Research Status of the Quaternary Sedimentation in the Chengdu Basin

The Quaternary of the Chengdu Basin contains abundant geological information. After being studied for decades, there are still some disputes over the Quaternary sedimentary environment and evolution and the filling sequence of basin, etc., on the whole even though some common perspectives have been reached with regard to stratigraphic architecture and structural characteristics. Particularly, more aspects must be further studied, including gravel characteristics and response to tectonic activity.
