Writeup from MB 111:

Northwest Africa 14743 (NWA 14743)

(Northwest Africa)

Purchased: 2021 Dec

Classification: Carbonaceous chondrite (CVox3)

History: Purchased jointly by Craig Zlimen and Mark Lyon in December 2021 from an Algerian dealer.

Physical characteristics: These specimens are noteworthy because of a strong preferred dimensional orientation of elongate, amoeboid to irregularly-shaped CAI.

Petrography: (A. Irving, UWS and P. Carpenter, WUSL) Relatively large, well-formed, mostly spherical chondrules (apparent diameter 2170±670 µm, N = 27) are set in a fine grained matrix (~35 vol.%) containing Cr magnetite, pentlandite and rare taenite. Very fine grained CAI examined by electron microprobe analysis contain hedenbergite, aluminous diopside, and calcite.

Geochemistry: Olivine (Fa7.1±4.9, range Fa0.4-13.4, N = 5), low-Ca pyroxene (Fs0.7±0.1Wo3.3±2.2, range Fs0.6-0.8Wo0.9-5.2, N = 3), diopside (Fs1.2±0.2Wo41.2±1.1, range Fs1.0-1.3Wo42.0-40.4, N = 2), magnetite (Cr2O3 0.3-1.6 wt.%, N = 7).

Classification: Carbonaceous chondrite (CVox3).

Specimens: 46.9 g including one polished mount and one large area polished thin section at UWB; remainder with Mr. C. Zlimen and Mr. M. Lyon.
