Title: Ground-magnetic studies of the Amargosa desert region, California and Nevada Publication_Date: 2005 Series_Information: Series_Name: Open-File Report Issue_Identification: 2005-1132 Publication_Information: Publication_Place: Menlo Park, California Publisher: Geological Survey (U.S.) Online_Linkage: http://pubs.usgs.gov/of/2005/1132/ Description: Abstract: Hand-held magnetometer and sample magnetic susceptibility measurements used to help interpret complex patterns in the magnetic anomaly of this area. Purpose: Provide ground-truth information for magnetic anomaly studies designed to determine the cause of low-amplitude aeromagnetic anomalies over Quaternary alluvial deposits in the study area.
