New stratigraphic unit - The Early Holocene Binh Dai formation at the Estuary and coastal area of Cuu Long delta
The Binh Dai Formation was established by analysis results of the BT3 borehole of KC09.06/06- 10 project, in Ba Tri commune - Binh Dai district of Ben Tre province. The sedimentary of Binh Dai Formation has identified Early Holocene age that was formed at the coastal estuarine environment
