对马尔代夫碳酸盐台地的活塞岩心进行了碳酸盐矿物学、粒度分布、碳酸钙含量和有机碳的研究。沉积记录与晚更新世海平面变化有关,使用基于从浮游有孔虫、超微化石生物地层学和14 C年龄测定中获得的氧同位素的年龄模型。沉积记录与晚更新世海平面之间的相关性表明,过去15万年来文石和泥的变化明显与马尔代夫碳酸盐台地环礁主要泻湖的洪水和海底暴露有关。  平台洪水事件的特点是强烈增加沉积的文石和泥在马尔代夫内海。相反,暴露事件可以通过两个代理记录值的快速下降来识别。结果表明,马尔代夫碳酸盐台地上的沉积物包含更新世海平面变化的连续记录。因此,这些沉积物可能有助于更好地了解区域甚至全球海平面变化,并对洋流和碳酸盐台地形态之间的相互作用产生新的见解。
A piston core from the Maldives carbonate platform was investigated for carbonate mineralogy, grain‐size distributions, calcium carbonate content and organic carbon. The sedimentary record was linked to Late Pleistocene sea‐level variations, using an age model based on oxygen isotopes obtained from planktonic foramanifera, nannofossil biostratigraphy and14C age determinations. The correlation between the sedimentary record and Late Pleistocene sea‐level showed that variations in aragonite and mud during the past 150 000 years were clearly related to flooding and sea floor exposure of the main lagoons of the atolls of the Maldives carbonate platform. Platform flooding events were characterized by strongly increased deposition of aragonite and mud within the Inner Sea of the Maldives. Exposure events, in contrast, can be recognized by rapid decreases in the values of both proxy records. The results show that sediments on the Maldives carbonate platform contain a continuous record of Pleistocene sea‐level variations. These sediments may, therefore, contribute to a better understanding of regional and even global sea‐level changes, and yield new insights into the interplay between ocean currents and carbonate platform morphology.
