NWA 13758 Rumuruti Chondrite - RARE CLASS! 16.3g

NWA 13758 is a rare chondrite that has a lot going for it. The original find was reportedly in the Tanezrouft Plateau, and it has been classified as a Rumuruti (R3) chondrite - a rare class! Below, you’ll find more information on the details of the analysis:

A visible saw cut exposes a breccia with fragment sizes up to approximately 2 cm, set in a fine-grained matrix. Numerous distinct chondrules can be seen throughout. This meteorite contains two main lithologic domains: one with a gray, unstained matrix, and the other with a brownish-orange-stained matrix. Electron microprobe analyses were conducted on each lithologic domain separately. The first domain contains unequilibrated olivine and pyroxene in chondrules and single mineral fragments in the matrix, with small albitic plagioclase grains. Chromite, pentlandite, and troilite are present. No metal or oxidized iron was found. The second domain also contains unequilibrated olivine and pyroxene in chondrules and single mineral fragments in the matrix. It appears to have slightly more chondrules than the first domain. Similarly, very small albitic plagioclase grains are present, along with Ti-rich chromite, pentlandite, and Ni-bearing troilite.

About Stony Meteorites:

Stony meteorites are the most common meteorites, making up the majority of the meteorites discovered here on Earth.  They are divided into two groups: chondrites, which are some of the oldest primitive material in our entire solar system originating from large asteroids, and achondrites, which include meteorites that derived from our moon and Mars.

*Note - Lunar and Martian-originated meteorites will always be indicated as such on the listing. Any other meteorite listed will have originated from an asteroid.
