西藏雄村矿集区普钦木—哑达地区地球物理特征及找矿方向
Geophysical Characteristics and Prospecting Direction of Puqinmu-Yada Area in the Xiongcun District,Tibet
摘要
Abstract
Xiongcun district is located on the southern margin of the central segment of the Gangdese metallogenic belt.Extensive research and exploration have been conducted in this area.Through geophysical and geochemical exploration combined with engineering validation,Xiongcun No.1 and No.2 porphyry Cu-Au deposits were beendiscovered.Total Cu content exceeds 2.5 million tons,with associated Au over 250 tons and Ag over 1 000 tons,making it an exceptionally large-scale deposit.However,mumerous soil and Cu-Au rock element anomalies still exist in the periphery of No.1 and No.2 deposits in the Xiongcun district,requiring further evaluation to guide the deployment of exploration work.In this study,by summarising the geochemical anomalies of soil and rock in the Xiongcun district,we carried out an electro-excitation physical survey in the Puqinmu-Yada area,circled the J1 anomalous area with high apparent polarisation and low apparent resistivity in Puqinmu,and circled the J2 anomalous area with medium-high apparent polarisation and medium-low apparent resistivity in Yada.These two anomalies were also verified by drilling and trenching engineering,revealing Cu-Au ore bodies at the depth of the J1 and the surface of the J2 anomalies.It was discovered that these two anomalies were mineralized.It is proposed that the deep and marginal parts of the J1 anomaly and the deep parts of the J2 anomaly have significant potential for ore exploration,and are key areas for future ore exploration in the Xiongcun district.关键词
