Abstract:
Cuprita copper deposit is located at the middle of Andean metallogenic belt, where distribute many porphyry copper-gold deposits and epithermal gold-copper-lead-zinc deposits. Due to largely cut topography, high altitude and harsh natural environment, it is more difficult for prospecting and exploration. Based on tectonic lithofacies research and analysis, the remote sensing-tectonic lithofacies interpretation route observation, valley system secondary halo soil survey, geology mapping and tectonic lithofacies analysis were used for prospecting predictions in Cuprita copper deposit. The results are as follows. ① Comprehensive tectonic lithofacies analysis is a fast and efficient exploration methods for minerals exploration in Bolivian plateau special scenic area. ② Through remote sensing-tectonic lithofacies interpretation route observation, the volcanic dome faults and mineralized alteration are delineated, the mapping units and corresponding remote sensing abnormal color spot sign are established. ③ By geological mapping on a large scale ore-bearing strata, the ore-bearing lithofacies and ore-storing structural styles are determined, occurrence of mineralized alteration zone is showed in the anomaly area, the trend and tendency of mineralized alteration zone are revealed, which provides a design basis for probing trough and borehole verification. ④ Shallow ore bodies are exposed, geochemical anomalies are evaluated by probing trough, and the occurrence of ore body is further determined. Through borehole verification, it is controlled to thick and large copper ore bodies. ⑤ On the basis of tectonic lithofacies cataloging of probing trough and borehole cores, the analytical study of structural petrography is carried out, and it is predicted that there is a potential to search for porphyry copper deposits in the deep. Comprehensive tectonic lithofacies exploration method is fast and efficient in Bolivia plateau, meanwhile provides a reference example for exploration of the same type copper deposit abroad.
