Northwest Africa 7935 (NWA 7935)

(Northwest Africa)

Purchased: 2013 April

Classification: Ordinary chondrite (LL5)

History: Purchased by B. Li in Tucson in April 2013.

Physical characteristics: (R. Bartoschewitz, Bart, and B. Li) Meteorite fragment, surface party covered by fusion crust, saw-cut surface shows dark gray clast, chondrules and metal specks, set in a brown-colored matrix. Magnetic susceptibility log χ =3.52.

Petrography: Microprobe examination of a polished thin section shows moderately well developed chondrules (dominantly porphyritic) up to 1.5 mm (mean 0.5 mm), chondrule and mineral fragments in recrystallized matrix with few metal grains.
