摘要
The maximum flooding event and condensed section are one hot subject in modern se-quence stratigraphy and cyclic stratigraphy. Condensed section (CS)is defined as very thinabyssal or bathyal facies stratigraphic unit, with extremely low rate of sedimentation andbroad extension at the maximum flooding age. It is an important indicator fordetermination of the maximum flooding event. In recent years, the coneeption ofcondensed section has been opened up in not only its formation depth but also thedistributive scope after the discovery of glauconitic CS in North China Platform inCambrian by the aothors, and the condensed section is defined as the low-rate marinestratigraphic unit formed at the maximum flooding stage. It is the key to age determinationand correlation of craton basinal sequence.
