People always tend to consider the metal ions adsorbed in geoelectric process as the formation mechanism of geoelectric chemistry (CHIM) anomaly. In this paper, contrast between major (Fe and Al) and trace elements' anomalies in several deposits was made. The result shows the high consistency between them. As we know, Fe, Al and other major elements are usually the main compositions of clay minerals. In addition, a large number of clay mineral particles whose sizes are from a few microns to tens of microns were found in the geoelectric foam plastic carrier through SEM observation. It can be accordingly inferred that the anomaly of CHIM is caused by fine-grained clay mineral particles that exist in soil, and these particles have electric activity and can be adsorbed selectively by CHIM process.
