DescriptionIn this research, an impact between the protoplanet Pallas, which hosts a large crater and has a surface composition very similar to the CR carbonaceous chondrites and an iron-nickel impactor, is suggested to be the formation mechanism for the CBb chondrules. The CBb chondrules may have formed by melting, evaporation and condensation, possibly in the vapor cloud generated by the impact between Pallas and the iron-nickel impactor. Through experimental petrology, the skeletal olivine (SO) texture of the CBb chondrules has been replicated using cooling-reheating cycles. By combining my new cooling-reheating temperature data for the formation of the CBb chondrules with previous research a unified impact model has been developed for the CBb chondrites and their genetically related partners, CBa, CH, and CR. .
