新疆准噶尔晚古生代陆壳垂向生长(Ⅰ)——后碰撞深成岩浆活动的时限

  • 基金项目:

    国家重大基础研究规划项目(2001CB409802)资助成果.致谢 承蒙张立飞提供庙儿沟紫苏花岗岩的SHRIMP锆石U-Pb定年结果;参加部分野外和室内工作的还有李辛子、李宗怀等;年龄测试过程中还得到北京离子探针中心刘敦一等的支持和帮助,在此表示衷心感谢.本文工作还部分地得到了教育部“跨世纪人才培养计划”的资助.

  • 准噶尔是新疆北部古生代造山带的重要组成部分,以广泛发育晚古生代后碰撞花岗岩为特征,是中亚造山带中显生宙陆壳生长作用非常显著的地区之一。根据新近获得的SHRIMP锆石U-Pb年龄,并参考已经发表的锆石U-Pb年龄,本文重新厘定了准噶尔晚古生代后碰撞深成岩浆活动的时限。按照最新的国际地质年表中石炭纪和二叠纪划分方案(Gradstein et a1.,2004),准噶尔后碰撞深成岩浆活动是从早石炭世中-晚维宪期开始、于早二叠世末期结束的。东准噶尔后碰撞深成岩浆活动发生在330-265Ma之间,而西准噶尔后碰撞深成岩浆活动的时限在340-275Ma之间,持续时间分别约65Ma。但是,在东准噶尔,后碰撞深成岩浆活动集中在330~310Ma和305~280Ma两个时段发生,而在西准噶尔,后碰撞深成岩浆活动的高峰发生在310~295Ma之间。准噶尔晚古生代后碰撞深成岩浆活动在空间上没有受到重要地质界线(如蛇绿岩带)的分隔控制,在有的地方花岗岩还可以侵位在蛇绿岩带之中。而晚古生代后碰撞深成岩浆活动不但在准噶尔分布广泛,而且在准噶尔北邻的阿尔泰造山带和南邻的天山造山带中均有出现,具有广泛的区域性。
