Shiny black fusion crust covers ~75% of the exterior. The exposed surface is gray with black shiny white and yellow inclusions ~1 mm in size. The interior has a light gray matrix with white and black crystals throughout. |
This meteorite is dominated by course-grained (up to 2 mm average grain size) pyroxene and plagioclase in a brecciated matrix with occasional polymineralic clasts (up to 2.5 mm in maximum dimension). Pyroxenes are exsolved (Fs48-58Wo5-17) and plagioclase (An88-89Or0.5). The Fe/Mn ratio of the pyroxene is ~29. The meteorite is a brecciated eucrite. |
MIL 11041, 11291, 13079, and 15080 all paired based on young ages for 11291 and 15080, as well as identical textures and mineralogy of MIL 11041 and MIL 13079 to these two. Pairing updated in AMN 47,1. |
