Notes
Interpretation of seismic refraction recordings in the area yielded compressional velocities from near the surface to the crystalline basement at a maximum depth of approximately 1600 m. The results show a complex sequence of sediments and volcanic flows overlying basement. Velocities in the sedimentary section vary laterally. Correlation with well data suggests that zones of higher velocities may correspond to zones where sediments are hydrothermally altered. Flowing hot wells occur near the boundary between inferred shallow altered and unaltered rocks.
