Morocco

Purchased: 2014 Feb

Classification: Ordinary chondrite (H6)

History: Purchased from a Moroccan dealer in 2014

Physical characteristics: Physical Characteristics: Covered with black fusion crust. Saw cut reveals abundant metal and sulfides.

Petrography: (AS Djakaria and IJ Ong, UAz) Microprobe examination of a polished mount shows chondrules of 500-1500 μm. Plagioclase grains 100-200 μm observed. Large, moderately oxidized, kamacite and taenite grains are common and are connected by a widespread set of complex, convoluted, small metal veins incorporating numerous small silicate inclusions. Troilite, chromite, merrillite, and chlorapatite are also present.

Geochemistry: Mineral compositions and geochemistry: (AS Djakaria and IJ Ong, UAz) Olivine Fa18.9±0.2, Fe/Mn=36.9±1.7, n=10; low-Ca pyroxene Fs16.8±0.4Wo1.7±0.1, Fe/Mn=22.9±1.5, n=10; Kamacite Fe=91.51±0.82, Ni=6.93±0.21, Co=0.51±0.03, n=3.

Classification: Ordinary Chondrite (H6), Weathering grade W2.
