Writeup from MB 105:

Northwest Africa 11039 (NWA 11039)

(Northwest Africa)

Purchased: 2014

Classification: Ordinary chondrite (L4)

History: One stone of 28.8 g was purchased in 2014 by Sergey Vasiliev in Morocco.

Physical characteristics: The cut surface shows well-defined chondrules and a low matrix abundance.

Petrography: (A. Bischoff, S. Ebert, IfP). In the polished thin section, numerous mostly porphyritic chondrules were observed embedded in a fine-grained matrix of low abundance, typical of ordinary chondrites. The chondrules are 0.5 mm in apparent diameter, typical for the L-group.

Geochemistry: Mineral compositions and geochemistry: (K. Klemm, A. Bischoff, IfP) olivine Fa24.8±0.7 (n=18); low-Ca pyroxene Fs17.6±5.4Wo0.5±0.3 (n=19).

Specimens: 8.06 g including a polished thin section are at the IfP. Sergey Vasiliev holds the main mass.
