Along the coast extending from Khánh Ḥa to Ninh
Thuận there are many markers of activities during the Quaternary. In many
places marine terraces are exposed, with hard sedimentary rocks recording the marks of ancient shoreline of Holocene age.
This paper presents the characteristics of
topography, petrography and chemical composition of sediments in these terraces, that show the formation of marine terraces related
to the dynamic process of shallow sea.
The age of these marine terraces was determined as
5,150 ± 150 year BP, corresponding to the Flandrian marine transgression with
the maximum in the Middle Holocene.
