Evidence for K-rich terranes on Vesta from impact spherules
The howardite-eucrite-diogenite (HED) clan is a group of meteorites that probably originate from the asteroid Vesta. Some of them are complex breccias that contain impact glasses whose compositions mirror that of their source regions. Some K-rich impact gl ...
2009Young chondrules in CB chondrites from a giant impact in the early Solar System
Chondrules, which are the major constituent of chondritic meteorites, are believed to have formed during brief, localized, repetitive melting of dust ( probably caused by shock waves(1,2)) in the protoplanetary disk around the early Sun. The ages of primit ...
2005Cristobalite inclusions in the Tatahouine achondrite: Implications for shock conditions
The mineralogy of the Tatahouine diogenite was investigated by optical microscopy, Raman micro-spectrometry, and scanning and transmission electron microscopies. Inclusions of alpha-cristobalite in orthopyroxenes, locally in symplectic association with chr ...
