| 摘 要： | 新疆坡北辉长岩体位于塔里木古陆东北缘的北山裂谷带中,坡一和坡十铜镍硫化物含矿超镁铁岩体位于坡北岩体内.尽管坡十超镁铁岩体与坡北辉长岩呈侵入接触,但两者的微量元素和同位素组成显示良好 的一致性,表明两岩相虽然分不同阶段侵入就位,但仍为同源岩浆的产物.MnO-TiO2-R2O5及Th-Hf-Ta判别图解显示坡北及坡十岩体的... |

| Abstract: | The Pobei gabbroic intrusion is located in the Beishan rift zone of the northeastern margin of Tarim craton.The Poyi and Poshi Ni-Cu bearing ultramafic bodies are situated in the western portion of the Pobei intrusion.It is sharp contact between the Poshi ultramafic body and the Pobei gabbro.However,both the Poshi ultramafic rocks and the Pobei gabbros have similar trace element and isotope compositions,indicating that they are comagmatic.The triangle plots of MnO-TiO2-P2O5 and Th-Hf-Ta show that the parent... |
| Keywords: | the Beishan rift zone the Poshi intrusion the Tarim large igneous province a metasomatized mantle |
