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
Kimberlites reveal 2.5-billion-year evolution of a deep, isolated mantle reservoir
Jon Woodhead,Janet M. Hergt,Andrea Giuliani,Andrea Giuliani,Andrea Giuliani,Roland Maas,David Phillips,D. Graham Pearson,Geoff Nowell +8 more
TL;DR: Gl Globally distributed kimberlites have their origins in a single, homogeneous early Earth reservoir that was subsequently perturbed, probably by subduction along the margins of Pangaea, around 200 million years ago, revealing a long-lived and globally extensive mantle reservoir that underwent subsequent disruption.
Journal ArticleDOI
Sr isotope analysis of bird feathers by TIMS: a tool to trace bird migration paths and breeding sites
TL;DR: In this paper, the Sedge Warbler (Acrocephalus schoenobaenus) feathers were used from four different locations within Europe and the shaft and the vane parts of the feather were analysed separately.
Journal ArticleDOI
Origin of CFB Magmatism: Multi-tiered Intracrustal Picrite^Rhyolite Magmatic Plumbing at Spitzkoppe, Western Namibia, during Early Cretaceous Etendeka Magmatism
Robert N. Thompson,A. J. V. Riches,P.M. Antoshechkina,D.G. Pearson,Geoff Nowell,Chris J. Ottley,Alan P. Dickin,Vicky Hards,A.-K. Nguno,V. Niku-Paavola +9 more
TL;DR: Early Cretaceous tholeiitic picrite-to-rhyolite dykes around Spitzkoppe, western Namibia, are part of the extensive Henties Bay-Outjo swarm, penecontemporaneous with 132 Ma Etendeka lavas 100 km to the NW as mentioned in this paper.
Journal ArticleDOI
From source to crust: Tracing magmatic evolution in a kimberlite and a melilitite using microsample geochemistry
J. Malarkey,D.G. Pearson,Bruce A. Kjarsgaard,Jon P. Davidson,Geoff Nowell,Chris J. Ottley,J. Stammer +6 more
TL;DR: In this paper, an integrated micro-sampling trace element and isotopic study of primary minerals within the Jos kimberlite, Canada, in order to observe how different phases record progressive crustal interaction in the evolving kimbersite.
