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.

Soon, there will be a chicken casserole.
I’ll just eat the cold chicken. I’ll make a sandwich or not, and just eat it until there isn’t much left but bones. And Tuesday, I’ll get a whole chicken, some new baby potatoes and some baby carrots and roast the whole shebang.
Meanwhile, I have a full-blown migraine and it’s affecting my vision. I got up and BOOM! it was there. For my next trick, I’ll go take a shower and see how I feel when I get done. Not a day to be doing things, I think.
Sorry about the migraine. I just had a cat batting toys around the bathroom floor at 4:45.
Awww...I could take that little squeeful floof home for a nap!
Good morning.
Thanks for commiserating. The shower has been had but the migraine is settling in for the long haul. But I’ll deal with it.
Favorite Daughter is ailing. She’ll go to a “drive-in” testing site today for the COVID test, but she’s in the high-risk group because she was on Lyrica for her back pain (Slipped disc?) and it damaged her heart. If it ain’t one darn thing...
I got in on the second half of a NOVA production about the Colosseum. A cage was reconstructed to bring an animal in, and that was pretty exciting, because the thing had to be constructed outside the Colosseum, then placed inside it in precisely the exact spot by a crane.
The Romans even used a calcium supplement drink made with volcanic ash to strengthen the bones of the gladiators. What amazing things we can learn from history!
Good morning. I’m sorry to hear your daughter is poorly. I hope she finds she doesn’t have Covid.
I need to make up another screen of soil science Jeopardy questions this morning. Maybe there will be a Patrick Driving Adventure too.
Her mother died from a heart attack and I’ve always been a little on edge when it comes to heart-related illness. When FD was 10 she had Scarlet Fever so it explains why her illnesses are so deep and long. It just takes her forever to recover.
I’m hoping it isn’t Covid as well, but she was exposed to it last week, so it wouldn’t be a surprise.
It’s strange to think of someone my own age having scarlet fever. That’s like historic.
Well, she was a child when she had it, but still, that puts me in the pre-historic. ;o]
The letter to Charlie is done, so now, I’ll head over to the mail drop so I don’t have to drive to the post orifice today. I just want to stay home and rest up. I don’t know how the migraine is going to affect my day, but the less I do, the less chance there is of messing it up due to pain.
Good morning. Happy Friday.
Wake up, Kitteh. Sleep is for Mondays.
So sorry about the migraine. I outgrew the pain, but the vision thing is annoying. Also, when they’re really bad I can’t call up the words I want. But that’s pretty rare these days.
I think you should stay home and rest up.
It’s happy Friday here. I just finished Soil Vocabulary Jeopardy screens. Next, I will cut up apples.
Good morning and Frappy High Day to you, too!
Thanks, ArGee.
The migraines morphed when I was in my 40s to the ocular and then about 10-15 years later, they morphed again and would play “Switch.” Pain one time, vision the next. Then they morphed again in a combination of the two.
The word thing began to go when CFIDS came along, so I don’t even wait for it to “get better as soon as the migraine quits.” It won’t. Some days, the words just won’t come. Period.
Trust me: I’m staying home. Since I finally have another plastic file box (I need one more) I’ll start putting things from the desk in it. I have plenty of hanging file folders as well as regular, so it should be easy.
I think this will be the last move for the wooden file, though. I got it the first year NASCAR went to Vegas (96?) and it has been halfway across the country and back. I had two, but one of them died about four moves ago.
Anyway, I can sit here and put things in the file box and then arrange them later. Something. The right side of my head is useless. :o|
You got all the Fives.
Keeping them until I get two more! Then I’ll have a full house: Fives and fives! YAY!
A wit!
We finished “Henry IV, Part II.” He died.
I have a tendency to lose track of who is where, but for my fellow New York denizens, some possible good news.

The URL says a lot of what the article says. The article has some details, but from a NYC perspective.
Yes, but you're only half right! ;o]
I actually did a task. I cleaned the bathroom. Did me in, though. However, the wind is up enough to set the chimes to singing the song of their people, so that makes the bathroom-cleaning worth it.
