University of Wyoming scientists have found evidence of continental collisions in Wyoming's Teton Range, similar to those in the Himalayas, dating to as early as 2.68 billion years ago.
The research, published Jan. 22 in the journal Geochimica et Cosmochimica Acta, shows that plate tectonics were operating in what is now western Wyoming long before the collisions that created the Himalayas starting 40 million years ago.
In fact, the remnants of tectonic activity in old rocks exposed in the Tetons point to the world's earliest known continent-continent collision, says Professor Carol Frost of UW's Department of Geology and Geophysics, lead author of the paper.
"While the Himalayas are the prime example of continent-continent collisions that take place due to plate tectonic motion today, our work suggests plate tectonics operated far, far back into the geologic past," Frost says.

Yes. It’s hard to all sort out. Those rocks were once the intrusions under volcanos. The same can be said about the granite most places.
??? Seriously
I’m sure he was driving a Range Rover.
Just a case of GAIA getting her rocks off.
It’s no wonder that I failed Stratigraphy. However, I did find a new subspecies of Conodont. Also found a Bellumnitella at the Hechinger site, Landover, Md. along with a small dinosaur knuckle (My daughter actually find that. I found the Mosasaur tooth and vertebrae).
Graptolites out near Route 81 near Luray Caverns. Kids loved them.
Just bragging. Oh, dozens of baseball and softball-sized Culcullaea Gigantia across from the Hechinger site, on Central Avenue (Giant clamshells/molds to you amateurs). Make great gifts and paperweights. About 60 million years old (somewhere between the Paleocene and the Eocene).
How about radioactive Glauconitic sands from the Vincetown Formation in New Jersey? Full of Bryozoa and Foraminarifera (spelling is way off). Little guys in shallow seas. About 120 Million years old. Kinda cute.
YES they are grand! I was there in 2013! Wish to go again!
Fascinating. Great avocation. Requires a better eye for detail than mine.
So the Tetons have been slapping together, is that what we are saying???
Nice to see the promise of this thread has been met! ;)
This thread would have been incomplete without pics.
#23 really took care of biz though.
LOL!
-——It’s not a static thing——
or in other words, what is , isn’t
LOL
If it’s not SUVs, it’s those darned Continentals!
I can see Russian from there...
(Sounded funny in muh head)
