Writeup from MB 111:
Northwest Africa 14982 (NWA 14982) Morocco Find: 2019 Classification: Carbonaceous chondrite (CV3) History: The stone was recovered in Morocco during the summer of 2019. It was sold to a Chinese meteorite collector Zhang Bo at the Munich mineral show in Oct. 2019. In September 2020, Shanghai Planetarium purchased a 8.5 kg end cut of the stone. Zhang Bo holds the main mass (16.5 kg). Physical characteristics: A single black stone in the size of 40 × 18 × 115 cm. Fusion crust is well preserved. Several large (cm-sized) round CAIs are visible on the surface and on the slices. Petrography: The stone contains abundant relatively large, well-shaped chondrules (~0.2-5 mm, ~45 vol%). Several irregularly shaped CAIs (5 vol%) are embedded in a fine-grained silicate and opaque matrix (50 vol%). The major silicate minerals include olivine, low calcium pyroxene and plagioclase. The mineral phases in CAIs include gehlenite, spinel, perovskite and fassaite. Geochemistry: Mean olivine: Fa6.1 (range Fa0.3-15.2); mean low-Ca pyroxene: Fs1.2Wo0.9 (range Fs0.7-2.4Wo0.7-1.0) | ||||||||||||||||||||||||||||
