| 摘 要： | 本文从构造地球化学角度 ,论述了区内Ag、Pb、Zn等多金属成矿元素的聚矿成矿环境 ,阐述了成矿元素聚矿成矿与印支燕山期NNW向构造岩浆活动晚期脆性形变的密切关系。聚矿成矿具一定规律 ,受NNW向压性形变控制。从元素集散规律分析了区内的重要找矿前景 ,被破坏的NNW向构造岩浆岩带是该区寻找隐伏和半隐伏矿带的主要方向

| Abstract: | On the basis of tectono-geochemistry of the Wahongshan tectono-magmatic belt, the paper gives a detailed study of the ore-forming environment of Ag,Pb and Zn in the area studied. The result shows that the enrichment of ore-forming elements and the formation of orebodies have much relationship to late brittle deformation in the NWW-trending tectono-magnetic belt of Indosinian age. The formation of orebodies is controlled by the NNW-trending thrust faults along the belt. The position where the NWW-trending tectono-magnetic belt was destroyed by late brittle fault zones is the favorable locus for explorating blind ores. |
