40Ar/39Ar Dating of Muscovite from the Zhelande Au Deposit, Irtysh Tectonic Zone, Xinjiang and Its Geological Implications

  • 哲兰德金矿是额尔齐斯构造带上重要的造山型金矿,产出于韧性剪切带中,金矿化赋存于黄铁矿化闪长岩脉、含金石英脉和黄铁矿化千枚岩中,矿化与韧脆性剪切变形有关。沿剪切面理发育的白云母、绿泥石等新生矿物,为测定金矿形成时代提供了依据。本研究利用白云母40Ar/39Ar年代学手段,确定了韧性剪切带的形成时代和金成矿时代。结果表明白云母坪年龄为295.4±1.6 Ma,韧性剪切变形和金成矿作用发生在295 Ma,略早于多拉纳萨依金矿形成时间。结合前人资料认为,新疆额尔齐斯构造带造山型金矿形成于295~270 Ma。
