Writeup from MB 105:

Hassi Bou Talha        28.112°N, 9.890°W

South, Morocco

Find: 2016 Apr 2

Classification: HED achondrite (Eucrite, polymict)

History: Found by a Moroccan prospecting team, 41 km S of Aouinet Lahna, 59 km NWW of Zag and 71 km SW of Assa, Morocco, and subsequently acquired by Fabien Kuntz.

Physical characteristics: A single broken stone (308 g) lacking fusion crust and exhibiting a fine-grained, gray interior.

Petrography: (A. Irving and S. Kuehner, UWS) Breccia composed of sparse lithic clasts (with subophitic to microgabbroic textures) and abundant crystal debris in a finer grained matrix. Minerals are exsolved pigeonite (of several different bulk compositions), calcic plagioclase, silica polymorph, chromite, ilmenite, troilite, rare zircon (as grains up to 30 μm across) and minor secondary calcite.

Geochemistry: Orthopyroxene host A (Fs52.9Wo4.02, FeO/MnO = 28), clinopyroxene exsolution lamella A (Fs18.4Wo44.4, FeO/MnO = 21), low-Ca pyroxene host B (Fs34.2Wo5.8, FeO/MnO = 29), clinopyroxene exsolution lamella B (Fs14.1Wo41.5, FeO/MnO = 21).

Classification: Eucrite (polymict breccia).

Specimens: 20.55 g including one polished thin section at PSF; remainder with Kuntz.
