Friday fold: passively folded marble
Posted by Callan Bentley
Here’s Baxter, last Friday, in Athens, Greece. He’s checking out some folds in the marble that’s everywhere in that city:
This is a lovely example of passive folding, where all the rock layers being folded have about the same viscosity (low viscosity contrast between layers). No buckling, as a result…
Enjoy the weekend, hopefully passively!
Perhaps a bit of quasi-stylolitization as well!
