Sm-Nd isotopic evolution of chondrites

TL;DR: In this paper, it was shown that none of the analyzed meteorite samples deviated more than 0.5 e-units from a 4.6-AE reference isochron and defined an initial 4.5-AE value for CHUR using the Juvinas data of Lugmair.
Journal ArticleDOI

Comet 81P/Wild 2 under a microscope.

Donald E. Brownlee, +185 more
- 15 Dec 2006 - 
TL;DR: The Stardust spacecraft collected thousands of particles from comet 81P/Wild 2 and returned them to Earth for laboratory study, and preliminary examination shows that the nonvolatile portion of the comet is an unequilibrated assortment of materials that have both presolar and solar system origin.
Journal ArticleDOI

Nd and Sr isotopic systematics of river water suspended material: implications for crustal evolution

TL;DR: In this article, the average Sm-Nd and Rb-Sr isotope parameters for the upper continental crust today are refined using a model of the North American continental surface.
Journal ArticleDOI

Precise determination of SmNd ratios, Sm and Nd isotopic abundances in standard solutions☆

TL;DR: In this article, the methods used for precise calibrations of Sm/Nd ratios and the average isotopic abundances obtained for normal Sm and Nd are given, and a mixed Sm-Nd normal solution with a precisely known Sm/nd ratio close to the nominal average chondritic value is described and the calibration discussed.
Journal ArticleDOI

Chicxulub Crater: A possible Cretaceous/Tertiary boundary impact crater on the Yucatán Peninsula, Mexico

TL;DR: In this article, the authors suggest that a buried 180 km-diameter circular structure on the Yucatan Peninsula, Mexico, is an impact crater, which is revealed by magnetic and gravity-field anomalies, as well as by oil wells drilled inside and near the structure.
