Writeup from MB 111:

Northwest Africa 14662 (NWA 14662)

(Northwest Africa)

Purchased: 2015

Classification: Ureilite

History: Purchased by Ziyao Wang in 2015 from a Moroccan dealer at the Hunan Mineral and Gem Show in Chenzhou City, China.

Physical characteristics: Extremely hard specimen evidently containing a significant amount of diamond (confirmed by electron microprobe analysis).

Petrography: (A. Irving, UWS and P. Carpenter, WUSL) Protogranular aggegate (mean grainsize ~0.6 mm) composed of olivine (~60 vol.%) and pigeonite (~40 vol.%) together with accessory diamond (cathodoluminescent yellow), graphite, V-bearing daubreelite and kamacite. Olivine grains have magnesian reduced rims associated with fine blebby Fe metal.

Geochemistry: Olivine (cores Fa14.5-14.9, CaO = 0.26-0.30 wt.%, Cr2O3 = 0.50-0.54 wt.%, N = 4; rims Fa1.6-2.1, N = 5), pigeonite (Fs12.3-13.3Wo4.6-9.2, Al2O3 = 1.6-2.9 wt.%, Cr2O3 = 0.95-1.08 wt.%, TiO2 = 0.16-0.20 wt.%, N = 4).

Classification: Ureilite (diamond-rich).

Specimens: 21.2 g including one polished thick section at UWB; remainder with WangZ.
