Writeup from MB 99:

Northwest Africa 5363 (NWA 5363)

(Northwest Africa)

Found: unknown

Classification: Ungrouped achondrite

History: Many pieces bought from nomads in February 2008 (Morocco) totaling 2455 g.

Physical characteristics: Many stones partly covered with a slightly weathered dark brown fusion crust. All the pieces were purchased together at one time and collected by the same nomad.

Petrography (A. Jambon, O. Boudouma and D. Badia, UPVI):  Olivine is dominant, with augite, chromite and accessory chlorapatite and iron phosphate. Contains troilite and weathered kamacite. Polygonal granular texture.

Geochemistry: Olivine Fa29 FeO/MnO=65, orthopyroxene En73Fs25Wo2, FeO/MnO = 41, augite En44Fs10Wo45, FeO/MnO = 37, chromite Cr/(Cr+Al =0.81. Oxygen isotopes (J. Gattacceca, C. Suavet, C. Sonzogni, CEREGE): δ17O =2.152‰; δ18O = 4.183‰; Δ17O = -0.023‰.

Classification: Achondrite (ungrouped), appears to be the same type as NWA 5400. Significantly weathered (W2/3).

Specimens: 32 g of sample and one polished section is on deposit at UPVI. Mbark Ait El Caid, Rissani (Morocco) holds the main mass.
