The Columbia supercontinent: Retrospective, status, and a statistical assessment of paleomagnetic poles used in reconstructions
The proposal that a Paleo-Mesoproterozoic supercontinent, Columbia, preceded the
existence of Rodinia was forwarded in 2002. A similar proposal that same year provided a …
