Writeup from MB 104:
Northwest Africa 10036 (NWA 10036) Morocco Purchased: 2014 Classification: Enstatite chondrite (EL5) History: Purchased by Nicola Castellano at the Genova Mineral Fair in May 2014 from a Moroccan dealer. Physical characteristics: A single piece weighing 145 g totallycovered by fusion crust. Petrography: (V. Moggi Cecchi, G. Pratesi, S. Caporali, UniFi); The thin section shows a partially equilibrated texture, with a matrix, mainly represented by pyroxene and minor plagioclase, and scattered chondrules, easily distinguishable from the matrix. Chondrules are mainly RP type, with minor GP, and range from 0.3 to 0.9 mm in diameter. Opaque phases, mainly consisting of kamacite and troilite, are weathered to iron oxides. Accessory alabandite and daubreelite blades in troilite are visible. The presence of alabandite, An content of plagioclase and Si content of kamacite point to a classification as EL chondrite; chondrules suggest petrologic type 5. Geochemistry: Orthopyroxene (Fs0.4En98.3Wo1.2), plagioclase (An16.3Or5.5); Si in kamacite = 0.9 wt.%, Ti in troilite = 6.4 wt.% Classification: Enstatite chondrite (EL5) Specimens: A total of 21.8 g specimen and one thin section is on deposit at MSN-FI. Castellano holds the main mass. | ||||||||||||||||||||||||||||||
