摘要
Sealevel change, which is an important contents of sedimentary background dynamic field,
is recognized by the features and messages of the direct dynamic field, This paper describes the meter-scale
cycles and the stacking patterns in detail, and the synthetic research on the sealevel change with different frequencies
(orders) are stated. The numerous variations of sealevel change with high- frequency indicate the
driving mechanics of Milankovitch event. The features of cyclic thickness, frequency and cyclic interval of
high -frequency sealevel change are also discussed. Finally, a composite sealevel change model of the North
China Carbonate Platform is given.
