摘要
中国铜镍硫化物矿床控制的关键因素是岩浆岩岩石组合和构造环境，并以此作为划分矿床类型的依据。划分为过渡带内、地槽区内和与火山活动有关的侵入体类矿床三大类和１６种岩石组合类型。并从大地构造环境、深（大）断裂、成岩时代、复式岩体、岩石组合、岩体规模产状、岩石化学、稀土元素、岩体分异程度、造岩矿物和岩石蚀变等１０个方面，论述对铜镍硫化物矿床的控制作用。
Key factors to control the mineralization of Cu-Ni sulfide deposits in China are the magmatic rock association and tectonic setting which are the evidences to classify the Cu-Ni sulfide deposits in China into three types,i.e. type in transitional zone,in geosyncline and that in intrusions related to volconism,and sixteen rock association types.Ore-controling factors of the deposits are also discussed from tectonic setting,deep fault,oreforming age,complex intrusion,rock association,intrusion scale and occurrence,petrochemistry,rare earth element,differenciation degree of intrusive rocks,rock-forming mineral and rock alteration etc.
