| 摘 要： | 桂北银山岭花岗岩位于南岭钨锡多金属成矿带中段,距海洋山加里东期花岗岩体约2km,该岩体内部发育有构造蚀变岩型锡铅锌多金属矿床.本文应用高精度锆石SHRIMP U-Pb法,获得银山岭中细粒含斑黑云母二长花岗岩体形成年龄为426.3±4.2Ma (98％可信度,MSWD= 1.0),与其南部海洋山花岗岩岩基形成年龄基本一致...

| Abstract: | Yinshanling pluton is a small stock in the middle of Nanling metallogenic belt,internal of which exists a structural alteration-type Tin-polymetallic deposit.Zircon SHRIMP U-Pb dating of porphyrictic monzogranite therein shows Yinshanling stock formed at 426.3±4.2 Ma(MSWD=1.0),which similar to Haiyangshan batholith in the south,furtherly indicates they both were intruded in late Caledonian.Based on the geological investigate of Yinshanling deposit,the Yingshanling pluton is only the hostrock of this tin-polymetallic deposit,which was probably formed in Indonisian. |
