    Non-chondritic magnesium and the origins of the inner terrestrial planets by Wiechert, U, Halliday, A

    Published 2007
    “…High-precision magnesium (Mg) isotope data obtained using a large geometry high resolution MC-ICPMS are reported for 9 carbonaceous and ordinary chondrites, 9 eucrites and diogenites generally considered to originate from Asteroid 4 Vesta, together with 4 martian meteorites, and a variety of terrestrial and lunar materials. …”

    Search for nucleosynthetic and radiogenic tellurium isotope anomalies in carbonaceous chondrites by Fehr, M, Rehkaemper, M, Halliday, A, Schoenbaechler, M, Hattendorf, B, Guenther, D

    Published 2006
    “…Tellurium isotope data acquired by multiple-collector inductively coupled plasma-mass spectrometry (MC-ICPMS) are presented for sequential acid leachates of the carbonaceous chondrites Orgueil, Murchison, and Allende. Tellurium isotopes are produced by a broad range of nucleosynthetic pathways and they are therefore of particular interest given the isotopic anomalies previously identified for other elements in these meteorites. …”

    Chondrule sizes within the CM carbonaceous chondrites and measurement methodologies by Floyd, CJ, Benito, S, Martin, P, Jenkins, LE, Dunham, E, Daly, L, Lee, MR

    Published 2024
    “…Many of the recently reported sizes of chondrules within the CM carbonaceous chondrites differ significantly from the established literature average and are more closely comparable to those of chondrules within CO chondrites. …”

    Fluid flow in chondritic parent bodies: Deciphering the compositions of planetesimals by Young, E, Ash, R, England, P, Rumble, D

    Published 1999
    “…Down-temperature flow of aqueous fluid within planetesimals is sufficient to explain the mineralogical and oxygen isotopic diversity among CV, CM, and Cl carbonaceous chondrites and displacement of the terrestrial planets from the primordial slope 1.00 line on the oxygen three-isotope plot.…”

    Nucleosynthetic zirconium isotope anomalies in acid leachates of carbonaceous chondrites by Schonbachler, M, Rehkamper, M, Fehr, M, Halliday, A, Hattendorf, B, Gunther, D

    Published 2005
    “…Stepwise dissolutions of the carbonaceous chondrites Orgueil (CI), Murchison (CM) and Allende (CV) reveal large nucleosynthetic anomalies for Zr isotopes that contrast with the uniform compositions found in bulk meteorites. …”

    Super-chondritic Sm/Nd ratios in Mars, the Earth and the Moon. by Caro, G, Bourdon, B, Halliday, A, Quitté, G

    Published 2008
    “…This chronology, however, assumes that the composition of the total planet is identical to that of primitive undifferentiated meteorites called chondrites. The difference in the 142Nd/144Nd ratio between chondrites and terrestrial samples may therefore indicate very early isolation (<30 Myr from the formation of the Solar System) of the upper mantle or a slightly non-chondritic bulk Earth composition. …”

    Published 2021
    “…One phase that formed during this alteration was magnetite, and its morphology and abundance vary between and within chondrite groups, providing a means of investigating chondrite aqueous alteration. …”
