Journal ArticleDOI
The Fe and Zn isotope composition of deep mantle source regions: Insights from Baffin Island picrites
Alex J. McCoy-West,Alex J. McCoy-West,J. Godfrey Fitton,Marie-Laure Pons,Marie-Laure Pons,Edward C. Inglis,Helen M. Williams,Helen M. Williams +7 more
TL;DR: In this article, high precision Fe and Zn stable isotope analyses of Baffin Island picrites have been performed, with δ56Fe ranging from −0.03 to 0.28.
Journal ArticleDOI
Petrogenesis and Origins of Mid-Cretaceous Continental Intraplate Volcanism in Marlborough, New Zealand: Implications for the Long-lived HIMU Magmatic Mega-province of the SW Pacific
TL;DR: The Lookout Volcanics represent the oldest samples of this HIMUmagmatic mega-province and are remnants of extensive mid-Cretaceous (98 Ma) intraplate volcanism preserved in South Island, New Zealand, which occurred prior to the rifting of Zealandia from Gondwana.
Journal ArticleDOI
The behavior of iron and zinc stable isotopes accompanying the subduction of mafic oceanic crust: A case study from Western Alpine ophiolites
Edward C. Inglis,Baptiste Debret,Kevin W. Burton,Marc-Albarn Millet,Marie-Laure Pons,C. W. Dale,Pierre Bouilhol,Mark E. Cooper,Geoff Nowell,Alex J. McCoy-West,Helen M. Williams +10 more
TL;DR: In this paper, the chemistry and oxidation state of fluids released during prograde metamorphism of subducted oceanic crust was investigated using metagabbros and metabasalts from the Chenaillet massif, Queyras complex and Zermatt-Saas ophiolite.
Journal ArticleDOI
Extreme persistence of cratonic lithosphere in the southwest Pacific: Paleoproterozoic Os isotopic signatures in Zealandia
TL;DR: A suite of mantle xenoliths was assembled from 12 localities throughout New Zealand, an emergent part of Zealandia, to explore the development of this microcontinent.
Journal ArticleDOI
Extensive crustal extraction in Earth’s early history inferred from molybdenum isotopes
Alex J. McCoy-West,Alex J. McCoy-West,Priyadarshi Chowdhury,Kevin W. Burton,Paolo A. Sossi,Geoff Nowell,J. Godfrey Fitton,Andrew C. Kerr,Peter A. Cawood,Helen M. Williams,Helen M. Williams +10 more
TL;DR: In this paper, the authors present molybdenum isotope data for Archaean komatiites and Phanerozoic komatisites and picrites and demonstrate that their mantle sources all possess subchondritic signatures complementary to the superchondrich continental crust.
