Popis
As part of a two-year assessment of the geology and mineral resources of the Altiplano and Cordillera Occidental, Bolivia, aeromagnetic and gravity data were acquired from various sources and merged into digital data sets. The data were published as contour mapes (Plates 4 and 5 of Cady and Wise, 1992, USGS) in the final report of the study, USGS Bulletin 1975. The Bolivian Ministry of Mines and Metallurgy recently approved these data for release to the public. In 1991 a new aeromagnetic survey was flown for the Servicio Geologico de Bolivia (GEOBOL) and the Bolivian Ministry of Mines and Metallurgy by BGM Airborne surveys, Inc.
