      That’s cool. I want to travel to the Canadian Northern islands someday and see the rocks there, which are likely that old. Some deposits on Michigan’s upper peninsula also date back to the Hadean, apparently.

          We are in areas of high volcanism!

          I was in Iceland a few months ago, and in some areas the rocks are only tens of years old. There are entire plains of lava flows that are only a few thousand years old. (Same for Hawaii, too.)
