Abstract In Vietnam, the coastal sand barriers and dunes located in front of the steep slopes
of the high rising Truong Son Mountains are sensitive to climate and environment change
and give evidence for Holocene sea-level rise. The outer barrier sands were deposited
shortly before or contemporaneous with the local sea-level high stand along the Van Phong
Bay postdating the last glacial maximum (LGM). Optically stimulated luminescence (OSL)
dating yielded deposition ages ranging from 8.3±0.6 to 6.2±0.3 ka for the stratigraphically ...
