| Abstract: | Primary seismic reflections follow chronostratigraphic (time-stratigraphic) correlation patterns rather than time-transgressive lithostratigraphic (rock-stratigraphic) units, so that it has chronostratigraphic significance. In this paper, chronostratigraphic significance of seismic reflection boundaries has been discussed, and mapping of sequence chron section also has been introduced. Taking the Lower Tertiary seismic chronostratigraphical study in Nanning basin, southern China as an example, its seismic sequence is subdivided and the sequence chron inferred on the basis of the seismic reflection recongnization of the relationship between sedimentary sequence and stratal boundaries. Results suggest that the Wayaocun Formation may belong to EarJy Cretaceous and the Fenghuangshan Formation to Late Cretaceous. |
