NWA 17323 belongs to the CK carbonaceous chondrite group, a rare and oxidized type of meteorite that underwent significant thermal metamorphism on its parent asteroid. CK6 specimens display equilibrated olivine and pyroxene, a dark recrystallized matrix, and trace-element-rich magnetite. These characteristics make them scientifically valuable and highly interesting for collectors, providing insight into the metamorphic history and early formation processes of carbonaceous chondrite parent bodies.

Mineral compositions and geochemistry:
Average olivine composition: Fa32.7 ± 0.4 (Fa32.0–33.3); n = 12; NiO: 0.54 wt%.
Average low-Ca pyroxene composition: Fs27.8 ± 0.5 Wo0.6 ± 0.2 (Fs27.2–28.9 Wo0.4–1.0); n = 10.
Average Ca-rich pyroxene composition: Fs9.4 ± 0.4 Wo46.6 ± 0.5 (Fs8.9–9.8 Wo45.8–47.6); n = 12.
Magnetite shows significant concentrations of elements other than Fe (average, wt%): MgO 0.4; Al₂O₃ 1.8; TiO₂ 0.5; Cr₂O₃ 5.5; NiO 0.3 (n = 5).
