SPONTANEOUS POLARIZATION STUDIES*

Abstract
Self potential measurements, both in drill holes and on surface, have been made in and around sulphide mineralization. Similar measurements were carried out on small scale laboratory models. The potential and current configurations around theoretical sulphide bodies are also described. Results of the model and field work seem to verify, in a qualitative manner, the electrochemical mechanism of spontaneous polarization proposed by Sato and Mooney. Possible causes are suggested for the abnormally large surface anomalies frequently found in the field.
