Journal ArticleDOI
Widespread 54Cr Heterogeneity in the Inner Solar System
TL;DR: In this article, the authors report systematic deficits in 54Cr relative to Earth in differentiated molten planetesimals (the parent bodies of eucrites, diogenites, mesosiderites, pallasites, angrites, and Mars) and even in some chondritic material (ordinary chondrites).
Journal ArticleDOI
High-precision 142Nd/144Nd measurements in terrestrial rocks : Constraints on the early differentiation of the Earth's mantle
TL;DR: In this paper, the authors used Triton mass spectrometer to detect anomalous 142 Nd/ 144 Nd ratios of early Archean rocks. But their results were limited to the 3.6 to 3.8 Ga West Greenland craton.
Journal ArticleDOI
146Sm-142Nd evidence from Isua metamorphosed sediments for early differentiation of the Earth's mantle.
TL;DR: C coupled isotopic calculations, combined with an initial ɛ143Nd value from ref. 6, constrain the mean age of mantle differentiation to 4,460 ± 115 Myr, which probably reflects differentiation of the Earth's mantle during the final stage of terrestrial accretion.
Journal ArticleDOI
53Mn–53Cr systematics of the early Solar System revisited
Anne Trinquier,Anne Trinquier,Jean-Louis Birck,Claude J. Allègre,Christa Göpel,David Ulfbeck +5 more
TL;DR: In this article, the authors investigated the Mn-Cr systematics in a number of primitive meteorites, differentiated planetesimals and terrestrial planets in order to address the chronology of the early stages of protoplanetary disk evolution and planetary formation.
Journal ArticleDOI
Osmium-strontium-neodymium-lead isotopic covariations in mid-ocean ridge basalt glasses and the heterogeneity of the upper mantle
TL;DR: Osmium, strontium, neodymium, and lead isotopic data have been obtained for 30 hand picked samples of basaltic glass from the Pacific, Atlantic and Indian mid-oceanic ridges as mentioned in this paper.
