Writeup from MB 110:
Northwest Africa 14180 (NWA 14180) (Northwest Africa) Purchased: 2021 Jun Classification: Ordinary chondrite (LL6) History: Purchased by Ziyao Wang in June 2021 from a dealer in Ouarzazate, Morocco. Petrography: (A. Irving, UWS and P. Carpenter, WUSL) Highly recrystallized with triple grain junction and poikiloblastic textures (mean grainsize ~70 µm). Three possible but indistinct remnant chondrules were observed in a large area thin section. Composed predominantly of olivine and low-Ca pyroxene with accessory augite, sodic plagioclase, low-Ti chromite, troilite, pentlandite and taenite. Geochemistry: Olivine (Fa31.7±1.1, range Fa31.1-33.3, N = 4), low-Ca pyroxene (Fs25.5±0.2Wo2.0±0.2, range Fs25.2-25.7Wo1.9-2.2, N = 4), augite (Fs10.6±0.2Wo43.6±0.2, range Fs10.3-10.8Wo43.4-43.8, N = 4), plagioclase (Ab83.2An10.7Or6.1). Oxygen isotopes (K. Ziegler, UNM): analyses of acid-washed subsamples by laser fluorination gave, respectively, δ17O 3.899, 4.036, 3.953; δ18O 5.064, 5.402, 5.205; Δ17O 1.226, 1.183, 1.205 (all data linearized). Classification: Ordinary chondrite (LL6). Specimens: 28.9 g including one polished thin section at UWB; remainder with WangZ. | ||||||||||||||||||||||||||||||
