229.86g CO3 - Carbonaceous Chondrite Meteorite
On Offer: 229.86g CO3 Carbonaceous Chondrite Meteorite
Type: CO3 Carbonaceous Chondrite
Name: NWA 14489
Description: An amazing new CO3 carbonaceous chondrite with very low weathering. This new CO3 meteorite is a beautifully shaped complete individual with low equilibration. Slices of this meteorite reveal gorgeous tightly packed well formed chondrules set against a barely visible matrix and sprinkled liberally with cosmologically ancient refractory inclusions (CAIs) that scientists use to determine the age of the Solar System because its the oldest known material that we have ever found.
What you get: CO3 Carbonaceous Chondrite specimen as shown, and signed Certificate of Authenticity.
I offer a 100% no questions asked 30 day return policy.

Writeup from MB 110:
Northwest Africa 14489 (NWA 14489)
Purchased: 2021 Jun
Classification: Carbonaceous chondrite (CO3)
History: Purchased by Craig Zlimen in June 2021 from an Algerian dealer.
Petrography: (A. Irving, UWS and P. Carpenter, WUSL) Small well-formed chondrules (apparent diameter 180±80 µm, N = 24), angular olivine grains and very fine grained CAI are set in a fine grained matrix (~40 vol. %, deep reddish-brown in thin section) containing troilite, kamacite, plagioclase and taenite. Minerals in CAI include Al-Ti-diopside, gehlenite, V-bearing spinel, perovskite, hibonite and ilmenite (associated with perovskite).
Geochemistry: Olivine (Fa32.7±24.8, range Fa0.9-64.1, N = 5; Cr2O3 in ferroan olivine 0.06-0.21 wt.%, mean 0.14±0.06 wt%, N = 6), matrix olivine (Fa83.0), low-Ca pyroxene (Fs2.7±1.0Wo2.0±2.4, range Fs1.6-3.5Wo0.6-4.8, N = 3), pigeonite (Fs25.7Wo6.7), subcalcic augite (Fs19.1Wo36.0), Al-Ti-diopside (Fs2.8Wo40.1, Al2O3 8.3 wt.%, TiO2 1.2 wt.%), plagioclase (An40.1Or0.0; An82.7Or0.0; N = 2).
Classification: Carbonaceous chondrite (CO3).
Specimens: 29.2 g including one polished thin section at UWB; remainder with Mr. C. Zlimen.
