Ubiquitous heterogeneity in the Earth's mantle has been documented by numerous
chemical and isotopic analyses of oceanic basalts. Despite the ever-increasing amount of …

West Antarctica has formed the tectonically active margin between East Antarctica and the
Pacific Ocean for almost half a billion years, where it has recorded a dynamic history of …

Crustal recycling at convergent plate boundaries is essential to mantle heterogeneity.
However, crustal signatures in the mantle source of basaltic rocks above subduction zones …

Volcaniclastic sediments, broadly defined as clastic deposits derived from the transport,
deposition and/or redeposition of the products of volcanic activity, have long been a …

One hypothesis for the origin of alkaline lavas erupted on oceanic islands and in
intracontinental settings is that they represent the melts of amphibole-rich veins in the …

Abstract The Transantarctic Mountains (TAM) are one of Earth's great mountain belts and
are a fundamental physiographic feature of Antarctica. They are continental-scale, traverse a …

Diffuse intraplate volcanism spanning the Cenozoic on the North, South, Chatham,
Auckland, Campbell and Antipodes Islands of New Zealand has produced quartz tholeiitic to …

Here we present the first radiometric age data and a comprehensive geochemical data set
(including major and trace element and Sr–Nd–Pb–Hf isotope ratios) for samples from the …

Abstract The Eocene and Miocene volcanic rocks between the cities of Trabzon and Giresun
in the Eastern Pontides (NE Turkey) erupted as mildly and moderately alkaline magmas …

In order to constrain better the distribution, age, geochemistry and origin of widespread
Cenozoic intraplate volcanism on Zealandia, the New Zealand micro-continent, we report …
