IDENTIFICATION OF SELF-POTENTIAL ANOMALIES OF DIFFUSION-ADSORPTION ORIGIN

Abstract

Diffusion and adsorption (DA) potentials are frequently the sources of self-potential anomalies, but they not arouse such practical interest as anomalies of red-ox and filtration origin. DA anomalies can be found everywhere and geophysicists sometimes make mistakes considering DA anomalies as examples of filtration anomalies. Identification of DA anomalies is based on correlation of SP and apparent resistivity values along the same profiles. At MSU students geophysical practice in Kaluga region we obtained profiles with SP and resistivity anomalies with good correlation between them. That fact allows consider such SP anomalies as a result of DA processes.
