In a 1997 LDRD, Karsten Pruess (Earth Sciences Division, LBNL) and George Brimhall (Geophysics, UC Berkeley) studied and modeled geophysical and geochemical processes that resulted in an ore body of particular interest in the desert of the Andes Mountains in the El Salvador district of Chile. The images presented on this page show a collaboration with the Visualiztion Group. More information.
