The anatomy of an andesite volcano: a time-stratigraphic study of andesite petrogenesis and crustal evolution at Ruapehu Volcano, New Zealand
(Oxford University Press, 2012)Ruapehu, New Zealand’s largest active andesite volcano, is located at the southern tip of the Taupo Volcanic Zone (TVZ), the main locus of subduction-related volcanism in the North Island. Geophysical data indicate that ... -
An assessment of the mantle and slab components in the magmas of an oceanic arc volcano: Raoul Volcano, Kermadec arc
(Elsevier, 2009)Raoul Volcano occupies a simple oceanic subduction setting in the northern part of the Kermadec arc on the Pacific–Australian convergent plate boundary. The primary inputs to the magmatic system that feeds the volcano are ... -
Forecasting catastrophic stratovolcano collapse: A model based on Mount Taranaki, New Zealand
(Geological Society of America, 2012)Regular large-scale edifice collapse and regrowth is a common pattern during the long lifespans of andesitic stratovolcanoes worldwide. The >130 k.y. history of Mount Taranaki, New Zealand, is punctuated by at least 14 ... -
Growth and magmatic evolution of Tongariro and Raupehu volcanoes, New Zealand
(University of Waikato, Hamilton., 2001)The aim of this excursion is to examine new work on the eruptive and magmatic histories of Tongariro and Ruapehu Volcanoes. By integrating geochemical and isotopic analyses within a well-constrained framework of geochronology ... -
Temporal evolution of a high-k andesitic magmatic system: Taranaki Volcano, New Zealand
(Oxford University Press, 2011)Taranaki (Mt. Egmont) in the western North Island of New Zealand is a high-K andesite volcano with an eruptive history extending over more than 200 kyr. In general, petrological research has concentrated on the post-10 ka ...
