|The isolated, uninhabited Antipodes Islands are located in the south Pacific, 770 km SE of New Zealand. Volcanism has been dominantly pyroclastic, and the presence of well-preserved scoria cones suggests a Holocene age (LeMasurier and Thomson, 1990). The most recent eruptions occurred on the cone forming Mount Galloway and Mount Waterhouse at the center of 4-km-wide Antipodes Island. Marine erosion has exposed sections through tuff cones at Perpendicular Head and Albatross Point at the NE and SE tips of the island, respectively. Radiometric dates indicated basalts that are younger than 1 million years, and Mullen (1969) also noted that volcanism may have continued until Recent times.|
