Achondrite (eucrite)

History: John Birdsell and Marvin Killgore purchased a 1600 g stone.

Petrography: (D. Hill and K. Gardner, UAz) The stone was 100% covered with black fusion crust. There are a variety of light and dark angular clasts ranging in size from several mm to ~2 cm and rounded grains several millimeters in diameter. They are set in a light matrix typical of eucrites except for its distinct pink hue. Some systematic variations in the color exist. Approximately half of the slice is slightly darker pink than the other with an indistinct, irregular boundary.

Geochemistry: Pyroxene (Wo6En36Fs59 and Wo40En30Fs30), plagioclase (An90Ab10Or0.4), chromite (TiO2 = 5–27, Al2O3 = 5 [both wt%]), with minor ilmenite present. Bulk INAA (UAz) indicate ~1 0× CI REE abundances.

Classification: Achondrite (eucrite); minimal weathering.

Specimens: One thick section type specimen of 20.5 g and three small chips totaling 2.5 g are on deposit at UAz. M. Killgore holds the main mass.
