Exploration Activity: Groundwater Sampling At Kilauea East Rift Geothermal Area (Cox & Thomas, 1979)

Exploration Activity Details
Location	Kilauea East Rift Geothermal Area
Exploration Technique	Groundwater Sampling
Activity Date	1973 - 1977
Usefulness	useful regional reconnaissance
DOE-funding	Unknown

Exploration Basis

This study was conducted as part of the Hawaii Geothermal Project in order to gain an understanding of the geothermal potential in Hawaii.

Notes

Cl/Mg ratios and SiO2 concentrations have been analyzed in the ground water around Hawaii as and indicator for geothermal resources. This method has been conducted in order to locate areas which might warrant further geothermal investigation. SiO2 and Cl/Mg measurements of nearly 400 groundwater sample were done. it was found that measuring Cl/Mg ratios in groundwater can be a useful geochemical indicator for geothermal exploration when other water chemistry techniques are ambiguous. This research was useful for locating some areas which would be good for further investigation
