摘　　要：古老的变钠质中基性火山杂岩———细碧-角斑岩是龙脖河矿区东带铜矿床的成矿基础,在经历了长期的构造变质变形作用后,它形成了两类最具工业开采价值的铜矿床,矿床的形成与火山喷发活动和后期构造作用关系密切,成矿作用多期次特征明显。Ancient sodium intermediate - basic volcanic complex （ spilite - keratophre） is the ore - forming foundation in the eastern Longhohe copper belt. After long - term metamorphic tectonics and post - metamorphic deformation, two type copper deposits with industrial value are formed. Formation of the deposits has fight relations with volcanic eruption and late tectono - metamorphism. Multi - stage mineralization is obvious.
