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 | ||||||||||||||||||||||||||||||||||
