江西东乡铜矿成矿地质特征与找矿实践
|
摘要
充分利用前人的研究成果,结合在赣东北地区的找矿实践,对东乡铜矿成矿条件、成矿特征等进行剖析,认为该矿为斑岩型铜矿,是赣东北斑岩铜矿带的一部分;矿区广泛分布的花岗闪长斑岩小岩体与深部隐伏斑岩体断续连接,是成矿物质和热能的主要来源。在此基础上开展了浅层地震找矿应用研究,为资源危机型矿山的地勘工作提供了一条新的思路和方法。
Based on the research findings of pre decessors and combining the practic e of prospecting in NE Jiangxi Province,we discuss the condition a nd the feature of metallogenic geolo gy,and think Dongxiang deposit is a porphyry copper deposit and it is a part of the NE Jiangxi porphyry copper metallogenic belt.Those small granodiorite-porphyry intrusive b odies connect with the deep conceale d granite-porphyry bodies,which are the main source of metallogenic material and energy.According to these studies we carry out geologic prospecting with the shallow seismic exploration.This method also offers a new way to solve th e crises of resource in congeneric mi nes.
