Abstract

Aggregates consisting largely of submicrometre graphite and magnetite crystals have been identified in 14 unequilibrated and regolith breccia, ordinary chondrites. Like other primitive components, they formed before the meteorites accreted. Chondrite clasts rich in graphite–magnetite occur in three regolith breccias and are a new kind of unequilibrated ordinary chondrite. They were probably the source of graphite–magnetite aggregates in regolith breccias.
