Exploration Basis

Identify the source of chlorine

 

Notes

The ³⁶Cl/Cl values for several geothermal water samples and reservoir host rock samples have been measured. The results suggest that the thermal waters could be connate waters derived from sedimentary formations, presumably underlying and adjacent top the granitic rocks, which have recently migrated into the host rocks. Alternatively, most of the chlorine but not the water, may have recently input into the system from magmatic sources.
