Writeup from MB 110:

Northwest Africa 14161 (NWA 14161)

Algeria

Purchased: 2021

Classification: Carbonaceous chondrite (CV3)

Petrography: (J. Gattacceca, CEREGE) Mm-sized chondrules and CAIs set in a an abundant fine-grained, iron-rich matrix. Terrestrial weathering is high. Opaque minerals are magnetite, rare metal enclosed in silicates, and terrestrial weathering products. No sulfide has survived weathering.

Geochemistry: Olivine Fs4.0±2.8, range Fa0.9-9.5 (n=9). Low-Ca pyroxene Fs2.1Wo3.8 (n=2). Ca-pyroxene Fs1.8Wo52.1 (n=2). Cr2O3 in magnetite 1.3 wt% (n=2).

Classification: Carbonaceous chondrite (CV3). Terrestrial weathering, with associated complete disappearance of sulfides, makes it difficult to decide between CVred and CVox.
