Writeup from MB 91:

Northwest Africa 2048

Morocco

Find: 2003

Achondrite (diogenite, monomict)

History: A single stone was found in Morocco and purchased in Rissani, Morocco, in September 2003.

Physical characteristics: The 44.5 g, buff-colored stone is partially fusion-crusted, with moderate desert etching/ weathering.

Petrography: (J. Wittke and T. Bunch, NAU ) Monomict breccia with ~2 mm size orthopyroxene porphyroclasts that are surrounded by recrystallized matrix. Very small (<0.05 mm) olivine, chromite, troilite, plagioclase, and ilmenite grains are scattered throughout the orthopyroxene matrix.

Mineral compositions and geochemistry: Orthopyroxene (Fs25Wo2; FeO/MnO = 34.6, narrow distribution around this value), with minor olivine (Fa28.7; FeO/MnO = 51), plagioclase (An83), and chromite (cr# = 68).

Classification: Achondrite (diogenite, monomict breccia); minimal shock, moderate weathering.

Type specimen: A 9.71 g sample is on deposit at NAU. MFarmer holds the main mass.
