Writeup from MB 111:

Northwest Africa 14452 (NWA 14452)

(Northwest Africa)

Purchased: 2018 Jul

Classification: Carbonaceous chondrite (CK4)

History: Purchased by Ziyao Wang in July 2018 from a dealer in Erfoud, Morocco.

Petrography: (A. Irving, UWS and P. Carpenter, WUSL) Separated equilibrated, magnetite-bearing chondrules and sparse small, very fine-grained, rimmed CAI are set in a fine grained matrix containing orange-stained Cr-magnetite, troilite and pentlandite. Calcite is present in discontinuous veins in some chondrules.

Geochemistry: Olivine (Fa34.4±0.2, range Fa34.2-34.6, N = 5), low-Ca pyroxene (Fs22.0±8.0Wo1.7±1.9, range Fs8.9-27.3Wo0.5-5.1, N = 5), augite (Fs8.4±0.1Wo49.1±0.4, range Fs8.3-8.5Wo48.8-49.4, N = 2), plagioclase (An73.9-76.2Or0.4, N = 2), magnetite (Cr2O3 = 5.5-5.9 wt.%, N = 3).

Classification: Carbonaceous chondrite (CK4).

Specimens: 25.7 g including one polished thin section at UWB; remainder with WangZ.
