within the Nam Con Son Basin, offshore Vietnam:
Relationship to accommodation changes resulting from tectonics, eustasy and sediment flux from the Tibetan Plateau

River system has been an important
siliciclastic source to the Cuu Long and Nam Con Son
Basins (offshore Vietnam)
since middle Miocene time (~15 Ma), although the volume of sediment delivered
has varied significantly over time as a function of continental tectonics, paleoclimate history and eustatic sea-level fluctuations.
Thus, the Neogene stratigraphy of offshore Vietnam provides an important
record for the uplift history of the Tibetan Plateau (where the headwaters of
the modern Mekong
River are located), paleoclimatic history, and the evolution of continental
drainage systems across Southeast Asia.
The overall project goal
is to characterize the Neogene stratigraphic succession and seismic facies
within the Nam Con Son Basin in detail and to relate this stratigraphy to
potential petroleum systems, changes in sediment flux from the Mekong River,
differential tectonic subsidence, and eustatic sea-level fluctuations.
Results from this study
will aid in our understanding of the overall timing of Tibetan Plateau uplift
and erosional unroofing, as well as the relationships
between uplift and climate change. Greater understanding of the Neogene
stratigraphy of offshore Vietnam
will also provide insight into the petroleum systems and drilling risks across
offshore southeast Vietnam.
