摘要: 对塔里木盆地塔中地区M-1井的石炭系大孢子进行了研究,建立了盆地晚石炭世维斯发期大孢子组合,并与河北开平盆地上石炭统本溪组和太原组、内蒙古的太原组、甘肃靖远地区靖远组、宁夏石咀山地区羊虎沟组以及法国萨尔-罗林地区等国内外相当层位的大孢子组合进行了对比,确定化石所在层位的地质时代为晚石炭世维斯发期。首次报道塔中地区晚石炭世大孢子组合,对明确塔中地区卡拉沙依组“砂泥岩段”的时代及全盆地开展生物地层工作以及油气勘探研究具有深远的意义。

Abstract: Through a study of Late Carboniferous megaspores from Well M-1 in Tazhong area of Tarim basin, the megaspore assemblage of Westphalian stage of Late Carboniferous megaspore assemblage is established and the comparison of this megaspore assemblage is made with those in corresponding horizons at home and abroad such as Benxi and Taiyuan formations in Hebei province, Jingyuan formation in Gansu, Yanghugou formation in Ningxia as well as Sharl-Luolin area in France. The geologic age of the horizon where the assemblage lies is determined to be Westphalian stage of Late Carboniferous.This paper first reports the late Carboniferous megaspore assemblage in Tazhong area, which is of great significance for the biostratigraphic studies and the petroleum exploration and research in Tarim basin.

Key words: Tarim basin, Late Carboniferous, megaspore, correlation, comparison
