Writeup from MB 110:

Northwest Africa 14069 (NWA 14069)

(Northwest Africa)

Purchased: 2020 Mar

Classification: Carbonaceous chondrite (CVox3)

History: Purchased by Eric Twelker in March 2020 from a Moroccan dealer.

Petrography: (A. Irving, UWS and P. Carpenter, WUSL) Well-formed magnetite-bearing chondrules (apparent diameter 800±360 µm, N = 24) plus very fine grained, amoeboid CAI are set in a fine grained matrix (~40 vol.%, sepia-brown to opaque in thin section) containing accessory Cr-bearing magnetite and calcic plagioclase. No sulfides were found. One CAI is composed of gehlenite, perovskite, spinel and pleonaste, and contains a tiny Ir metal nugget.

Geochemistry: Olivine (Fa11.8±10.3, range Fa0.3-27.5, N = 5), low-Ca pyroxene (Fs3.0±1.2Wo2.1±2.1, range Fs1.6-3.7Wo0.9-4.5, N = 3), subcalcic augite (Fs0.6Wo32.8), augite (Fs1.4Wo38.2; Fs49.5Wo49.4; N = 2), plagioclase (An80.2Or0.0; An90.1Or0.1; N = 2), magnetite (Cr2O3 = 0.1-1.1 wt.%, N = 3).

Classification: Carbonaceous chondrite (CV3, oxidized).

Specimens: 21.5 g including one polished thin section at UWB; remainder with Mr. E. Twelker.
