A seismic reflection survey using the ''Vibroseis'' technique and a combination of both compressional and horizontally polarized shear waves has been successfully completed over the East Mesa Geothermal Field. The interpreted results of the survey demonstrate that: (1) The compressional waves have the resolving power to detect anomalous conditions such as faults and fracture zones of critical importance in geothermal reservoir investigations. (2) The shear waves have penetrated to the target depth but the lower quality of the data, thus acquired renders its processing and interpretation more difficult and less reliable. However, it also contains information which may prove essential for lithological discrimination, such as estimating the ratio V/sub P//V /sub S/ of the velocities.
