摘要: 对塔里木盆地塔西南、巴楚、满西、和田河、塔中及塔北地区晚泥盆世晚期至早石炭世早期地层进行了层序地层分析,识别出两个层序(相当Vail 等提出的三级层序),认为这一时期塔里木盆地经历了两次较大规模的海平面升降运动。通过层序地层和生物地层研究认为,古塔里木海晚古生代发生的海侵起始于晚泥盆世法门晚期;“东河砂岩”的时代为晚泥盆世法门晚期。

Abstract: This paper makes sequence stratigraphy analysis of Upper Devonian-Lower Carboniferous in southwestern Tarim,Bachu, Manxi, Hotan river, Tazhong and Tabei areas, and two sequences (corresponding to three-order sequences presented by Vail) were identifed. It is considered that Tarim basin have undergone two lange scale sea-level fluctuation. On the basis of sequence stratigraphy and biostratigraphy analyses, it is suggested that Paleozoic transgression of Tarim basin began at the Late Famenian in Late Devonian, and the age of“ Donghe sandstone”should be at the Late Famenian in I ate Devonian.
