Writeup from MB 106:

Northwest Africa 10752 (NWA 10752)

(Northwest Africa)

Purchased: 2015 Feb

Classification: HED achondrite (Diogenite)

History: Purchased by Dr. David Gregory in February 2015 from a Moroccan dealer at the Tucson Gem and Mineral Show.

Petrography: (A. Irving and S. Kuehner, UWS) Coarse grained aggregate of predominantly orthopyroxene (exhibiting undulose extinction and recrystallized cataclastic zones) with accessory olivine and chromite.

Geochemistry: Orthopyroxene (Fs23.3-23.7Wo1.4-1.5, FeO/MnO = 23-25, N = 3), olivine (Fa27.8-27.9, FeO/MnO = 41-42, N = 3). Oxygen isotopes (K. Ziegler, UNM): analysis of acid-washed subsamples by laser fluorination gave, respectively, δ17O 1.361, 1.279, 1.540; δ18O 3.159, 3.006, 3.449; Δ17O -0.307, -0.308, -0.281 per mil.

Classification: Diogenite.

Specimens: 14 g plus one polished thin section at ROM; remainder with DGregory.
