| 摘 要： | 西藏玉龙斑岩铜矿是世界级超大型铜矿,从其发现开始迄今,众多学者对其展开了深入研究,积累了大量的资料.随着玉龙铜矿开发进入全面实质性阶段,迫切地需要对玉龙铜矿的研究成果进行系统的归纳总结,分析成矿地质特征以及成矿模式,以便指明玉龙铜矿的找矿方向,达到增加储量满足后续开发的需求.笔者利用Micromine软件建立了主要矿体的三维立体模型,分析了矿体以及矿石类型三维空间分布规律.通过总结常量元素、微量元素、稀土元素以及流体包裹体地球化学特征,分析同位素测年,厘定矿床成矿时代,建立出玉龙斑岩铜矿成矿模式.该模式的建立对于玉龙斑岩铜矿乃至三江地区斑岩铜矿床找矿突破和潜力评价具有重要的指导意义和应用价值.

| Abstract: | The Yulong porphyry copper deposit, one of the super-large porphyry copper deposits in the world, has aroused great interest among researchers and a great amount of achievement has been made since its discovery. With the exploitation of Yulong porphyry copper deposit entering into a new phase, it is important to review and summarize the study results of Yulong porphyry copper deposit because the understanding of mineralization characteristics and model will not only give a exploration direction in the area but provide a solid base for subsequent exploration. This study, taking use of Micromine, established a 3-D model of main orebodies and then analyzed the spatial distribution rules of orebodies and ore types. Based on the analysis of whole-rock, trace elements and REE, and geochemical characteristics of fluid inclusion, metallogenic model of the Yulong porphyry copper deposit in combination with isotopic dating was established. Therefore, the establishing of the model is of great significance for guiding the exploration breakthrough and potential assessments both in the Yulong porphyry copper deposit as well as porphyry copper deposits in the Sanjiang area. |
