Abstract:

?大青山是华北克拉通西部孔兹岩带的典型地区之一.原划分的上乌拉山亚群孔兹岩系中存在古元古代早期和晚期的变质碎屑沉积岩.本文对它们进行了广泛的锆石SHRIMPU-Pb定年研究.6个变质碎屑沉积岩的碎屑锆石和变质锆石年龄变化范围分别为2.0~2.56和1.83~1.96Ga.结合已有研究,可得出如下结论:1)古元古代晚期孔兹岩系在大青山地区的空间分布上占有绝对优势;2)碎屑沉积岩物源区时代主要为2.4~2.5Ga和2.0~2.1Ga,分别与华北克拉通新太古代晚期到古元古代早期和古元古代中-晚期构造热事件相对应;3)大青山地区在古元古代晚期经历了长期复杂的演化过程,伸展抬升时间长达100Ma以上.
