Main trends of Palau Islands' coastal evolution, identified by air and ground truthing

Abstract

The Palau islands' (Western Carolines, Micronesia) main trends of coastal evolution comprise: rise and submergence of a mid-ocean ridge; four reef building phases (Miocene to Holocene); tilting and uplift; karstification into tropical cockpit karst forms. Extensive mangrove tidal flats are also developed. Their sediments as well as the well developed bioerosive notches on the rock islands indicate a remarkable stability in an area of seismic activity and active subduction.
