Abstract:

On the basis of the previous study and making use of the study on outcrop, well drilling data and paleontology adequately, the characteristics of platformbasin sedimentary system in Qiannanguizhong Sag in Devonian are summed up. Sedimentary system in the basin in Devonian includes mudstone classic turbidity, shalesiliceous rock, siliceous rocklimestone, mudstonemarlite source rock and siliceous rockformation mechanismvolcaniclastic turbidity. Sequence stratigraphy is used to analyze and research the platformbasin system deeply. Sequence boundary always represents as the surface of the change of lithology. And a few boundaries appear erosion surface. Nevertheless, integrated sequence could response to change of sea level.

Key words: Qiannanguizhong Sag, Devonian, platformbasin, sedimentary system, sequence stratigraphy
