Writeup from MB 111:
Northwest Africa 14559 (NWA 14559) (Northwest Africa) Purchased: 2021 Classification: Carbonaceous chondrite (CK3) History: Puchased by Nicholas Gessler in 2021 from a Moroccan dealer. Petrography: (A. Irving, UWS and J. Boesenberg, BrownU) Discrete well-formed unequilibrated chondrules, distinct Type 3 lithic chondrite clasts, and rare fine-grained AOA are set in a fine-grained matrix (~50 vol.%) containing Cr-magnetite (extensively altered to deep red-brown hydroxides), chlorapatite, and minor pentlandite. The studied thin section also contains a fine grained lithic clast (mean grainsize ~100 µm) with protogranular texture composed mainly of compositionally-zoned olivine and unzoned augite together with labradoritic plagioclase and accessory Cr-magnetite. Geochemistry: Olivine in discrete chondrules and Type 3 lithic clasts (Fa27.8±7.0, range Fa19.7-37.4, N = 8), low-Ca pyroxene (Fs4.1Wo0.8), subcalcic augite (Fs17.9Wo22.2), augite (Fs13.3Wo48.3), plagioclase (An26.8-39.3Or3.3-1.7, N = 3), magnetite (Cr2O3 2.7-6.6 wt.%, N = 11). Protogranular clast: olivine (Fa31.6±10.2, range Fa6.5-37.8, N = 9), augite (Fs14.4±0.3Wo47.9±0.1, range Fs14.2-14.8Wo48.0-47.8, N = 3), plagioclase (An54.2Or2.1). Classification: Carbonaceous chondrite (CK3). Specimens: 22.5 g plus one polished thin section at UWB; remainder with Mr. N. Gessler. | ||||||||||||||||||||||||||||||
