In this paper, the authors carried out tentative research and promotion application, which constitute an integrated approach to valley system secondary halo-remote sensing-tectonic lithofacies interpretation in basin-orogen-plateau inlaid structure and special landscape zone of the Tupiza and Cuprita copper deposits, Bolivia. Key points of combinational method and application effect are as follows: ① The key is interpreting mapping unit by remote sensing-tectonic lithofacies, which serves as base map of valley systems secondary halo and tectonic lithofacies mapping unit. Remote sensing-tectonic lithofacies interpreting can identify topography and landscape cell rapidly, and improve effective point ratio of geologic mapping and sampling of valley systems secondary halo. ② Sampling horizon and sampling depth were determined tentatively. It is known that the main sampling horizon is B soil and the best sampling size fraction is -10~+60 mesh grain size. ③ The technical method has achieved good results in application and promotion in the Tupiza and Cuprita copper deposits, which proves that the combination of technical methods is an economic, efficient and rapid comprehensive evaluation technique in basin-orogen-plateau inlaid structure and special landscape area of Andes. It also provides an effective exploration route of overseas investment, so as to control risk for Chinese-funded enterprises.
