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
Hydrous mantle transition zone indicated by ringwoodite included within diamond

TL;DR: X-ray diffraction, Raman and infrared spectroscopic data are reported that provide the first evidence for the terrestrial occurrence of any higher-pressure polymorph of olivine: ringwoodite is included in a diamond from Juína, Brazil, providing direct evidence that, at least locally, the transition zone is hydrous.
Journal ArticleDOI
Carbonates from the lower part of transition zone or even the lower mantle

TL;DR: In this paper, in situ analytical techniques on inclusions in diamonds from Juina (Brazil) originating from the lower part of the transition zone (N580 km) or even the lower mantle (N670 km), reveal the existence of deep Earth carbonates.
Journal ArticleDOI
Three-dimensional trace element analysis by confocal X-ray microfluorescence imaging.

TL;DR: A three-dimensional variant of scanning micro X-ray fluorescence (XRF) is described and evaluated at the ID18F instrument of the European Synchrotron Radiation Facility (ESRF), based on confocal excitation/detection using a polycapillary half-lens in front of the energy-dispersive detector.

TL;DR: The elements Cu, Zn, and Ga appear enriched in this Wild 2 material, which suggests that the CI meteorites may not represent the solar system composition for these moderately volatile minor elements.
