Northwest Africa 16415 (NWA 16415)
Purchased: 2023 Sep
Classification: Carbonaceous chondrite (CO3)
Petrography: (K. Metzler, IfP) Chondrules, chondrule fragments, and CAIs are embedded in a fine-grained dark brown matrix (about 25 vol% matrix). The vast majority of chondrules belong to chemical type I. Chondrule sizes mostly between 50 and 300 µm.
Geochemistry: Mineral compositions and geochemistry: Olivine composition: Fa7.3±5.2 (Fa0.4-22.5); n=16. Composition of low-Ca pyroxene: Fs2.4±1.6Wo1.8±1.2 (Fs0.8-5.3Wo0.6-4.5); n=18.
Classification: CO chondrite based on CAI occurrence, small chondrule size, chondrule-matrix ratio, and mineral chemistry. Petrologic type 3 based on the chemical variation of olivine and pyroxene. Petrologic subtype () based on the PMD of Fa values (~71).
Shock stage: C-S1
Weathering grade: high
Classifier: K. Metzler, IfP.
