History: Rik Villareal found this meteorite near Anthony Gap, New Mexico, while he was target shooting with his two sons. The meteorite was partially imbedded in the hill slope that they were using as a backstop.
Physical characteristics: Single stone, exterior covered by approximately 75% dark smooth fusion crust. A saw cut reveals abundant, fine-grained metal/sulfide and some larger grains up to 3 mm, a few faint chondrules, fine weathering veins, groundmass reddish brown to black.
Petrography: (C. Agee, UNM) Microprobe examination of a probe mount shows an equilibrated ordinary chondrite texture with a few relict chondrules and relatively coarse plagioclase grains. Approximately 50-70% of the kamacite is oxidized, abundant troilite.
Geochemistry: Mineral compositions: olivine, Fa25.3±0.6; low-Ca pyroxene, Fs21.1±0.6Wo1.5±0.2.
Classification: Ordinary chondrite (L6), weathering grade W2.
Specimens: 31.43 g including a probe mount on deposit at UNM, Rik Villareal holds the main mass.
