 It is well known that the identification of sequence boundaries is the key to sequence stratigraphic research. Using the Xujiahe Formation in the Baojie Area of Sichuan Basin as an example, the authors recognized four types of sequence boundary on the basis of outcrop, drillcore, logging, and seismic. These different types of sequence boundary are represented by erosion surfaces, sedimentary facies changes, weathering crusts and sedimentary structure changes. Their characteristics, drill cores, outcrops, logging curves, and seismic sections are described in detail in this paper.
