238U230Th disequilibria, magma petrogenesis, and flux rates beneath the depleted Tonga-Kermadec island arc
Simon Turner,Chris J. Hawkesworth,Nick Rogers,Jessica M. Bartlett,Tim J. Worthington,Janet M. Hergt,Julian A. Pearce,Ian E. M. Smith +7 more
TL;DR: In this article, high precision TIMS uranium, thorium, strontium, neodymium, and lead isotopes, along with complete major and trace element data, have been obtained on an extensive sample set comprising fifty-eight lavas along the arc as well as nineteen samples of the subducting sediments at DSDP site 204 just to the east of the Tonga-Kermadec trench.
Journal ArticleDOI
Caldera Volcanoes of the Taupo Volcanic Zone, New Zealand
TL;DR: The central TVZ has been active since 2 Ma and has erupted >104 km3 of dominantly rhyolitic magma during the last 1 m.y.p as mentioned in this paper.
Journal ArticleDOI
Geology of Eastern Papua
Hugh L Davies,Ian E. M. Smith +1 more
TL;DR: The Papuan ultramafic belt is a southeasterly trending mountainous peninsula with islands to the east and southeast, between 7° to 12° S. and 146° to 155° E. as mentioned in this paper.
Journal ArticleDOI
An integrated model for the temporal evolution of andesites and rhyolites and crustal development in New Zealand's North Island
Richard C. Price,John A. Gamble,Ian E. M. Smith,Robert B. Stewart,Stephen Eggins,Ian C. Wright +5 more
TL;DR: In this paper, it was shown that andesites are generated through the interaction of mantle-derived magmas with lower crustal melts and restites and differences between Ruapehu and Taranaki andesite reflect contrasting physical conditions during melting as well as subtle variations in the mantle and crustal source compositions.
Journal ArticleDOI
Petrology and petrogenesis of volcanic rocks from the Taupo Volcanic Zone: a review
TL;DR: In this paper, the authors used least-squares mixing models using geochemistry and a variety of stable and radiogenic isotopes show that TVZ rhyolite could be generated by AFC of a mafic parent.
