Writeup from MB 101:

Northwest Africa 7369 (NWA 7369)        ~22°12’N, ~13°09’W

Western Sahara

Found: 2007

Classification: Rumuruti chondrite (R5)

History: Discovered by an anonymous finder near Aghoninit, Western Sahara

Physical characteristics: One complete individual of 650 g covered with fresh black fusion crust.

Petrography: (R. Bartoschewitz, Bart) Chondrules (0.3-0.6 mm), larger chondrule fragments (<2 mm), olivine and pyroxene fragments (<0.3 mm) set in a recrystallized matrix. Chromite (<0.2 mm) is distributed throughout the matrix and also inside some chondrules. Feldspar is mostly transformed to maskelynite and dominantly forms assemblages with chromite. Accessory minerals are pentlandite and troilite.

Geochemistry: (R. Bartoschewitz, Bart; P. Appel, B. Mader, Kiel) Olivine Fa38.4-39.6 (n=26); clinopyroxene Fs11.3-16.0Wo40.0-46.1 (n=15). Chromite Al2O3 = 4, TiO2 = 5, MgO = 1; pentlandite Ni = 33, Co = 1; troilite Ni = 2.5, Co = 0.2 (all in wt%).

Classification: Rumuruti chondrite (R5), W0
