Journal ArticleDOI
The Amount of Recycled Crust in Sources of Mantle-Derived Melts
Alexander V. Sobolev,Albrecht W. Hofmann,D. V. Kuzmin,Gregory M. Yaxley,Nicholas Arndt,Sun-Lin Chung,Leonid V. Danyushevsky,Tim Elliott,Frederick A. Frey,Michael O. Garcia,Andrey A. Gurenko,Vadim S. Kamenetsky,Andrew C. Kerr,Nadezhda Krivolutskaya,Vladimir V. Matvienkov,Igor K. Nikogosian,Igor K. Nikogosian,Alexander Rocholl,I. A. Sigurdsson,N. M. Sushchevskaya,Mengist Teklay +20 more
TL;DR: Olivine phenocrysts' compositions record differences in the contributions of pyroxenite-derived melts in mid-ocean ridge basalts, which imply involvement of 2 to 20% (up to 28%) of recycled crust in mantle melting.
Journal ArticleDOI
Temperatures in Ambient Mantle and Plumes: Constraints from Basalts, Picrites, and Komatiites
Claude Herzberg,Paul D. Asimow,Nicholas Arndt,Yaoling Niu,C. M. Lesher,J. G. Fitton,Michael J. Cheadle,Ad D. Saunders +7 more
TL;DR: In this paper, a new evaluation is made of parental magma compositions that would crystallize olivines with the maximum forsterite contents observed in lava flows, consistent with the plume model.
Journal ArticleDOI
Role of recycled oceanic basalt and sediment in generating the Hf–Nd mantle array
TL;DR: In this paper, the authors model the hafnium and neodymium isotopic composition of oceanic basalts as a mixture of recycled oceanic crust and depleted mantle and find that recycling of basalt alone is not sufficient to reproduce the mantle array.
Journal ArticleDOI
Linking mantle plumes, large igneous provinces and environmental catastrophes
Stephan V. Sobolev,Alexander V. Sobolev,D. V. Kuzmin,Nadezhda Krivolutskaya,Alexey G. Petrunin,Nicholas Arndt,Viktor A. Radko,Yuri R. Vasiliev +7 more
TL;DR: This paper presented petrological evidence for a large amount of dense recycled oceanic crust in the head of the plume and developed a thermomechanical model that predicts no pre-magmatic uplift and requires no lithospheric extension.
Journal ArticleDOI
Crustal growth in West Africa at 2.1 Ga
TL;DR: The most precise zircon U-Pb and Sm-Nd data for the more widespread Birimian terranes (sensu stricto), from this study and from the literature, cluster between 2.12 and 2.07 Ga.
