- •
Rodinia and Pangea represent the two basic types of supercontinent configurations.
- •
True supercontinent cycles involve breakup-assembly of Rodinia-type supercontinents.
- •
The convective pattern in the mantle is the same during each such cycle.
- •
During these cycles, Pangea-type supercontinents are only transient stages.
- •
Rodinia-type supercontinent break-ups coincide with atmospheric oxygenation events.
