摘要: 塔里木盆地西北缘阿克苏肖尔布拉克震旦系剖面发育一套基性火成岩,累计厚度超过 100 m,其岩相学特征和形成时代存在争议。综合野外考察、镜下特征和 K-Ar 法年龄测试,确定这是一套顺层侵入的浅成辉绿岩,其 K-Ar法测试年龄为 452.56×10 6 a±17.53×10 6 a,侵位时代相当于中-晚奥陶世。

Abstract: A suit of basic igneous rocks with accumulating thickness over 100 m developed in the Upper Sinian profile in Xiaoerbulake of Akesu, northwestern margin of Tarim basin. Nowadays, the lithofacies and forming age of them are still controversial. Based on field investigation, identification under microscope and K-Ar isotopic dating, it is confirmed they are a suit of diabases intruded along the bedding and have a K-Ar age of 452.56×10 6 a±17.53×10 6 a. The emplacement age corresponds to the Middle-Late Ordovician.

Key words: Akesu, igneous rock, Xiaoerbulake profile, K-Ar age dating
