Seismic Velocity, Stratigraphy and Acoustic Study of the South China Sea

Abstract

Our long term goal is to understand the tectonic processes that govern the formation of rifted passive margins, in particular the role of upper crustal faulting versus lower crustal flow. In addition we hope to understand what governs the accumulation of sediment on the shelf and upper slope and specifically in the case of the South China Sea how this is related to growth and erosion of the Himalayas and Tibet. We wish to establish the nature of the stratigraphy on the South China Shelf and upper slope through interpretation of multichannel seismic lines and tie in age information from existing petroleum exploration wells. Most importantly we have mapped the structure of the basement and sedimentary cover in three dimensions using the stacking velocities derived from released MCS profiles, which have been used to map the depth to crucial velocity intervals over the width of the shelf. This data was then merged with the existing data set of Dennis Hayes to provide a comprehensive survey of the region.
