Writeup from MB 109:

Northwest Africa 13127 (NWA 13127)

Morocco

Purchased: 2012

Classification: Ordinary chondrite (LL6)

History: Purchased from Said Hadnany who acquired it from Morocco. Sample is catalogued at ROM as LM58143.

Petrography: Chondrules are very poorly defined. Extensive recrystallization of matrix and coarse grain sizes indicate high levels of thermal metamorphism. Irregular, and planar of fractures of olivine indicate a weakly shocked sample, undulose extinction is evident in certain grains. This sample has been moderately weathered with about 20-30% of metal/sulfides being replaced. Large conglomerates of sulfides and metal occur together.
