原始语种摘要: Abstract(#br)Systematic mass spectrometric 230Th ages are reported for a Porites coral reef terrace from Dengloujiao, Leizhou Peninsula, South China Sea. Seven episodes of coral growth were recognized in this terrace: 7125±96, 6764±29, 5826±37, 5006±54, 2543±24,1915±15, and 1513±22 calendar years before present (cal. aBP). 50% of the coral age population fall between 7200 and 6600 cal. aBP, marking post-glacial stabilization of global sea level. Considering the facts that (i) Dengloujiao reef flat was measured at 1.6–2.5 m above modern tidal datum plane; (ii) modern Porites corals in the South China Sea are living at least ∼1 m below the modern tidal datum plane; (iii) the top 20–30 cm of the reef was eroded; and (iv) crustal subsidence in the region since mid-Holocene was negligible, we...
