Northwest Africa 7347 (NWA 7347)

Morocco

Purchased: 27 January 2012

Classification: Ordinary chondrite (L6, melt breccia)

History: An unusual looking stone was bought at the Tucson Gem and Mineral Show, and later confirmed to be a meteorite.

Physical characteristics: The stone is brown with a bumpy surface, remnant fusion crust, and caliche. The cut surface is dark gray, showing areas of melt and chondritic material.

Petrography: (A. Rubin, UCLA) Interior shows area of melt containing mafic grains, chondrule fragments, and 30-µm-size metal-sulfide assemblages. The unmelted portion shows equilibrated textures, and contains numerous thin sulfide veins, 50-μm-size plagioclase grains, and olivine with strong mosaic extinction.
