四川省凉山州拉拉铜矿落凼矿区深部矿床成因浅析

Genesis of Deep Deposits in Lala Copper Mine, Liangshan Prefecture, Sichuan Province

四川省拉拉铜矿落凼矿区位于凉山州会理县境内,是一个以铜为主,伴生钴、钼、铁、硫、金、银的重要金属矿床位于扬子准地台康滇地轴中段,扬子古板块川滇岛弧带的西南缘。早期形成的构造在震旦纪时期南北隆起对其进行继承并对其进行了改造,南北向构造带在此形成。区内具有非常突出的构造特征,呈现继承性及多期次的活动特征,该区具有非常突出的岩浆活动,不仅发育大量的超基性火山岩,同时还发育丰富的中性及酸性火山岩。区内矿床的形成与这些有利因素存在非常紧密的联系。文中主要对拉拉铜矿落凼矿区深部矿床成因进行探讨,旨在对区内的找矿工作提供一定的参考价值。

Located in Huili County, Liangshan Prefecture, Lala Copper Mine, Sichuan Province, is an important copper deposit associated with cobalt, molybdenum, iron, sulphur, gold and silver, located in the middle of Kangdian axis of Yangtze quasi-platform and the southwestern margin of Sichuan-Dian Island arc belt of Yangtze ancient plate. The area has very prominent tectonic characteristics, inheritance and multi-stage activity characteristics. The area has very prominent magmatic activity. It not only develops a large number of ultrabasic volcanic rocks, but also rich neutral and acidic volcanic rocks. The formation of deposits in this area is closely related to these favorable factors. This paper mainly discusses the genesis of deep deposits in Lala Copper Mine, in order to provide some reference value for prospecting work in this area.
