Abstract

Abstract: The sedimentary rocks formed in Pukou stage of Late Cretaceous period are distributed widely in the Lower Yangtze area. There occur different rock assembles. Remnant rocks in the southern zone are thin and fine, while in the northern zone thick and coarse. The sedimentary facies includes alluvial fan, fan-delta, offshore lake, shallow lake and deep lake facies. The sedimentary basin was rebuilt by the Nanxiang movement and stage Ⅰ,Ⅳ,Ⅴ of Yanshan movement. The evolution of palaeogeography in this region took place under the background of subduction of the Kula-Pacific plate in NNW direction.

Key words: Lower Yangtze area, Pukou stage, sedimentary palaeogeography
