Detailed geologic mapping and bore data were taken to reveal the Quaternary tectonic, sedimentary and geomorphic characteristics and tectonic-sedimentary evolution of Lujiao area, northeast Yuanjiang sag. The study area rose as a whole and was denuded during late Middle Pleistocene. The western main depressional area was stable or subsided weakly and formed clay deposits in Late Pleistocene, when east area rose by fits. In the same time of above tectonic uplift since late Middle Pleilanguage: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA" lang=EN-US>stocene, east of the area tilted westward and northward. The area was under tectonic stable state in Holocene, forming alluvial-lacustrine deposits in western Dongting Lake area.
