A Drowned Miocene Terrace in the Hawaiian Islands

Abstract

A highly fossiliferous sample dredged in September 1961 from a submerged terrace at a depth of 500 to 520 meters off Honolulu contains a reef fauna suggesting deposition at depths of 10 meters or less. The corals and pelagic foraminifers indicate a probable Miocene age. The Hawaiian rise was in existence prior to that time, and the submarine terrace and associated reef were subsequently submerged to their present position.
