Macroscopic Description: Kathleen McBride Thin Section (EET96314,2; 96331,4) Description: Tim McCoy
The sections consist of an aggregate of large olivine grains up to 1 mm across with numerous areas of finer-grained (~200m m), equigranular olivine, pigeonite and augite with abundant 120° triple junctions. Individual grains are rimmed by carbon-rich material containing traces of metal. Shock effects are numerous, including undulatory extinction, polysynthetic twinning and kink banding. Olivines have cores of Fa12-13, with rims reduced to Fa2. Pigeonite (Fs11Wo4) and augite (Fs7Wo29) are relatively homogeneous. These meteorites are paired ureilites and may be paired with EET96293. | ||||||||||||||||||||
