A geological map has not been completed. However, evaluation of satellite data, known tufa mounds (relic hot springs) and outcrops indicate intra basin structures exist including faults in bedrock outcrop found outside the basin that trend into the Salar.
There are north-south active faults and cross cutting linears that could be cross faulting throughout the basin and adjacent bedrock outcrops.
There are two evident features:
1) the geophysical Zone One appears to be constrained at the north and south ends of the survey area by a significant increase in cross faulting; and
2) the cross faulting appears to dominate the east side of the basin and bedrock complex. These features suggest that conditions may exist to concentrate brines.
