江西崇义牛角窝钨多金属“三位一体”矿床类型及成矿机制探讨

摘要

崇义牛角窝钨多金属矿床位于南岭东部钨锡多金属成矿带崇义-大余-上犹矿集区内。矿区产出破碎蚀变岩-石英脉复合型、石英细脉带型、云英岩型三种钨矿床类型，同受燕山期成矿花岗岩体控制，且三种矿床类型具有一定的空间配置关系，相互间具有密切的成生联系，从而形成“三位一体”模式。对矿区“三位一体”模式的研究有助于深刻认识钨多金属矿床的组合产出规律，进行钨矿床地质特征及成矿机制探讨，指导矿区勘查和区域找矿。%Niujiaowo tungsten polymetallic deposit is located in the Chong-Yu-You ore concentration area of eastern Nanling tungsten-tin polymetallic metallogenic belt. The tungsten polymetallic district occurs in three deposit types including fractured altered rock-quartz vein type, quartz veinlets zone type and greisen type. These types are demonstrated in the form of"three-in-one", are all controlled by the Yanshan metallogenic granite bodies. This paper studies the geological characteristics and metallogenic mechanism by conducting comprehensive analysis of the deposit.
