NWA 13366 PERIDOTIC SHERGOTTITE MARTIAN METEORITES

Here we are offering parings of the Martian Peridotitic Shergottite NWA 13366. This is one of the most beautiful Martian meteorites we have see due to its rich olive green hue which is the result of it being composed of approximately 60% olivine!

Excerpt from the Meteorite Bulletin:

Northwest Africa 13366 (NWA 13366)
Algeria
Purchased: 2019
Classification: Martian meteorite (Shergottite) History: Purchased from a nomad in Algeria in 2019 and sent to Dustin Dickens at the Tucson Gem and Mineral Show, February 2020. Physical characteristics: Single stone, saw cut reveals an ultramafic cumulate rock with ophitic to poikilitic textures with mm-size pale yellow and dark gray grains. Petrography: (C. Agee, UNM) Microprobe examination shows approximately 60% olivine, 35% pyroxene, and 5% maskelynite. Two distinct pyroxene trends are present 1) Mg-rich low calcium pyroxene trending to slightly more Fe-rich pigeonite, 2) Mg-rich augite trending to more Ca-rich augite. Ilmenite, Fe-sulfide, and merrillite are minor ubiquitous phases.

Classification: Martian peridotitic shergottite. Macroscopic textural appearance similar to NWA 1950 and ALHA 77005. Paired with NWA 13250.
