Research Abstract |
We examined the occurrences of various landforms constituting coastal plains, the relation of postglacial coastal landforms to those of the last interglacial, Holocene coastal developments and sea-level changes in Rarotonga, Aitutaki and Mangaia islands, Cook Islands, on the basis of the investigation of landforms and sediments of coastal plains and coral reefs. In Rarotonga focused in this study, after sea level attained present sea level c. 5,000-6,000 years ago, coastal plains have generally emerged since c. 4,000-5,000 years ago.
