Friday fold: Machir Bay I

Posted by Callan

Today’s Friday fold is one of those lovely gems that weather out in three dimensions. I spent a few quality moments with it this summer on the north side of Machir Bay, Islay, Scotland.

Lovely! Give it a little twist to the right, and it looks like this:

The fold overprints foliation or bedding in lightly metamorphosed metasedimentary rock of the Colonsay Group (Neoproterozoic).

Happy Friday!
