Great overview. Watching on youtube I had the benefit of pausing here and there, which helped to absorb the information.
Excellent summary presentation, Tom! Lots to think about.
Well done; thanks for posting.
The strength of earths tectonic processes is amazing. The fact that Northern South America was souther south America in Laurentia times show you just how much we actually move albeit very slowly
I can't believe I let my family talk me out of becoming a geologist.
So Appalachians, Atlas Mountains, and Ouachita Range formed in the same Pangea collision? Forgive me, I'm not a geologist. Just a geology buff.
Great information dense talk! Thx
Very nice summary. I've been trying to find evidence from deep wells that confirm the hypothesis that post-rifting Mesozoic sediments overlie Paleozoic sediments in the areas shown to have crustal thinning (green areas in the figure at minute 13). Where have any wells encountered Paleozoic sediments under what's understood to be original locations of Louann Salt deposition?
Thank you for the helpful overview! Very interesting.
Wow! That was dense and super informative. I'm just now learning the basics of geology but I will definitely keep coming back to this video as I learn
Watch Nick Zentner and feel your brain warm.
I enjoyed that.
I would like to ask a question? You have an area marked Highland that I believe was volcanic. Could it be an ancient volcanic mountain there at one point?
Interesting though I wished he had not run through so much material in half the time it should have taken to explain this well. If he is like this at home he must have the most frustrated wife in town.
His wife passed away some years ago. He talks this way in his presentation because he has a lot of information to convey in a very short time. Lighten up.
damn dude, have some class
so when the land separated animals became smaller , look uso when the land separated animals became smaller , look up island animals shrinking. dinosaurs didn't die they shrank!. Land smaller animals smaller !!
some dinos descended into ostriches, others into hummingbirds, so...
At what point do you geologists from Texas and Mexico talk to the guys from the Pacific Northwest or the Scots? How do you explain a SYSTEM if you stay in your cubby-holes? I can see escarpments in NY and Scotland. PUT THE SYSTEM TOGETHER! You guys are too segmented. I travel to NW New Mexico/NE Arizona. I know the rocks say "swamp" at some point and riverine at another. Paleomagnetism, unless you're too orthodox. I'm only saying that if your theories don't match up with someone else's thousands of miles and millions of years away, then there needs to be RESOLUTION! Tie them together. One front.
