Friday folds: Continuing contorted Conestoga carbonates
Posted by Callan Bentley
Happy Friday to you all! I’ve previously showcased folded Conestoga Formation on the campus of Millersville University in Pennsylvania for the Friday fold. Today we’ll go a bit further afield, to the Burle Business Park on New Holland Ave in Lancaster. There are plenty of nice outcrops of Conestoga Formation limestone exposed there, and they have a few cool things to show us.
I visited this site on a field trip during June’s Eastern Section meeting of the National Association of Geoscience Teachers. Here’s Martin Schmidt, David Brink-Roby, and Don Duggan-Haas traipsing across one of the exposures:
Sedimentologically, the site is noteworthy because it includes some submarine landslide breccias, as seen here:
But for me, the best part was the plethora of sweet folds:
Happy Friday!
As a friendly reminder, I welcome submissions of “Guest Friday folds” for the blog. Just shoot me an email if you’ve got some cool folds to share!
