These images come from Lilly Wilson, an undergraduate geology student at the University of Bristol:

Here’s her original tweet, which has 4 images:

Boscastle, Cornwall is home to some of the most spectacular folding and quartz veins I’ve seen. Every hillside you look there’s a new array of mangled rocks from the Variscan Orogeny! pic.twitter.com/B9tIkvBxna

For my American readers, the Variscan is the European equivalent of the Alleghanian Orogeny in the Appalachian mountain belt. At the same time these rocks were being deformed, similar strata were experiencing similar folding in my backyard.

Lilly should also be commended for her choice of field assistant, who appears to be a shrewd judge of structural geological character:

Great rocks, excellent photos, and a thoughtful pooch, too – excellent tweeting! Thanks for sharing, Lilly.

Happy Friday all!
