Northwest Africa 13050 (NWA 13050)

(Northwest Africa)

Purchased: 2019

Classification: Ordinary chondrite (L6, melt breccia)

History: In May 2019 at the mineral show in Chenzhou Ziyao Wang discovered on the bottom of a box with ordinary chondrites from Northwest Africa some small strange stones and donated some material to Rainer Bartoschewitz. Some of these stones are of meteoritic and others of terrestrial origin.

Physical characteristics: 92.3 g dark gray-brown irregular angular stone with many cracks

Petrography: (R. Bartoschewitz, Bart) subrounded chondritic clasts and mineral fragments with very thin metallic rims set in a black matrix with finely dispersed metal grains <5 µm.

Geochemistry: (R. Bartoschewitz, Bart, P. Appel and B. Mader, Kiel) Olivine Fa24.2±0.2 (n=12); feldspar An11-17Or5-3 (n=2); chromite CRAL=86 FFM=81-83 (n=2). Magnetic susceptibility (R. Bartoschewitz, Bart) log χ (× 10-9 m3/kg) = 4.62

Classification: Ordinary chondrite (L6 melt breccia)

Specimens: 16.4 g on deposit in Kiel, 64 g and polished thin section with Bart
