| 摘 要： | 塔里木克拉通的研究可以有助于理解中亚造山带元古代构造框架和Rodinia 超大陆的形成过程。位于塔里木克拉通北缘的库鲁克塔格地区广泛分布有基性岩-超基性岩-碳酸岩，并且伴随有铜镍、铁磷和蛭石矿床，其典型矿床为兴地铜镍矿床、且干布拉克蛭石矿床、大西沟和卡乌留克铁磷矿床。SIMS 锆石U-Pb 年代学研究表明，大西沟铁磷矿床形成于古元古代(2 452±10 Ma)，其它铜镍、铁磷和蛭石矿床(兴地、卡乌留克和且干布拉克)形成于新元古代(812～707 Ma)。古元古代成矿作用与哥伦比亚超大陆的汇聚碰撞有关，而新元古代成矿作用形成于Rodinia超大陆裂解导致塔里木地幔柱活动有关的成矿动力学背景。

| Abstract: | The Tarim Craton is an important tectonic unit and a suitable target to investigate and understand the Proterozoic tectonic framework of the Central Asian orogenic belt and are widely distributed in the Quruqtagh domain of NE-tarim. In Quruqtagh, Cu-Ni, Fe-P and apatite-vermiculite deposits hosted in the mafic-ultramafic-carbonatite rocks occur in the Xingdi, Qieganbulake, Daxigou and Kawuliuke. These deposits related to the mafic-ultramafic-carbonatite rocks in Quruqtagh formed in the period between Paleoproterozoic and Neoproterozoic. The Paleoproterozoic Fe-P deposit is represented by the Daxigou deposit that yielded a SIMS U-Pb zircon age of 2 452± 10 Ma. The other Cu-Ni, Fe-P and apatite-vermiculite deposits hosted in the mafic-ultramafic rocks formed in the Neoproterozoic, represented by the Xingdi, Kawuliuke and Qieganbulake deposits that formed between 812 Ma and 707 Ma. The Paleoproterozoic mineralization event was coincident with the global collisional events that led to the assembly of the Paleo-Mesoproterozoic Columbia （Nuna） supercontinent. And the emplacement of these Neoproterozoic mafic-ultramafic-carbonatite rocks was related to a mantle plume event that led to the breakup of the Tarim Craton from the Rodinia supercontinent. |
