Achondrite (eucrite, polymict)

History: A single stone of 504.7 g partly covered with fusion crust was found in 2005 in the western part of the Sahara in Morocco.

Petrography: (A. Greshake, MNB) A polymict breccia dominated by large basaltic clasts set into a fine-grained groundmass with rare melt clasts and large mineral fragments, the latter being mostly plagioclase and exsolved Ca pyroxene. Minor phases include silica and ilmenite.

Geochemistry: Plagioclase (An74.1–90.7), pyroxene (Fs41.6–65.4Wo2.9–29.3).

Classification: Achondrite (eucrite, polymict); low shock, minimal weathering.

Specimens: A 22 g type specimen and one polished thin section are on deposit at MNB. HSSH-Pirmasens of Germany holds the main mass.
