What is Sequence biostratigraphy of the late Oligocene to Miocene succession in the northern Song Hong Basin, offshore Vietnam about?
The Cenozoic sedimentary succession of the Song Hong Basin, offshore North Vietnam is poor in marine microfossils, especially in the early Miocene and Oligocene and subsequently is poorly dated. However, it is rich in terrestrially derived pollen, spores, and freshwater algae. Biostratigraphic assemblages from two wells, termed Well A and B, have been evaluated using the approach of sequence biostratigraphy. The Oligocene fluviolacustrine succession through the Dinh Cao Formation displays multiple transgressive-regressive cycles comparable with those reported from the Cuu Long Basin to the south. By applying the local Cuu Long Oligocene palynological zonation (CLO zones), these cycles can be correlated directly with the cycles from the Cuu Long Basin, showing that sedimentation began during sequence 19, at about 29 Ma or a little earlier off-structure, over basement. The deepest interval within Well A yielded abundant pollen of the montane tree Alnus, and with the position of the basin within the northern tropics at 20 o N, this suggests that in the mid Oligocene, the basin was intermontane, with Alnus widespread in swamps after the lake shallowed, at an altitude of at least 1000 m
