Remote Sensing Interpretation of Geological Structure Features Based on WorldView2 Data of Pulang Cu Deposit,Yunnan Province
The Pulang copper deposit in Yunnan is a super-large porphyry-type deposit located at the southern end of the Yidun Island arc.The geological structure of this area is complex,with limited research on the continu-ity of the structural features between the mining area and the surrounding areas,as well as the secondary struc-tures within the mining area.This study employs remote sensing geological interpretation at different scales to in-vestigate the Pulang mining area.On remote sensing images,the Pulang-Songnuo region exhibits a large circular structure,identified as a geological anomaly unit within the "Southwest Sanjiang Metallogenic Belt."The distribu-tion of porphyries within this unit reveals the overall spatial extent of the dome structures formed by the intrusion of porphyritic rocks.High spatial resolution WorldView2 images reveal secondary circular and linear structures of varying scales within the Pulang mining area.Based on the analysis of circular structures related to intrusive rocks,alteration of surrounding rocks,and mineralization,this paper proposes remote sensing exploration indica-tors for the Pulang mining area,outlining prospective exploration areas.
