Taken as an example the Upper Permian reef section on the carbonate platform margin at Ziyun, Guizhou, the paper discusses the missing time of a hiatus surface, an important problem in chemical sequence stratigraphy, with the concept of cosmic chemistry. Then the paper proposes a series of new concepts for chemical sequence stratigraphy, including the condensation surface, relative compaction factor and time missing factor. Finally a quantitative curve of Late Permian relative sea–level change in the Ziyun area is presented with time coordinates.
