re: #312 celticdragon

LOL! Cool!

The Laramide Orogeny is the name of the event that formed the Rockies. Frictional coupling between the Fallaron slab and North America generated massive crustal shortening (like tens to hundreds of kilometers) as giant low angle thrust faults stacked up sheets of rock on top of one another. My structures class is about over, and I have absolutely loved it!

Low angle thrust faults are responsible for a lot of structures in the Appalachians, too (but you would expect that on a collisional plate margin).

Anyone want to debate the science?
