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
