Dating of Soils on the Raised Coral Reef Terraces of Kikai Island in the Ryukyus, Southwest Japan: With Special Reference to the Age of Red-Yellow Soils

摘要

Absolute ages of soils developed on the raised coral reef terraces in Kikai Island were estimated by using the mean rate of tectonic uplift and glacio-eustatic curve during late Quaternary. The results obtained are as follows: State of bare rock outcrop continues for ca. 1.5ka after the emergence, and it takes ca. 3.0ka to develop Lithosols.
