| 摘 要： | 笔者将兴地基性超基性杂岩划分为南北两个岩带．南岩带（称为兴地河基性超基性岩带）形成于中元古代，系幔深橄榄拉斑玄武质岩浆活动的产物，具铜镍硫化物成矿专属性，北岩带（称为且干布拉克-团结村偏碱性超基性岩带）形成于晚元古代，系幔源碱性橄榄玄武岩浆、碳酸岩浆及类金伯利岩浆活动的产物，具蛭石、磷灰石、透辉石成矿专属性。

| Abstract: | Xingdi basic-ultrabasic complex bodies are divided into two rock belts.The south belt is attributable to products of the mantle-derived olivine tholeiitic magmation of Middle Proterozoic Subera, and has the metallogenetic specialization of copper-nickel sulfide.The north belt is attributable to products of the mantle-derived alkali olivine basalt, carbonatite and kimberlite-like magmation of Upper Proterozoic Subera, and has the metallogenetic specialization of vermiculite-apatite-diopside. |
