中文摘要:
      新疆阿勒泰南缘赛都金矿是典型的大型韧性剪切带型金矿。采用原位激光剥蚀同位素质谱(LA-ICP-MS)对赛多金矿含金石英脉中锆石定年,获得含金石英脉的形成年龄为303±3 Ma,结合前人报道相关年代学资料,表明赛都金矿经历了三期主要构造—热液活动—成矿作用,发生的时间分别是310 Ma、290 Ma和270 Ma左右。这一研究结果不仅准确地确定了赛都金矿的成矿时代和成矿阶段,而且对阿勒泰南缘额尔其斯构造带的演化提供了重要的新资料。
英文摘要:
      The Saidu gold deposit in southern Altaid is a typical ductile shearing type gold deposit of large size. In this contribution, we reported zircon LA-ICP-MS U-Pb age of the gold-bearing quartz veins from this deposit, in combination with previously reported geochronological data, we suggest that there existed three main structure-hot water-mineralization stages of this deposit, i.e., ca.310 Ma, ca.290 Ma and ca.270 Ma. This study not only clearly determined the mineralization age and stages, but also supply new data for deciphering the tectonic evolution of the Erqisi suture zone in southern Altaid.
