Writeup from AMN 31(2):
Sample Number MIL 07003
Newsletter 31,2
Location Miller Range
Field Number 17561
Dimensions 8.0 x 4.5 x 5.0

Original Classification Diogenite
Macroscopic Description - Kathleen McBride
50% of the exterior is covered by dark brown black fusion crust with polygonal fractures. The exposed interior is tan and fractured. The tan interior with yellowish brown patches mars the surface. Black, glassy veins and inclusions and a few white clasts are present.
Thin Section (,4) Description - Tim McCoy and Linda Welzenbach
The section shows a groundmass of coarse (up to 2 mm) comminuted pyroxene with interstitial plagioclase and SiO2. Orthopyroxene has a composition of Fs27-34 Wo1-4 and plagioclase is An85-89Or1 . The Fe/Mn ratio of the pyroxene is ~30. The meteorite is a diogenite, although the pyroxene is on the FeO-rich end of diogenites towards cumulate eucrites.
Oxygen Isotopic Analysis - Z. Sharp, University of New Mexico
Oxygen isotopic analyses of two splits yielded the following results which fall in the HED meteorite field. All samples were cleaned in a 10% HCl solution for 1 minute, followed by ultrasonication.
δ17O=1.57, δ18O= 3.57, Δ17 O = -0.29
δ17O = 1.48, δ18O = 3.66, Δ 17 O = -0.42
[where Δ17O = δ17O - 0.52 x δ18 O]
