Journal ArticleDOI
High precision Hf isotope measurements of MORB and OIB by thermal ionisation mass spectrometry: insights into the depleted mantle
Geoff Nowell,Geoff Nowell,Pamela D. Kempton,Stephen R. Noble,J. G. Fitton,Ad D. Saunders,John J. Mahoney,Rex N. Taylor +7 more
TL;DR: In this article, the authors show that NMORB and the depleted MORB mantle reservoir are characterised by a similarly limited range in / ratios and suggest that the high / MORB-like basalts may ultimately be related to mantle plumes and represent melts of a depleted component entrained by the plumes.
Journal ArticleDOI
Hf-Nd Element and Isotope Perspective on the Nature and Provenance of Mantle and Subduction Components in Western Pacific Arc-Basin Systems
TL;DR: In this article, the authors used the integrated study of Hf-Nd element and isotope covariations to define the nature and provenance of the mantle and subduction inputs to subduction systems.
Journal ArticleDOI
Common-Pb corrected in situ U–Pb accessory mineral geochronology by LA-MC-ICP-MS
Matthew S.A. Horstwood,Gavin L. Foster,Gavin L. Foster,Randall R. Parrish,Randall R. Parrish,Stephen R. Noble,Geoff Nowell +6 more
TL;DR: In this paper, the LA-MC-ICP-MS is used for the determination of U-Pb ages of accessory minerals using a raster ablation protocol and an external ablation standard used to quantify an overall error.
Journal ArticleDOI
Magmatism Associated with Orogenic Collapse of the Betic–Alboran Domain, SE Spain
TL;DR: In this article, the authors provide insights into the relationships between the thermal and wholesale delamination at the Moho, slab detachment or slab rollmechanical state of the lithosphere during late orogenesis.
Journal ArticleDOI
Hf Isotope Systematics of Kimberlites and their Megacrysts: New Constraints on their Source Regions
Geoff Nowell,D.G. Pearson,David R. Bell,Richard W. Carlson,C. B. Smith,Pamela D. Kempton,Stephen R. Noble +6 more
TL;DR: Kimberlites from Southern Africa, along with their low-Cr megacrysts, have unusual Hf-Nd isotopic characteristics as discussed by the authors, with negative Hf values varying from −1.2 to −10.1.
