朱布镁铁-超镁铁侵入岩赋存有中型硫化物铂族元素矿床。根据岩体大小和矿床储量的简单质量平衡计算，矿床的形成需要至少3000倍现存岩体体积的岩浆参与成矿，因此朱布岩体应该是峨眉山玄武岩的输送通道。岩体的年龄、地质特征、地球化学都支持这个结论。岩体的原始岩浆应该属于峨眉山高钛玄武岩。 |

The Zhubu mafic-ultramafic intrusion is a medium-sized deposit of Pt,Pd,Cu and Ni.The simple mass balance calculation based on the size and reserves of the deposit showed that the volume of magma involved in the mineralization should be,at least,3000 times that of the intrusion.So the intrusion can be considered as a fossil conduit of the Emeishan basalts.The viewpoint is consistent with the geology,age and geochemistry data of the Zhubu intrusion.The parent magma of the Zhubu intrusion should belong to the Emeishan high-Ti basalt. |
