【摘要】 通过对峨眉山玄武岩含铜性及与铜矿的关系研究 ,提出玄武岩铜矿存在两个阶段成矿作用 ,即火山活动阶段和后期热液活动阶段成矿。控矿条件有 :( 1 )喷发中心地区火山沉积富铜矿源层 ;( 2 )具相当规模的水循环系统 ;( 3)与矿源层有较大接触面的容矿构造。更多还原

【Abstract】 On the basis of study on relationship between coppery how much of Emeishan Basalt and copper deposits,in the paper is made that formation of basaltic copper deposits exist in two stages,i.e. volcano activity stage and mineralization stage of thermal activity in the late. Controlled copper deposits are mineral forming copper source layer of volcano deposition in the volcano eruption crater,large-scale water circulatory system and ore-basaltic structure possessed big contact plane with copper source layer.更多还原
