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

Mineralogy and petrology of comet 81P/wild 2 nucleus samples

Michael E. Zolensky, +75 more
- 15 Dec 2006 - 
TL;DR: The bulk of the comet 81P/Wild 2 samples returned to Earth by the Stardust spacecraft appear to be weakly constructed mixtures of nanometer-scale grains, with occasional much larger ferromagnesian silicates, Fe-Ni sulfides,Fe-Ni metal, and accessory phases.

Thermal Metamorphism in Chondrites

TL;DR: In this paper, the authors summarize metamorphic changes in chondritic meteorites and discuss temperatures, oxidation states, and possible heat sources for metamorphism, and discuss the conditions under which chondrites originally formed.
Journal ArticleDOI

The onset of metamorphism in ordinary and carbonaceous chondrites

TL;DR: In this paper, a variety of metamorphic effects were noted and subjected to detailed analysis using electron microprobe, scanning electron microscopy (SEM), TEM, and cathodoluminescence (CL) methods.
Journal ArticleDOI

Highly siderophile elements in chondrites

TL;DR: The abundances of the highly siderophile elements (HSE), Re, Os, Ir, Ru, Pt and Pd, were determined by isotope dilution mass spectrometry for bulk samples of 13 carbonaceous chondrites, 13 ordinary chondites and 9 enstatite chondrite as discussed by the authors.
