Writeup from MB 104:

Northwest Africa 10063 (NWA 10063)

(Northwest Africa)

Purchased: 2014

Classification: Ordinary chondrite (L3)

History: Purchased from Morocco, 2014.

Physical characteristics: Three identical appearing pieces with weathered exterior. A saw cut reveals many densely packed chondrules of variable size set in a dark reddish ground mass.

Petrography: (C. Agee, UNM) Microprobe examination of a polished mount shows numerous unequilibrated chondrules, apparent mean diameter 530±320 μm (n=58), many with porphyritic, igneously zoned olivines and pyroxenes. Some scattered, opaque, fine-grained matrix is present.

Geochemistry: (C. Agee and N. Muttik, UNM) Chondrule olivine Fa24.6±7.3, range Fa1.7-31.6, Fe/Mn=70±49, Cr2O3=0.05±0.04 wt%, n=44, chondrule low-Ca pyroxene Fs11.5±6.5Wo0.9±1.1, Fe/Mn=28±16, n=21.

Classification: Ordinary chondrite L3, estimated type 3.4-3.6 based on mean values and 1-sigma of Fa and Cr2O3-content of ferroan olivines.

Specimens: 23.6 g including a probe mount on deposit at UNM, Steve Arnold holds the main mass.
