滇西北香格里拉红牛铜矿床地球物理特征及找矿预测
Geophysical characteristics and prospecting prediction of Hongniu copper de-posit in Shangri-La,northwestern Yunnan
摘要
Abstract
The Hongniu copper deposit is located in the Zhongdian arc at the southern segment of the Yidun arc,be-longing to the Dege-Xiangcheng Cu-Pb-Zn-Ag polymetallic metallogenic belt,and possesses significant prospec-ting potential.Through a study of the anomaly characteristics and exploration applications of high-precision mag-netic surveys and time-frequency electromagnetic(TFEM)methods,this paper reveals that the"horseshoe-shaped"magnetic anomaly and the"island-like"low-resistivity and high-polarization anomaly correspond well to the ore(mineralized)bodies within the mining area,whereas the deep high-resistivity anomaly in the northern part coincides with the ore-forming quartz monzonite porphyry.The anomaly features derived from high-preci-sion reduced-to-pole(RTP)magnetic data and TFEM surveys provide effective exploration guidance for the ore-forming magmatic rocks,host rocks,and ore(mineralized)bodies in the mining area.On this basis,three con-cealed-ore exploration targets are delineated:the low-resistivity and high-polarization anomaly zone along the eastern contact belt of deep magmatic rocks,the low-resistivity and high-polarization anomaly zone at No.18 ex-ploration line in the southern part,and the weak RTP magnetic anomaly zone No.37 on the western side of the mining area,providing new insights and directions for further exploration in the mining area.关键词
