Abstract
The thermal seepages at Hot Water Beach discharge an uncontaminated, neutral pH NaC1-type water (TDS c. 4gJkg) at a max. temperature of 64?C (estimated heat discharge is between 0.3 and 1 MW). The reservoir is contained within a NNE trending fracture zone of unknown width. Cation geothermometers point to deep fluid temperatures of up to 170?C; cooling upper crustal rocks are the likely heat source and temperatures in deep wells indicate a sweep depth of up to 2 km for any advective flow which feeds the discharge. The springs have close affinity with other hot spring systems on Coromandel and Great Barrier Island.
