A team of geologists at the University of Houston College of Natural Sciences and Mathematics believes they have found the lost plate in northern Canada by using existing mantle tomography images—similar to a CT scan of the earth's interior. The findings, published in Geological Society of America Bulletin, could help geologists better predict volcanic hazards as well as mineral and hydrocarbon deposits.
"Volcanoes form at plate boundaries, and the more plates you have, the more volcanoes you have," said Jonny Wu, assistant professor of geology in the Department of Earth and Atmospheric Sciences. "Volcanoes also affect climate change. So, when you are trying to model the earth and understand how climate has changed since time, you really want to know how many volcanoes there have been on earth."
Wu and Spencer Fuston, a third-year geology doctoral student, applied a technique developed by the UH Center for Tectonics and Tomography called slab unfolding to reconstruct what tectonic plates in the Pacific Ocean looked like during the early Cenozoic Era. The rigid outermost shell of Earth, or lithosphere, is broken into tectonic plates and geologists have always known there were two plates in the Pacific Ocean at that time called Kula and Farallon. But there has been discussion about a potential third plate, Resurrection, having formed a special type of volcanic belt along Alaska and Washington State.
Using 3-D mapping technology, Fuston applied the slab unfolding technique to the mantle tomography images to pull out the subducted plates before unfolding and stretching them to their original shapes.

Unnngh.
I had a nap with Jake, and I’m about to go back to work chopping.
Going to cheat on this one...
Just sayin'...
Just like at camp!
Good job!
“It’s 100 yards to the outhouse... Willie make it...”
It’s been a while. I think Face grabbed the last couple... I still feel bad that I don’t have as much time to be here as I used to...
We’re always glad to see you when you can stop by.
Is it Tuesday already? I appear to have missed Monday. And DC dropped in with the nearly great Billy Idol and the slaughterhouse kitteh. That’s what I get for working for a living.
Happy Tuesday!
So true. Good morning!
It’s trash day here. Tom the Son is coming over in an hour or so. I offered him some gas money to take Cub Scout Day Camp forms Uptown for me.
‘Face reporting for duty, Sirs and Ma’am.
Sorry I was AWOL, but CFIDS bit me in the backside and it was either retreat and Do No Harm, or stay and be banned and/or suspended for life by my FRiends. I’m not out of the woods, yet, but if I slip, maybe all y’all can forgive me. Trust me, it won’t be personal and it won’t be intentional. It will just be CFIDS at work.
Thanks for the GIF, DC! I smiled when I saw it. It was good to see so many posts from you. You’ve been sorely missed here, and you’re appreciated every time you visit, even if it’s only a Drive-By post.
The good news is that most of the books are packed, and a lot of stuff is organized for packing, which was going to take place today, but I think I’ll work on filing the last bunch of papers. Tomorrow, I can get busy on the packing again.
I have to take a day Off in between a day of Stuff or I’ll be sick again, and I don’t want to do that. So paperwork it is today. And the liberry. Yesterday was extremely productive, so if I brag about it, please forgive me. It is an Accomplishment.
(And I have a very sore lower back to prove it!)
Good morning. I hear someone running water upstairs, so it will soon be time to officially start the day. I’ll get a kitteh first.
It was raining when I went out for the newspaper, which was delivered for a change.
*tagline*
What a sweet floof!
Good morning.
I’m headed for the shower. I hope it takes some of the sting away.
