The Marquesas Islands show an age progression with the youngest volcanoes occurring at the SE end of the chain. Hiva Oa, a large shield volcano with a caldera truncated on the south side, is the NW-most volcano of the chain with some Pleistocene activity. Potassium-Argon dates range from 2.48-1.58 million years ago (Duncan and Mcdougall 1974). Radiometric ages for Tahuata Island, immediately south of Hiva Oa, are Pliocene.
