Abstract:

雅鲁藏布江结合带在东构造结地区形成弧形展布的蛇绿混杂带,此前对该带蛇绿岩的地球化学特征和成因已有研究,但年代学研究十分薄弱。本文报道对该带蛇绿岩的地质年代学研究成果。从变玄武岩和变辉长岩中分选出两类锆石。一类锆石为自形的柱状双锥,具有清晰的同心韵律环带,较高的Th/U比值(主要为0.63-2.79),SHRIMPII测出的年龄为185.8±1.7Ma(MSWD=0.64,n=11)。另有3颗此类锆石经SHRIMPII和LA-ICP-MS分别测出207±29Ma(MSWD=6.5)、209±20Ma(MSWD=3.0)年龄值。另一类锆石为它形、半自形长柱-短柱状双锥,内部呈扇状分带、弱分带或无分带,具有较低Th/U比值(主要为0.005-0.033),经SHRIMPII测出32.74±0.65Ma(MSWD=0.92,n=11)年龄值。还有一些变质锆石测出82.8-70.8Ma等年龄。测年结果表明蛇绿岩形成时代为早侏罗世,局部可能为晚三叠世。笔者认为新特提斯洋在晚三叠世至早侏罗世发生向北的俯冲消减,在晚白垩世闭合,蛇绿岩构造侵位。
