Writeup from MB 110:
Northeast Africa 029 (NEA 029) Libya Purchased: 2019 Nov Classification: Carbonaceous chondrite (CVox3) History: Purchased by Mbark Arjdal in November 2019 from a Libyan dealer. Petrography: (A. Irving, UWS and P. Carpenter, WUSL) Relatively large, well-formed chondrules (apparent diameter 1030±580 µm, N = 25; some with multiple rims) and large irregularly-shaped CAI (up to 4 cm across) are set in a fine grained matrix (~30 vol.%, almost opaque sepia brown in thin section) containing troilite, kamacite and magnetite with highly variable Cr2O3 contents. Mineral phases in CAI include gehlenite, Al-Ti-diopside, spinel, taenite and kamacite. Geochemistry: Olivine (Fa15.9±12.7, range Fa2.4-32.1, N = 5), low-Ca pyroxene (Fs7.8±9.6Wo0.9±0.8, range Fs1.0-14.6Wo0.3-1.4, N = 2), subcalcic augite (Fs0.6Wo29.8), Al-Ti diopside (Fs2.4Wo41.1, Al2O3 6.4 wt.%, TiO2 0.8 wt.%), magnetite (Cr2O3 0.1 wt.%, 4.2 wt.%, 7.3 wt.%, N = 3). Classification: Carbonaceous chondrite (CV3, oxidized). Specimens: 20.2 g plus one polished thin section at UWB; remainder with Mr. M. Arjdal. | ||||||||||||||||||||||||||||||
