Then thepaper proposes a series of new concepts for chemical sequence stratigraphy, including the con-densation surface, relative compaction factor and time missing factor. Finally a quantitativecurve of Late Permian relative sea-level change in the Ziyun area is presented with timecoordinates. 关 键 词：chemical sequence stratigraphy HIATUS SURFACE REEF on platform margin TIME MISSING factor relative SEA-LEVEL change
