Summary
OC parent bodies accreted from a mix of chondrules, chondrule fragments, grains of metallic Fe-Ni and sulfide, porous aggregates of fine-grained dust, and rare CAIs, AOAs, and tiny presolar grains. After accretion, the OC asteroids underwent thermal metamorphism, mainly due to the decay of 26Al. They initially developed onion-shell structures but suffered disruption and reassembly while still hot. Subsequent collisions produced a variety of breccias on each body. The L parent asteroid was destroyed by a catastrophic collision ~470 Ma ago.
