SEQUENCE STRATIGRAPHY IN DEVONIAN - CARBONIFEROUS TRANSIT PERIOD IN TARIM BASIN

Abstract

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.

Key words: Tarim basin, Sequence stratigraphy, Late Devonian, Early Carboniferous, Late Paleozoic, Transgression
