Writeup from MB 110:

Northwest Africa 14013 (NWA 14013)

(Northwest Africa)

Purchased: 2015 Jun

Classification: Rumuruti chondrite (R3-4)

History: Purchased by Ziyao Wang in June 2015 from a Moroccan dealer at the Hunan Mineral and Gem Show in Chenzhou City, China.

Petrography: (A. Irving, UWS and P. Carpenter, WUSL) Very fresh specimen with no evidence of weathering effects. Breccia composed of discrete unequilibrated chondrules (apparent diameter 570 ± 330 µm, N = 25) plus Type 3 and Type 4 lithic clasts set in a fine grained matrix containing pentlandite, troilite, pyrrhotite, low-Ti chromite and sodic to intermediate plagioclase. A tiny OsFe alloy inclusion was found in one troilite grain.

Geochemistry: Olivine in unequilibrated chondrules and Type 3 clasts (Fa26.7±16.9, range Fa4.8-39.7, N = 5), olivine in equilibrated Type 4 clasts (Fa39.3±0.2, range Fa39.1-39.4, N = 2), low-Ca pyroxene (21.4±9.7Wo1.1±0.9, range Fs7.5-29.8Wo0.3-2.2, N = 4), augite (10.5±0.8Wo46.3±0.6, range Fs9.9-11.0Wo45.8-46.7, N = 2).

Classification: R3-4 chondrite breccia. This specimen is notable for its freshness and the presence of a rare accessory Os-rich alloy phase.

Specimens: 5.3 g including one polished thin section at UWB; remainder with Mr. Z. Wang.
