Writeup from MB 112:

Northwest Africa 16123 (NWA 16123)

(Northwest Africa)

Purchased: 2016

Classification: Ordinary chondrite (L6)

History: Purchased in 2016 by Dean Bessey from a mineral dealer in Erfoud, Morocco

Petrography: (K. Metzler, IfP) Equilibrated ordinary chondrite with barely visible chondrules and chondrule fragments. Many secondary feldspar grains with sizes >50 µm. Moderate amounts of Fe-Ni metal, partly oxidized by terrestrial weathering.

Geochemistry: Mineral compositions and geochemistry: Mean olivine composition: Fa25.0±0.5 (Fa24.4-25.9; n=10); mean low-Ca pyroxene composition: Fs20.7±0.2 Wo1.4±0.3 (Fs20.5-21.0Wo1.1-1.8; n=8).

Classification: L chondrite based on mineral chemistry. Petrologic type 6 due to the equilibrated state of olivine and pyroxene and grain size of secondary plagioclase.
