Abstract
West Maui's rejuvenated-stage Lahaina Volcanics were erupted from four discrete sites. New KAr ages indicate two pulses of volcanism, the older about 0.6 Ma and the younger about 0.4 Ma. Compositionally the lava flows are entirely basanitic, but each pulse is diverse. The underlying postshield-stage Honolua Volcanics were emplaced by about 1.2 Ma on the basis of previously published ages. Therefore the duration of volcanic quiescence prior to rejuvenation is about 0.6 m.y. at West Maui, much longer than estimated previously. ?? 2002 Elsevier Science B.V. All rights reserved.
