西藏邦铺斑岩型钼铜矿区地质及地球物理特征与扩大找矿前景分析

邦铺斑岩型铜钼矿床,成矿受二长花岗斑岩体控制。在矿区西南部,围岩蚀变标志明显指示为其矿化核心部位;矿体具有高电阻和中高强度的激发极化特性,并可以根据此特性指导找矿,综合物探资料表明该区与已知矿体部位类似。地质、地球物理特征指示出矿区西、西南部外围存在扩大找矿的良好前景。

Geological and geophysical characteristics and analysis on enlarging the prospect for prospecting work of Tibetan Bangpu porphyry-type molybdenum-copper mine area

The metallogenesis of Bangpu porphyry-type molybdenum-copper deposit is controlled by two long granite-porphyry bodies.In the southwest of the mine area,the markers of wall rock alteration obviously indicate the core positions of mineralization;the ore bodies have the characteristics of high resistance and high-to-middle induced polarization,and the prospecting work can be guided according to the characteristics.Comprehensive geophysical prospecting data show that this area is similar to the known ore body positions.The geological and geophysical characteristics indicate that there is good prospect for enlarging the prospecting work in the western and southwest peripheral space of the mine area.
