Macroscopic Description - Kathleen McBride
The rough exterior is covered with rusty fusion crust. The interior is rusty black with some tiny inclusions.
Thin Section (,2) Description - Cari Corrigan, Tim McCoy and Linda Welzenbach
The section consists of an equigranular aggregate of olivine, pyroxene, plagioclase, and metal with minor sulfide and chromite, with an average grain size of 0.5 mm. Olivine (Fa12) and pyroxene (Fs4-11) are homogeneous. Six calcic pyroxene grains were analyzed (Fs4). Feldspars are also homogeneous (An12Or4). The meteorite is probably a transitional acapulcoite-lodranite similar to, e.g., GRA 95209. This is most likely paired with MIL 07409.
