Comparison of anomalous effects determined using telluric fields and time domain I.P. technique (test results)

Abstract

Some characteristics of telluric activity at different frequencies were found to be anomalous over a mineralised quartz vein, also exhibiting a self-potential (S.P.) anomaly. Subsequently equipment capable of measuring the telluric field at 9.5 Hz and 22.5 Hz was developed and tested, together with time domain I.P. over a mineralised zone in Madhya Pradesh, India. The results of the telluric field data agreed qualitatively with time domain I.P. data. The results suggest a basis for a natural-field approach to I.P. techniques.
