High Resolution Seismic for sequence stratigraphy interpretation of shallow sediments in the center Continental Shelf of Vietnam

Abstract

Seismic stratigraphy analysis based on sequence stratigraphy has been developed strongly over the world. However, due to differences in development system of sedimentary basins, the analysis is different from place to place. In this paper, the authors will present seismic stratigraphy interpretation of sequence stratigraphy on shallow sediments of continental shelf of Vietnam, using HRS, determining the sedimentary system tracts and sequences in 4rd or 5th order, the relationship between sedimentary cycles, sea level change and tectonic movement, facial-paleogeographic characteristics and geological development history of Pliocene-Quaternary in the area. The interpreted seismic stratigraphic features assisted in defining the gross depositional environments, the relative sea level changes, shale/sand ratios, and locations of carbonate reefs and igneous rocks in the area
