Writeup from MB 107:
El Médano 394 (EM 394) 24°51’S, 70°32’W Antofagasta, Chile Find: 2018 Apr Classification: Enstatite chondrite (EL6) History: The stone was found lying at the surface in the Atacama desert in April 2018. Physical characteristics: A single dark brown stone. Cut face reveals a dark interior with abundant metal. Petrography: (J. Gattacceca, Bertrand Devouard, CEREGE) Highly recrystallized chondritic texture. No visible chondrule in the 1.5 cm2 observed section. Main minerals are enstatite, plagioclase (typical size 100 μm, to 400 μm), kamacite (typical size 300 μm, to mm), sulfides (typical size 150 μm, to 400 μm). No olivine. Sulfides include alabandite, oldhamite, troilite. Geochemistry: Enstatite Fs0.3±0.0Wo1.6±0.0 (N=3). Plagioclase An15.2±0.2Ab80.6±0.7Or4.3±0.5 (N=2). Si in kamacite 1.4±0.0 wt% (N=5). Magnetic susceptibility log χ (× 10-9 m3/kg) = 5.51. Classification: Enstatite chondrite (EL6). EL classification from the Si content of kamacite and the presence of alabandite. Minimal weathering. Specimens: Type specimen 41 g at CEREGE. Main mass with ARTMET. | ||||||||||||||||||||||||||||||||||
