Supercontinents and the Pacific Northwest - Nick Zentner

Hello, no time really, it’s Meltdown weekend, but in relaxing I came on a geology lecture by perhaps the greatest geology lecturer around, Nick Zentner from Washington.

No time to get into that just now either - But how may of you know about the Supercontinent Columbia?

I was vaguely aware there must have been something back before Rodinia, but that was musings. Now the serious guys, real experts and scientists have collected enough information so that conclusion are being made. Of course with the obvious caveat that more information will no doubt improve and possibly realign the story.

Pangea 200~300 MYA

Rodinia 750~1100 MYA

Columbia 1400~1800 MYA

Unless you are reading the literature, I’ll bet you’ll discover some things you never thought of before. It’s really amazing the details geologists have been able to unravel.
