Northwest Africa 14215 (NWA 14215)

(Northwest Africa)

Purchased: 2020

Classification: Ordinary chondrite (L5)

Petrography: (K. Metzler, IfP) Unbrecciated ordinary chondrite with recrystallized texture and some porosity, showing moderate amounts of metal and recognizable chondrules of various textural types. Secondary feldspar grains <50 μm.

Geochemistry: Mineral compositions and geochemistry: The mean olivine composition is Fa25.4±0.2 (Fa25.1-25.8; n=11) and the mean low-Ca pyroxene composition is Fs21.1±0.3Wo1.5±0.2 (Fs20.3-21.4Wo1.0-1.7; n=11).

Classification: L chondrite based on mineral chemistry. Petrologic type 5 based on the equilibrated state of olivine and pyroxene, and grain size of secondary plagioclase.
