Sequence stratigraphy of south central coastal quaternary sandy formation and stratigraphic significance

The South Central Coastal Quaternary sandy formation has been studied by many authors according to different objectives, mainly for establishing quaternary geological maps ata different scale. There are 5 sedimentary cycles established based on the absolute age of the sand, that was analyzed by the method of thermoluminescent dating of quartz, and by the comparison between 5 global glacial/interglacialcycles and 5 sedimentary cycles of the Red River Delta.
