Abstract:

Soc Trang-Bac Lieu area belongs to the Mekong River delta. It is also considered to be strongly affected by climate change and rising sea levels. The Holocene deglaciatial accelerated transgression, leading to a rapid formation of shallow marine and coastal sediments, which overly the pre-existing continental sediments across the Mekong River delta. Foraminifera is the microfossil group, which is widely found in marine sediment and is commonly used to interpret the depositional environment, stratigraphic and paleo-geography. This study presents new results of this microfossil group in the Pleistocene-Holocene derived from 20 sediment samples from two drill holes in the Soc Trang-Bac Lieu area. Based on their composition and morphology, we identified a total of 33 species, belonging to 18 genras, 11 families and 4 suborders Foraminifera namely Rotaliina Delage et Hérouard, 1896; Miliolina Delage et Hérouard, 1896; Textulariina Delage et Hérouard, 1896 and Lagenina Delage et Hérouard, 1896. All of the obtained Foraminifera indicate that their morphology and anatomical characteristics characterize estuarine and shallow marine environments, where they demonstrate strong hydrodynamic regimes and wide variation of salinity and temperature.
