Abstract Coral microatolls have been long used as precise indicators of past sea level. but their use for precise definition of detailed sea-level fluctuations is still rare. Here we report twelve high-precision thermal ionization mass spectrometric Th-230 ages for twelve rims of five mid-Holocene microatolls from all emerged reef terrace at Leizhou Peninsula, northern South China Sea. This is a tectonically stable area, enabling Lis to reconstruct both the timing and trajectory of local sea-level fluctuations accurately. The elevations of these microatoll rims and cores were accurately determined relative to the surface of modern livin., microatolls at the same site. The results indicate that the sea level during, the period of 7050-6600 yr bp (years before AD 1950) Was about 171 to 219 cm above the present, With at least four Cycles of fluctuations. Over this 450 yr interval, sea level fluctuated by 20-40 cm on century scales. Crown Copyright (c) 2009 Published by University of Washington. All rights reserved.
