Complete Slice of Impact-melt Breccia NWA 10147

This is a complete slice of NWA 10147 which was cut from the previous offering. An impact-melt breccia, NWA 10147 experienced a large-scale shock event following the hypervelocity collision of a projectile with the surface of a chondritic asteroid. While the projectile vaporized, much of the target silicate melted, producing the charcoal gray areas in evidence. The light-colored clasts in the specimen were shocked, but are largely unmelted and uncommonly well-resolved.

Christie's would like to thank Dr. Alan E. Rubin at the Institute of Geophysics and Planetary Physics, University of California, Los Angeles for his assistance in preparing this catalogue note.
