger.
Description: This is a shallow crustal residual calculated by removing broad regional anomaly patterns without regard to source. It emphasizes density changes in the upper few kilometers of the crust, and is best for showing basin patterns. For details, see the geophysics web site of Gary Oppliger at:
http://able1.mines.unr.edu/Geophysics_website/Greatbasin_geophysics1/index.htm
Data Sources:
- National Geodetic Survey (NGS) 1999 gravity database from NGDC Gravity Data 1999 CD-ROM.
- USGS DDS-42 Gravity Map of Nevada Ponce Nevada 1997.
- Recent western Nevada surveys previously compiled by Oppliger 2002.
