Identification of Self-Potential Anomalies of a Diffusion–Absorption Origin

Diffusion and adsorption (DA) potentials are frequently the sources of self-potential (SP) anomalies, but they do not arouse practical interest in contrast to anomalies of oxidation–reduction and filtration origins.

Summary:Diffusion and adsorption (DA) potentials are frequently the sources of self-potential (SP) anomalies, but they do not arouse practical interest in contrast to anomalies of oxidation–reduction and filtration origins. DA anomalies are common and geophysicists sometimes mistakenly consider 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. During the student geophysical training workshop for students of the Moscow State University (Aleksandrovka village, Kaluga Region) we obtained profiles with SP and resistivity anomalies with good correlation between them. This makes it possible to consider such SP anomalies as a result of DA processes.
