| Abstract: | The basic concepts of sequence stratigraphy can be applied to any cyclic successions regardless of their origin being marias or nonmarine .The storm base can be taken as the base level at the gentle slope side of a faulted basin for distinguishing the systems tractS as no shelf edge is present in nonmarihe fault6d basins. Most of coatinuous rethetions with high amplitude in seismic sections, misunderstood previously as the boundaries of stratigraphic unit, are maximum flooding surface (MFS)in fact. Abundant and diversified microfossils and nannofossils high content of organic carbon,various authigenic minerals such as glauconie,siderite are concentrated nearby these surfaces. It means that the open sea water invaded iato the faulted basins many times in Cretaceous and Paleogene, which make a restricted environment favourable for oil generation. The trend of lake level changes is similar to that of Haq's curve generally, however, the influence of local movements and autostrahgraphic events have to be colandered. The stratal patterns and models of nonmarine sequence are proposed. |
