  2. Rodinia - Wikipedia

    en.wikipedia.org/wiki/Rodinia

    Little is known about the paleogeography before the formation of Rodinia. Paleomagnetic and geologic data are only definite enough to form reconstructions from the breakup of Rodinia [17] onwards. Rodinia is considered to have formed between 1.3 and 1.23 Ga and broke up again before 750 Ma. [18] Rodinia was surrounded by the superocean Mirovia.

    The geology of the Appalachians dates back more than 1.2 billion years to the Mesoproterozoic era [1] when two continental cratons collided to form the supercontinent Rodinia, 500 million years prior to the development of the range during the formation of Pangea. The rocks exposed in today's Appalachian Mountains reveal elongate belts of folded ...

It is preceded by the Mesoproterozoic era and succeeded by the Paleozoic era of the Phanerozoic eon, and is further subdivided into three periods , the ...
