Journal ArticleDOI
Disequilibrium melting during crustal anatexis and implications for modeling open magmatic systems
TL;DR: In this paper, a suite of volcanic rocks and entrained crustal xenoliths from the Central Andes using bulk geochemical compositions for mantle-derived and crustal end-members was investigated and modeled for a suite with respect to the continental crust.
Journal ArticleDOI
Moving peoples, changing diets: Isotopic differences highlight migration and subsistence changes in the Upper Mun River Valley, Thailand
Charlotte L. King,R. Alexander Bentley,Nancy Tayles,Una Strand Viðarsdóttir,Geoff Nowell,Colin G. Macpherson +5 more
TL;DR: In this paper, the authors used isotope analysis to examine the human skeletal remains from Ban Non Wat, northeast Thailand, to give insight into patterns of migration and subsistence strategy during prehistory.
Journal ArticleDOI
Quantitative analysis of trace element concentrations in some gem-quality diamonds.
J. McNeill,D.G. Pearson,Ofra Klein-BenDavid,Ofra Klein-BenDavid,Geoff Nowell,Chris J. Ottley,I. Chinn +6 more
TL;DR: A new ICPMS-based (ICPMS: inductively coupled plasma mass spectrometry) method for the analysis of trace element concentrations within fluid-poor, gem-quality diamonds is presented, providing some supporting evidence of a link between the parental fluids for both fluid-inclusion-rich and gem diamonds.
Journal ArticleDOI
Isotopic investigation of diet and residential mobility in the Neolithic of the Lower Rhine Basin.
TL;DR: In this article, carbon and nitrogen isotope analyses of European Mesolithic and Neolithic populations showed a shift in diet from the Mesolithic to the Neolithic, but also great variety in Neolithic diets, several of which incorporate fish.
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.
