Another good example of ptygmatic (tig mat tic) folding. There are hundreds out in cyberspace. I found this while collecting data for my MS back in the summer of 99.
I found this ptygmatic pair very near (less than 25 meters) THIS set of conjugate quartz veins all of which is located at the southwestern extent of my field area. An area I called Buttonwood Hill. If you look closely at the photo in the upper right plunge of the folded vein and hinge are visible. Don't ask me to recall the angle. Its just a cool geologic feature photograph.
Other posts from my thesis area are: HERE and HERE.

Interesting formation; I've never seen it other than in pictures.
