Based on a study of the relationships between anomalies of regional geochemical deep layer samples, geophysical gravity and magnetic anomalies and remote sensing interpretation, the authors hold that the anomalies of elements in deep layer samples are composed of four parts, i.e., indicator elements for concealed structures Au and Hg, elements of acid rocks related to gravity negative anomalies Sn, Be, F and Y, elements of basic rocks related to aeromagnetic positive anomalies Fe, Co, Ni, V, Cr and elements related to strata Cd, T and Tl. This study has explained the causes of element anomalies from deep layer samples and opened up a new way which combines regional geochemical and geophysical exploration with remote sensing interpretation.
