江西大吉山钨矿容矿裂隙演化及与成矿关系探讨

摘要

Dajishan tungsten mine is China's largest tungsten quartz vein -type deposits of wolframite. Four geological fractures, east-west, north-east, north-north-east and north-west-west, Mine development stuff, North East, North, North East, North West four fracture, are the major features of its mining development. The NE-trending fault is the main ore-controlling and rock-controlling structure. The NE fault and NWW ore fissures compose the staircase -like structural framework. The NWW ore fissures are resulted from Evolution of regional tectonic stress field and magma intrusion backwater coupling.%大吉山钨矿是我国规模最大的石英脉型黑钨矿床之一.矿区发育东西、北东、北北东、北西西四组断裂,北东向断裂为矿区主要控岩控矿构造,北东向主干断裂与北西西容矿裂隙构成矿区楼梯状构造格架.北西西向容矿裂隙是区域构造应力场演化与燕山期岩浆上侵顶托耦合的结果.
