EMPLACEMENT AND DEFORMATION AGE OF SURROUNDING GNEISSIC GRANITE IN WULONG GOLD DEPOSIT, EASTERN LIAONING PROVINCE: SHRIMP U-PB AGE

  • 摘要: 为了确定五龙金矿围岩的侵位和变形时代,进一步探讨辽东地区晚中生代构造体制转折时限,采用岩相学观察和锆石SHRIMP U-Pb定年技术,对辽东五龙大型金矿的围岩五龙岩体、侵入五龙岩体中的花岗斑岩脉和三股流岩体进行了研究。结果表明,五龙岩体具弱片麻状、片麻状构造,花岗斑岩脉也发生了变形作用,三股流岩体未发生变形作用。五龙岩体SHRIMP U-Pb年龄为(159.2±1.9)Ma和(160.0±1.4)Ma,花岗斑岩SHRIMP U-Pb年龄为(132.14±0.85)Ma,三股流岩体SHRIMP U-Pb年龄为122~124 Ma。辽东五龙岩体经历的推覆、挤压事件止于132~124 Ma。辽东地区晚侏罗世的推覆、挤压事件与古太平洋板块向欧亚大陆俯冲作用关系密切,五龙金矿的成矿大地构造背景亦与此次俯冲有关。
