- Mirovia – Hypothesized superocean surrounding the supercontinent Rodinia in the Neoproterozoic Era
- Pan-African orogeny – Series of major mountain-forming events in the Neoproterozoic
The Pan-African Ocean is a hypothesized paleo-ocean whose closure created the supercontinent of Pannotia.[1] The ocean may have existed before the break-up of the supercontinent of Rodinia. The ocean closed before the beginning of the Phanerozoic Eon, when the Panthalassa ocean expanded, and was eventually replaced by it.
