摘要
The sequence stratigraphy of the Guantao Formation was investigated by integrating lithostratigraphic, well log, paleontological, and seismic stratigraphic data.Three system tracts, LST (low-stand system tract), TST (transgressive system tract) and HST (high-stand system tract) were recognized. Based on base-level cycle analysis, three kind of base-level cycles (SSC:short-term baselevel cycle sequence; MSC: medium-term baselevel cycle sequence; and LSC:long-term baselevel cycle sequence)in Guantao Formation were recognized.
