The Columbia supercontinent revisited

JG Meert, M Santosh - Gondwana Research, 2017 - Elsevier
Just over 15 years ago, a proposal forwarded by Rogers and Santosh (2002) posited the
existence of a pre-Rodinia supercontinent which they called Columbia. The conjecture …

The Columbia supercontinent: Retrospective, status, and a statistical assessment of paleomagnetic poles used in reconstructions

JG Meert, M Santosh - Gondwana Research, 2022 - Elsevier
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 …

[HTML][HTML] The boring billion?–Lid tectonics, continental growth and environmental change associated with the Columbia supercontinent

NMW Roberts - Geoscience Frontiers, 2013 - Elsevier
