The characteristics of elements content can be somewhat reflected by remote sensing. The remote sensing geochemistry can provide a parameter in many areas, especially in low geological exploration regions or in areas abroad where the acquisition of geological data are difficult. In this paper, according to the relationship between the element content and the spectra, four indicators of the remote sensing geochemical model were established, i.e., correlation slope of bands, slope index of bands, absorption depth of index of bands, and polynomial related index of bands. With the Duolong ore concentration area in Tibet as the study area, Cu element remote sensing geochemistry based on regression algorithm is in accordance with the measured Cu geochemistry, and F test confirmed the credibility of the inversion results. The remote sensing Cu geochemical results are good and can be considered to be an independent remote sensing parameter, as demonstrated by the comparison between the measured Cu element geochemistry and the remote sensing alteration anomalies.
