| Abstract: | Based on such characteristics of the contact metasomatic skam copper deposit as strata, intrusive bodies, ore-control structure, alteration zones and mineral geology and geochemistry, in combination with element associations, primary anomalies and zoning regularity of element anomalies, the authors have summed up three kinds of geochemical exploration criteria for the skarn deposit, i. e. , rock body evaluation, erudition degree and concealed ore prognosis, which provide scientific basis for the exploration of this kind of ore deposits. |
