A/B |
The exterior of this ureilite has a black, rough fusion crust most of which has weathered. The interior is a dark crystalline sugary texture with some rust. Some metal grains are present. There are light colored inclusions with minor rust. |
The section consists of an aggregate of olivine grains up to 2 mm across. Individual grains are rimmed by moderately weathered carbon-rich material containing traces of metal and troilite. Olivine grains exhibit undulatory extinction. Olivines, both cores and rims are relatively homogeneous at Fa14-15. The meteorite is a ureilite. |
This sample is paired with EET 87511 in 2020 by K. Righter based on field locations, textural similarities, and olivine minor and major element compositions (Goodrich, 2001, LPSC abstract, #1300; Downes et al., 2008, Geochim. Cosmochim. Acta 72(19), 4825-4844). |
