Abstract:

铜山口铜-钼矿床发育有夕卡岩型和斑岩型两类矿化,是鄂东南矿集区内典型的夕卡岩-斑岩复合型矿床。成矿作用与铜山口花岗闪长斑岩岩株和大冶群碳酸盐岩有关,矿体主要沿两者的接触带分布。本文利用激光阶段加热技术分别对两类矿化有关的蚀变矿物金云母和绢云母进行40Ar/39Ar年龄测定。结果表明,铜山口矿区经历了两次蚀变一矿化事件:铜山口矿床成矿作用发生于约143±0.3Ma,而矿区东南缘的牛鼻峰石英二长斑岩的热液蚀变发生于约129Ma。牛鼻峰石英二长斑岩的侵位及蚀变对铜山口矿床斑岩型矿化的部分地段产生热扰动,导致绢云母40Ar/39Ar年龄比实际矿化蚀变年龄偏年轻。铜山口矿区两次蚀变-矿化年龄分别与长江中下游成矿带早晚两期成岩成矿事件(145-133Ma和130-120Ma)一致。岩石圈伸展及幔源玄武质岩浆底侵作用可能是区域上大规模岩浆活动与成矿作用的深部地球动力学因素。
