To investigate the use of integrated geophysics for the placement of oil shale mines, data were gathered during four field trips to two test sites in the Piceance Creek Basin, Colorado. Seismic, resistivity, audiomagnetotellurics (amt), induced polarization (ip) gravity, and magnetic data were gathered. Available remote sensing data were used for reconnaissance. Landstat data indicated a linear zone that alined with faults found in both test sites. The faults, one of which was confirmed by an observation well, were indicated by resistivity, amt, and closely spaced seismic arrays. With remote sensing for reconnaissance, resistivity or amt, and then closely spaced seismic array are the sequence of geophysical measurements that should be undertaken in this region. For analysis of integrated geophysical data, interactive computer modeling was developed in which seismics, gravity, and resistivity data can be simultaneously simulated.
