摘　　要：从多旋回大地构造演化观点出发,分析了吉林省区域多旋回构造运动,控制多旋回的基性、超基性岩浆活动及其相应的成矿作用.与含镍有关的基性超基性岩体,主要受"台槽边界"赤峰-开源深断裂控制,沿深断裂一侧或其两侧成带分布、分群集中.含铜镍岩体类型有超基性岩型、基性-超基性岩型和基性岩型.成岩成矿是"多旋回、多期次、多阶段的产物";按成矿作用和成矿阶段可分为深熔贯入型、分层熔离型、残余熔浆型.On the basis of polycycle geotectonic evolution,the study is made about the regional polycycle tectonic movement in Jilin Province and the basic-ultrabasic magmatidc activities that control polycycle and their corresponding metallogenic processes.It is considered that the basic-ultrabasic rock bodies related with nickel are controlled mostly by Chifeng-Kaiyuan deep fault, which is a boundary between platform and the deep fault.It is proposed that the lithogenesis and metallogenesis result from polycycle,polyphase,polygenic and multistage.According to metallogenesis and metallogenic stages,they can be divided into anatexis injection type,layered differentiation by lipuation type,and remnant magmatic melt type.It is shown that the types of copper-nickel bearing rock bodies contain ultrabasic rock,basic-ultrabasic rock and basic rock.That basic characteristics and metallogenesis discussed provide some geological references for regional prospecting of copper-nickel deposits.
