Writeup from MB 107:
Northwest Africa 12352 (NWA 12352) Morocco Purchased: 2017 Feb Classification: Ordinary chondrite (H5) Physical characteristics: This sample has a dar-brown fusion crust. The inside shows a dark-gray matrix with a significant number of chondrules and metals. Petrography: (B. Borba de Carvalho, UWO) The thin section exhibits numerous chondrules (up to 1.6 mm) in a dark matrix of medium-grained silicates, metals, minor oxides and sulfides. Most of the chondrules lack well-delineated edges. Major mineral phases are olivine and low-Ca pyroxene. Minor plagioclase and clinopyroxene were observed. No alteration and strong shock features were observed, except for irregular fractures and undulutory extinction in olivine and pyroxene. Fe-Ni metal phases have minor oxide rims. Geochemistry: (EMPA, M. Beauchamp, UWO) Olivine (Fa17.7±0.2; Fe/Mn = 35.6±1.2; n=10), Pyroxene (Fs15.5±0.2 Wo1.4±0.1; Fe/Mn = 20.7±1; n=10), Plagioclase (An13.1±0.5; n=10). Classification: Ordinary chondrite (H5, S2, W1). Specimens: 30.2 g including a thin section at UWO. Main mass with S. Tutorow. | ||||||||||||||||||||||||||||||
