摘要： 本文系统地描述了新疆塔里木盆地轮南1井的中生代地层和古生物化石组合,将该井中生界自上而下划分为:卡普沙良群(K1kp)、 齐古组(J3q)、恰克马克组(J2q2)、克孜勒努尔组(J2k)、阳霞组(J1y)和阿合组(J1a)。作者根据岩石和矿物特征与库车洼地对比和植物化石将轮南1井4825～5039m井段划归侏罗统阿合组(J1a),并对该井段孢粉化石的时代进行了讨论。

Abstract: In this paper, the stratum and fossil assemblages of the well Lunnan—1 in Tarim Basin, Xinjiang, are systematically described . The Mesozoic stratum in this well has been divided in descending order as following： The Kapushaliang Group (K1kp)， the Qigu Fm, (J3q)， the Qiakemake Fm.(J2q2) ， the Kezilenur Fm. (J2k)， the Yang xia Fm. (J1y) and Arhe Fm. (J1a). Based on the correlation of lithological and mineral features between this well and the Kuche depression and plant fossils, the depth from 4825m to 5039m in this well us identified as the Lower Jurassic Arhe Fm., and also a brief discussion on the age of the fossil sporo- pollen assemblages found from this well depth is given.
