Writeup from MB 107:
Caleta el Cobre 024 ~24°20’S, ~70°15’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. One relict chondrule observed in the 2 cm2 studied section. Main minerals are enstatite, plagioclase (typical size 100 μm, to 200 μm), kamacite (typical size 100 μm), sulfides (typical size 100 μm, also present as abundant 5-10 μm mixed sulfides/kamacite grains in the silicates). No olivine. Sulfides include alabandite and troilite. Geochemistry: Enstatite Fs0.4±0.1Wo1.4±0.0 (N=3). Plagioclase An14.4±0.5Ab81.2±0.5Or3.8±0.0 (N=2). Si in kamacite 1.5±0.1 wt% (N=5). Magnetic susceptibility log χ (× 10-9 m3/kg) = 5.36. Classification: Enstatite chondrite (EL6). EL classification from the Si content of kamacite and the presence of alabandite. Minimal weathering. This meteorite was found 2 km away from the Caleta el Cobre 025 EH3 meteorite. Specimens: Type specimen 32 g at CEREGE. Main mass with ARTMET. | ||||||||||||||||||||||||||||||||||
