Plio-Pleistocene intra-plate magmatism from the southern Sulu Arc, Semporna peninsula, Sabah, Borneo: Implications for high-Nb basalt in subduction zones
Colin G. Macpherson,Colin G. Macpherson,Kai Kim Chiang,Robert Hall,Geoff Nowell,Paterno R. Castillo,Matthew F. Thirlwall +6 more
TL;DR: In this paper, major and trace element concentrations and isotopic ratios for Plio-Pleistocene basalts and basaltic andesites from the Semporna peninsula in Sabah, Borneo, at the southern end of the Sulu Arc were analyzed.
Journal ArticleDOI
Evidence of diverse depletion and metasomatic events in harzburgite–lherzolite mantle xenoliths from the Iberian plate (Olot, NE Spain): Implications for lithosphere accretionary processes
Gianluca Bianchini,Luigi Beccaluva,Costanza Bonadiman,Geoff Nowell,Graham Pearson,Franca Siena,Marjorie Wilson +6 more
TL;DR: In this paper, a bi-modal suite of spinel spinel lherzolites and spinel harzburgites from the Olot volcanic district (NE Spain) was studied and it was shown that these two genetically different, but adjoining, mantle domains intimately mingled along the northern Iberian margin during the subsequent plate convergence processes.
Journal ArticleDOI
Precise and accurate 186Os/188Os and 187Os/188Os measurements by multi-collector plasma ionisation mass spectrometry (MC-ICP-MS) part I: Solution analyses
TL;DR: In this paper, an improved and robust method for the derivation of interfering element isotope ratios is presented and evaluated via analysis of solutions with widely varying interfering element/analyte ratios.
Journal ArticleDOI
Precise and accurate 186Os/188Os and 187Os/188Os measurements by Multi-collector Plasma Ionisation Mass Spectrometry, part II: Laser ablation and its application to single-grain Pt–Os and Re–Os geochronology
TL;DR: Nowell et al. as discussed by the authors showed that the mass bias effects for Os isotope ratios during LA-MC-ICP-MS are similar in nature and magnitude to mass bias variations observed during normal solution-mode analysis.
Journal ArticleDOI
Combining CSD and isotopic microanalysis : magma supply and mixing processes at Stromboli Volcano, Aeolian Islands, Italy.
Daniel J. Morgan,Daniel J. Morgan,Daniel J. Morgan,Dougal A. Jerram,D. G. Chertkoff,Jon P. Davidson,D.G. Pearson,A. Kronz,Geoff Nowell +8 more
TL;DR: In this article, the ICSD plots were used to study the evolution of a 26,000 year old sample from Stromboli Volcano and associated isotopic microanalysis of the phenocrysts.
