Writeup

Writeup from MB 104:

Northwest Africa 10059 (NWA 10059)

Morocco

Purchased: 2014

Classification: Ordinary chondrite (H3)

History: Purchased in 2014 in Erfoud Morocco by Brahim Tahiri from a meteorite hunter and sent to his partner Sean Tutorow for classification.

Petrography:

Classification: The olivine has a composition of Fa_17.6±1.4(n=20) with a PMD of 5%, consistent with subtype 3.9 (according to the Huss et al. (2006) table). The low-Ca pyroxene has a composition of Fs_11.0±5.6(n=19) with a PMD of 42.0%, consistent with subtype =<3.6. The rock also contains some recrystallized matrix material, recognizable in spots even through the severe weathering. Recrystallized matrix is generally absent in type 4 chondrites.
