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

[HTML][HTML] On the enigmatic mid-Proterozoic: Single-lid versus plate tectonics
Abstract The mid-Proterozoic (ca. 1850–850 Ma) is a peculiar period of Earth history in many
respects: ophiolites and passive margins of this age are rare, whereas anorthosite and A …
