Northwest Africa 14880 (NWA 14880)

(Northwest Africa)

Purchased: 2021 Sep

Classification: Carbonaceous chondrite (CV3)

History: Purchased by Jason Whitcomb in September 2021 from an Algerian dealer.

Petrography: (A. Irving, UWS and J. Boesenberg, BrownU) Well-formed, glass-bearing chondrules (some with multiple concentric rims, apparent diameter 1090±590 µm, N = 25) and irregularly-shaped, fine-grained CAI are set in a fine-grained matrix (~40 vol.%, deep red-brown in thin section) containing magnetite and kamacite. Several CAI are composed of gehlenite, diopside, olivine, anorthite, and spinel.

Geochemistry: Olivine (Fa8.8±12.2, range Fa0.3-34.3, N = 12), low-Ca pyroxene (Fs1.3±0.3Wo1.0±0.5, range Fs1.0-1.5Wo0.7-1.6, N = 3), pigeonite (Fs0.8Wo8.9), augite (Fs1.1±0.5Wo40.1±4.2, range Fs0.5-1.9Wo36.9-47.2, N = 5), and magnetite (Cr2O3 1.7-2.1 wt.%, N = 6).

Classification: Carbonaceous chondrite (CV3).

Specimens: 21.0 g including one polished thin section at PSF; remainder with Mr. J. Whitcomb.
