Writeup from MB 110:

Northwest Africa 14349 (NWA 14349)

(Northwest Africa)

Purchased: 2021

Classification: Ordinary chondrite (L3)

Petrography: (K. Metzler, IfP) Shock-darkened ordinary chondrite of low petrologic type consisting of closely packed chondrules (up to ~2 mm), chondrule fragments, Fe-Ni metal grains and troilite, with small amounts of fine-grained interchondrule matrix. The mean apparent chondrule size is 449 µm (n=170).

Geochemistry: Mineral compositions and geochemistry: The mean olivine composition is Fa13.3±9.8 (0.9-35.7; n=24). The mean low-Ca pyroxene composition is Fs7.7±5.6Wo0.8±0.8 (Fs1.0-20.2Wo0.2-2.7; n=12).

Classification: L chondrite, based on metal content and mean apparent chondrule size. Petrologic type 3, based on the chemical variation of olivine and pyroxene.
