Classification: Chondrite LL(L)5 S2 / W1
Place/Time: 2021 in Morocco
History: The meteorite was purchased from a dealer in Morocco.
Physical characteristics: Grayish rock partly covered with fusion crust.
Petrography: The meteorite shows a light grayish interior and is a brecciated ordinary chondrite with large, still mostly discernable chondrules (apparent mean diameter about 1 mm). The plagioclase grain size is about 60 µm. Some metal and sulfides are present in the matrix. Contains shock melt veins.
Geochemistry: The composition of olivine Fa26.3±0.1 (n=4) and orthopyroxene Fs21.9±0.1 (n=4)Wo1.7±0.1 (n=4) are at the limit between that of L and LL groups.
Classification: Ordinary chondrite LL(L)5. LL group is favored based on magnetic susceptibility, but the mineral composition is somewhat intermediate between L and LL groups, hence the LL(L) classification.
This is the only approved meteorite classified as LL(L)5! After cut and polish 1720g left and only 850g is in slices.
All slices both side polished, 3.3mm thin
