Writeup from MB 106:

Northwest Africa 11219 (NWA 11219)

(Northwest Africa)

Purchased: 2016

Classification: Carbonaceous chondrite (CV3)

History: Two stones totaling 157.6 g were purchased in 2016 by Sergey Vasiliev in St. Marie-aux-Mines from a dealer from Morocco.

Physical characteristics: The two brownish fragments show large chondrules on the cut surface.

Petrography: (A. Bischoff, IfP). Numerous mostly porphyritic chondrules were observed embedded in a fine-grained matrix, which makes up approximately 30-40% of the meteorite. AOAs and fine-grained, spinel-rich CAIs were frequently observed. The chondrules are quite large (~1 mm) typical for CV chondrites.

Geochemistry: (K. Klemm, A. Bischoff, IfP) Mean olivine: Fa8.5 (n=39); mean low-Ca pyroxene: Fs1.5Wo2.1 (n=33); very few Fa-rich olivines occur as fragments in the matrix. Chondrules and AOAs have Fa<9 (Fa4.6±2.3).

Classification: Carbonaceous chondrite (CV3), weathering grade strong (W3)

Specimens: 22.05 g including a polished thin section are at IfP. Sergey Vasiliev holds the main mass.
