Writeup from MB 109:

Northwest Africa 7359 (NWA 7359)

Morocco

Purchased: 2019

Classification: HED achondrite (Diogenite)

Physical characteristics: The stone’s surface is 98% covered by a thin fusion crust. Some tan-orange weathering and caliche staining is visible on broken surfaces. Cut surface is orange/tan with scattered areas of dark green.

Petrography: The rock is a monomict and almost completely monominerallic breccia. Surviving pyroxene grain fragments (equant, with optical continuity) are up to 9 mm across. A trace of opaque oxide, probably Cr-spinel, is also present.

Geochemistry: Low-Ca pyroxene compositions (6 analyses) cluster very tightly near Fs24.9Wo3.5, with 1.3 wt% Al2O3, 0.70 wt% Cr2O3, and FeO/MnO (wt) = 30.8.

Classification: Diogenite

Specimens: 22 g at UCLA; main mass (5 kg) with Gessler.
