• ProterozoicCompared with: Its older rocks provide the direct geological baseline for the Proterozoic.

• Nuvvuagittuq Greenstone BeltNarrower topic: The belt is classified as Archean, though its oldest proposed ages reach earlier.

• Dresser FormationNarrower topic: The formation’s age places it in the Archean, near the beginning of the preserved rock record.

• Fennoscandian ShieldBroader topic: Parts of the shield contain crust dating to this early chapter of Earth history.

• Sudbury BasinNarrower topic: The impact occurred near the end of the Archean, placing Sudbury among Earth’s oldest major impact structures.
