Physical characteristics: A single dark stone partially covered with fusion crust. Chondrules and CAIs are visible on the cut surface. Petrography: Chondrules (mostly type I) and CAIs set in a fine-grained Fe-rich foliated matrix. Matrix:chondrule ratio (by point counting, N=298) is 41:59. Average chondrule apparent size 750±410 μm (N=35). Sulfide/magnetite assemblages are abundant in the matrix as μm-sized grains, and around and inside chondrules as blebs up to 100 μm. No metal was observed. Geochemistry: Olivine Fa2.7±2.3 (Fa0.6-9.0, median Fa2.3, N=21), orthopyroxene Fs1.3±0.2Wo1.5±0.9 (N=5). Magnetite contains 1.6 wt% Cr2O3. Magnetic susceptibility log χ = 4.30 (χ in 10-9 m3/kg). Classification: CV3, oxidized subgroup. Specimens: 7 g at CEREGE. Main mass with P. Thomas. | ||||||||||||||||||||||||||||||
