Writeup from MB 104:

Northwest Africa 10265 (NWA 10265)

(Northwest Africa)

Purchased: 2015

Classification: Primitive achondrite (Lodranite)

History: Seven identical stones were purchased by Adam Aaronson in Temara, Morocco over the period May to August 2015.

Physical characteristics: No fusion crust is evident. The interior of each stone consists of large grains of distinctly green pyroxene and yellow-brown olivine with subordinate stained metal.

Petrography: (A. Irving and S. Kuehner, UWS) Coarse grained (up to 6.5 mm) protogranular aggregate of predominantly clinopyroxene (finely exsolved) and olivine with accessory chromite (red-brown in thin section), Ni-poor kamacite and troilite.

Geochemistry: Olivine (Fa11.0-11.2, FeO/MnO = 33-36, N = 4), clinopyroxene host (Fs4.1-4.6Wo42.7-44.0, FeO/MnO = 12, Cr2O3 = 1.1-1.3 wt.%, N = 4), orthopyroxene exsolution lamellae (Fs9.7-10.6Wo0.9-2.3, FeO/MnO = 18-24, N = 4).

Classification: Lodranite (wehrlitic).

Specimens: 20.1 g including one polished thin section at UWB; main masses with Aaronson.
