Northwest Africa 14425 (NWA 14425)
(Northwest Africa)
Purchased: 2021 Feb
Classification: Enstatite chondrite (EH3)
History: Purchased by Jason Whitcomb in February 2021 from an Algerian dealer.
Petrography: (A. Irving, UWS and J. Boesenberg, BrownU) Mostly relatively small enstatite-forsterite-bearing chondrules (exhibiting a wide size variation, apparent diameter 380±410 µm, N = 24) are set in a fine grained matrix containing daubreelite, troilite, altered Si-bearing kamacite, perryite, schreibersite, oldhamite and albitic glass. Several chondrules contain relatively ferroan low-Ca pyroxene.
Geochemistry: Enstatite (Fs1.3±0.9Wo0.4±0.3, range Fs0.3-4.1Wo0.0-1.0, N = 19), forsterite (Fa0.3±0.1, range Fa0.3-0.4, N = 3), relatively ferroan low-Ca pyroxene (Fs13.4±3.8Wo3.0±1.1, range Fs11.4-19.1Wo4.2-1.9, N = 4).
Classification: Enstatite chondrite (EH3). The presence of relatively ferroan low-Ca pyroxene in addition to the dominant enstatite has been previously documented in EH3 chondrite Yamato 691.
Specimens: 24.83 g including one polished thin section at PSF; remainder with Mr. J. Whitcomb.

Chwichiya 002 is an ordinary carbonaceous chondrite of type C3.00 ungrouped, it is the most primitive type that has ever been found in this date, it has not undergone any hydrated phase and no heating before its expulsion from the parent body.
This meteorite is perhaps one of the most important meteorites of all times, no doubt that the knowledge of our solar system will advance thanks to it.
It was discovered in the Western Sahara. A must for a collection!
