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.

They’d better!
The youth are fighting over food, just like they were in 2016. Not all the same youth, but basically interchangeable.
They did! Of course. The pharmacist looked totally lost when he picked up the inhaler, like he had no idea how to work it. And maybe he didn’t.
Anyway, it was a decent spate of errands, and I’m home until Friday when I have to go back to the library.
I got complimented on my Kermit leggings, and that made my day immensely brighter! I wear them to cheer myself up but the doc broke into song when she saw them: It’s not easy being green... :o])
It’s nice when someone has a good time like that. I might go to the library tomorrow, but right now it’s naptime. The package arrived, but I’m saving it until after nap.
I’ve heard history has a way of repeating itself.
But I never get the same paycheck twice.
You’ll have to tell me what’s in the package because I’ve slept since I mailed it! ;o]
I’m glad the package got there, anyway.
People are so grumpy since Covid hit, and I try to make every encounter a happy one. Smiles are hidden these days, so I have to rely on the old CSR training. Some days, nothing works.
That’s odd...when I worked for the county, my paychecks were always the same. Until I started getting sick, and then it was like - who took my money?
For me it’s “Why are there so many songs about rainbows?”
I was waiting up, really I was, but my eyelids are beginning to slam shut so I need to head down the hall and let them do what they do best.
See ya tomorry, then...
Sorry, I had to cook! See you tomorrow.
Someone watched “Romancing The Stone” one time too many.
I’d be happy with the yacht, tho.

Oh, so exciting, just like Christmas or better! The distinctive local apparrel, the very big socks for my very big feet! Cat pictures! And a sign to keep the wrong types out of my space!
The local apparel isn’t always available, and some of it is “tacky.” There’s only one place in town that carries it, and that’s Lin’s. The socks are only at the same place, and I have to take what I can get! And did I add the bookmarks? “Out of sight, out of mind.”
The sign, of course, is reversible! Mood swings and all that! ;o]
Yes, it IS like Christmas!
Nah. I only saw the movie once, because it wasn’t all that, but I’ve known since probably the age of 10 that most emeralds come from Columbia. It’s my birthstone, and I love it — such a beautiful, deep green! It’s also said that a person wearing emeralds can’t be hypnotized, so there’s that, too. ;o]
*tagline*
Kitteh wants to know if dis is a day.
Good morning.
It would seem nothing got done yesterday. This morning, I’m going to try and finish up the shredding, because I’m tired of tripping over the half-full bag of shreds and the stack of papers waiting to be shredded. I’ll probably take three bags out before I’m done. Or maybe four.
I’m also trying to decide if finding things would be easier from an album or from an indexed file. I hate making decisions, these days, but simplifying my life is paramount. Any suggestions would be appreciated.
The wind is blowing again. I finally figured out why the plastic doesn’t want to stay in place over the swamp cooler vent. It’s because the canvas cover over the unit is about half off, so the wind gets in easily. Chuck was on the roof twice in the last year to uncover and cover Rocky’s cooler, and it would only have been about a 10’ walk over to my cooler to reposition the cover here.
I need to move...
Good morning. Happy Friday Eve!
