Writeup from MB 111:

Northwest Africa 14680 (NWA 14680)

(Northwest Africa)

Purchased: 2021 Nov

Classification: Ordinary chondrite (LL3)

Petrography: (K. Metzler, IfP) Unequilibrated ordinary chondrite, consisting of closely packed chondrules and chondrule fragments, with low amounts of interchondrule matrix. The mean apparent chondrule size is 580 μm (n=160). Small amounts of Fe-Ni metal (partly terrestrially oxidized) and troilite, mostly residing outside of chondrules.

Geochemistry: Mineral compositions and geochemistry: The mean olivine composition is Fa14.7±11.0 (Fa1.0-42.6; n=24); the mean low-Ca pyroxene composition is Fs8.7±6.6Wo1.0±0.8 (Fs1.5-20.9Wo0.3-2.5; n=18).

Classification: LL chondrite, based on the low metal content and large mean apparent chondrule size. Petrologic type 3, based on the chemical variation of olivine and pyroxene. Petrologic subtype <3.5, based on the high PMD of Fa values (PMD=75).

Specimens: The largest stone has a weight of 1194 g.
