Notes

An area of low apparent resistivity values defined by the audiomagnetotelluric (AMT) survey appears to outline the extent of the geothermal reservoir even though the reservoir is deeper than the penetration of the survey. Self-potential anomalies relate to near surface hydrology. Upward leakage from the reservoir produces shallower effects that were measured by the AMT survey.
