Eclogites with oceanic crustal and mantle signatures from the Bellsbank kimberlite, South Africa, part 2: Sr, Nd, and O isotope geochemistry
Clive R. Neal,Clive R. Neal,Larry A. Taylor,Larry A. Taylor,Jon P. Davidson,Jon P. Davidson,Peter Holden,Peter Holden,Alex N. Halliday,Alex N. Halliday,Peter H. Nixon,Peter H. Nixon,James B. Paces,James B. Paces,Robert N. Clayton,Robert N. Clayton,Toshiko K. Mayeda,Toshiko K. Mayeda +17 more
TL;DR: In this article, the authors used the Bellsbank kimberlite to define three groups of eclogites: mantle cumulates, metamorphosed products of ancient subducted oceanic crust, and radiogenic 87Sr/S6Sr ratios (0.708-0.710).
Journal ArticleDOI
Formation of metal and silicate globules in Gujba: a new Bencubbin-like meteorite fall
Alan E. Rubin,Gregory W. Kallemeyn,John T. Wasson,Robert N. Clayton,Toshiko K. Mayeda,Monica M. Grady,A. B. Verchovsky,Otto Eugster,Silvio Lorenzetti +8 more
TL;DR: Gujba as mentioned in this paper is a coarse-grained meteorite fall composed of 41 vol% large kamacite globules, 20 vol% light-colored silicate globules with cryptocrystalline, barred pyroxene and barred olivine textures, 39 vol% dark-colored, silicate-rich matrix, and rare refractory inclusions.
Journal ArticleDOI
Oxygen isotope cosmothermometer
TL;DR: In this paper, a model involving isotopic exchange between primordial dust and a cooling solar nebular gas is discussed in terms of variations in oxygen isotopic abundances of meteoritic minerals, chondrules, whole meteorites and planets.
Journal ArticleDOI
Genetic relations between iron and stony meteorites
TL;DR: The main group pallasites and the mesosiderites fall within the oxygen isotope group previously determined for the calcium-rich achondrites (eucrites, howardites and diogenites), consistent with derivation from a common source material, and perhaps a common parent body as discussed by the authors.
Journal ArticleDOI
Oxygen isotope fractionations in muscovite, phlogopite, and rutile
TL;DR: In this article, a series of equations that allow the reduced partition function ratios (β factors) for each of these minerals relative to calcite to be calculated at T > 400 K are presented.
