Zusammenfassung:The late Holocene microfauna from the beach-rock of the south Andaman Island has been investigated. The beach-rock fauna reflects the reefal environment of deposition. The occurrence of raised beaches and terraces has been attributed to the neotectonic activity in recent times. C-14 dates indicate that the Wandoor beach-rock is younger (1540–1350 years B.P.) than the Chidyatapu beach rock (4410–3900 years B.P.) indicating at least two phases of neotectonic activity.
