| The islands of Nguna, Pele, and Emau, north of Vate Island (also known as Efaté), have been variously mapped as Pleistocene and Pleistocene to Holocene. Late-Pleistocene to Holocene eruptions constructed composite basaltic cones with well-preserved craters. Largely submarine calderas north of Vate Island of varying sizes have been inferred, ranging from a large caldera whose southern rim is defined by the islands of Nguna, Pele, and Emao to a smaller caldera, but their submarine morphology is difficult to define. Pumiceous deposits of the Efaté Pumice Formation cover much of Vate (Efaté) Island and record a major trachydacitic explosive eruption about 1 million years ago that originated from a submarine vent somewhere north of the island. | |||
