摘　　要：The Cretaceous is one of the important periods of global drastic changes in geological history, and the paleoclimate and paleoenvironment in the period are now frontier research fields in geoscience. The record of the Cretaceous marine facies has been taken as a focal dissected object by 'Global Sedimentary Geological Program (GSGP)'. But the terrestrial sedimentary rocks were mainly formed in China during the Cretaceous,
