Abstract云南临沧锗矿床产在以临沧花岗岩为基底的中新世断陷盆地中。已有研究表明,成矿元素Ge来自基底花岗岩,但临沧花岗岩是复式岩基,具有多期次的岩浆活动,而Ge来自哪期岩浆活动并不清楚。文章对采自晓街、临沧、勐库和勐海的7个花岗岩样品(纵贯临沧岩基)进行了LA-ICP-MS锆石原位Ge元素含量分析和U-Pb年代学研究。研究结果表明,岩基主体岩浆活动时代与前人研究成果一致,为(215.6±2.7)Ma~(236.9±3.7)Ma,同时也有少量继承锆石(303~2533 Ma);w(Ge)在主岩浆期的锆石中为0.23×10-6~4.21×10-6,平均0.53×10-6,在继承锆石中为0.34×10-6~3...
