Writeup from MB 110:

Northwest Africa 14350 (NWA 14350)

(Northwest Africa)

Purchased: 2021

Classification: Ordinary chondrite (L4)

History: Purchased from a Moroccan mineral dealer at the mineral show in Bologna, Italy. Purportedly found in Mauritania.

Petrography: (K. Metzler, IfP) Unbrecciated ordinary chondrite, consisting of well-defined chondrules of various textural types with apparent sizes up to ~3 mm. The mean apparent chondrule size is 491 µm (n=72). Accessory phases are Fe-Ni metal and troilite, mostly residing outside of chondrules.

Geochemistry: Mineral compositions and geochemistry: The mean olivine composition is Fa24.3±0.4 (Fa23.6-25.0; n=11) and the mean low-Ca pyroxene composition is Fs18.0±3.8Wo1.2±0.8 (Fs8.6-20.8Wo0.1-3.0; n=31).

Classification: L chondrite based on mean apparent chondrule size and olivine chemistry. Petrologic type 4 based on the equilibrated state of olivine and unequilibrated state of low-Ca pyroxene.
