摘　　要：经研究作者认为，新疆兴地含铜镍基性超基性岩体是源自地幔的橄榄拉斑玄武质岩浆深部分异多次侵入形成的，成岩时代为中元古代，ｔ＝１２０９±３７Ｍａ；对形成铜镍硫化物矿床，具备有利的岩石构造环境组合、有利的成矿专属性和有利的成矿作用。The paper discusses the geological features and metallogenic conditions of the Cu-Nibearing basic-ultrabasic rock body in Xingdi, Xinjiang Autonomous Region. The main conclusions are as follows: (1) The rock body was formed by multiple intrusion of olivine tholeiite magma from the mantle. The diagenetic epoch was Mesoproterozoic, t= 1 209±37 Ma. (2) This intrusive had favourable assemblage of rock and tectonic setting, metallogenic specialization and ore-forming process for formation of Cu-Ni sulfide deposit.
