Stratigraphy and Holocene evolution of the mud-dominated Chao Phraya delta, Thailand

River-Dominated Coasts

“…The pattern of landward migration of the narrow mangrove fringe is particularly well recorded from dated cores throughout the central plain of Thailand during the final stages of sea-level rise (Somboon, 1988). The shoreline was north of the location now occupied by the city of Ayuthaya 6000-7000 years ago and has since migrated approximately 100 km southward (Tanabe et al, 2003b;Saito et al, 2007).…”

“…A 300-500-year still-stand of sea level is inferred from Singapore about 7700 years BP, which may have enabled the initiation of the major deltas in the world (Bird et al, 2007). The stratigraphy of the Asian mega deltas records deposition of intertidal or shallow marine sediments unconformably over an eroded Pleistocene alluvial surface or conformably trans gressive estuarine sediments (Tanabe et al, 2003a(Tanabe et al, , 2003b. The penultimate stages of transgression, as sea level rose, were recorded by the deposition of organic muds associated with mangrove forests in intertidal environments, aggrading and onlapping progressively landward.…”

“…Coral reefs, mangrove forests, and beach rocks protect many island coasts from Saito et al, 2001, Hori et al, 2002, Ta et al, 2002, Tanabe et al, 2003a shoreline migration during the last 2000 years average rate (m/y) (Nunn and Mimura, 2005).…”

“…Such depositional settings are still poorly un der stood, but known from re cent and fossil ex am ples (Augustinus, 1980;Hovikoski et al, 2008).
