论文摘要
色尔腾山岩群是华北克拉通中西部早前寒武纪变质结晶基底的主要组成部分,对研究华北克拉通基底演化具有十分重要的意义。色尔腾山岩群的形成时代是目前研究的热点之一,本文通过岩石学和锆石SHRIMP U-Pb定年研究,查明了内蒙古乌拉特中旗乌兰乡查干哈达地区色尔腾山岩群东五分子岩组的岩石组成和年代学特征。东五分子岩组遭受了后期岩浆和构造作用的强烈破坏,未见顶底,主要由中细粒斜长角闪岩、细粒黑云斜长片麻岩、眼球状细粒黑云斜长片麻岩、条带状细粒黑云斜长片麻岩和细粒黑云角闪片岩组成,矿物组合特征指示岩石经历了低绿片岩相—低角闪岩相变质。其中,眼球状细粒黑云斜长片麻岩出露相对较厚,与细粒黑云斜长片麻岩多呈互层状产出,局部偶夹细粒黑云斜长片麻岩。本次研究选取其中新鲜的细粒黑云斜长片麻岩进行了锆石SHRIMP U-Pb测年分析,其锆石多呈自形—半自形,发育震荡环带,主体为岩浆成因,锆石SHRIMP U-Pb定年结果为（1 930.7±9.6）Ma,代表原岩（中酸性火山岩）冷凝结晶年龄,表明东五分子岩组经历变质作用的时代应晚于1 930Ma。
