Rodinia Button for link to Chinese version of this page
Rodinia was a continent that existed from about 1.2 billion years ago until about 750 million years ago. It is one of several supercontinents that are supposed to have formed and then broken up over the past hundreds of millions of years. There may have been earlier supercontinents. The breaking apart of Rodinia involved lots of activity in the crust such as the Grenville Orogeny, leaving us today with much of the world’s older igneous rocks. Pangea is a supercontintent that formed and broke up millions of years after Rodinia.

Links about the Rodinia:
  1. A page about the geological history of Jamestown, Rhode Island has a section about Rodinia that shows a map by Peter R. Johnson (1998) of how the continent may have looked.
  2. As is usual for very ancient time scales, the Paleos website has a great page about Rodinia.
  3. There is a fine page by “Chris” at the Peripatus site about Rodinia with some good references and another map of how it may have been configured.
  4. Kevin P. Hefferan has a fantastic series of images about the world’s continents as they may have lain at various ages of geologic history linked from his simple page about Rodinia.
  5. The University of Western Australia provides us with some maps of Rodinia.
