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.

Good morning. Happy Friday Eve!
Happy Thorsday to you. Speaking of Thor, I need to call Tom the Son.
Today is not only Thor’s Day, Friday Eve and Friday the 13th disguised as Thursday, but it’s my Favorite Daughter’s birthday! I’d tell you which one, but that would be giving away my own age, so I’ll just say it’s easy to have kids when you’re 15. ;o]
It’s supposed to get into the 90s today, but I’ll be in bed by the time it hits that point. Before I decided to change my schedule, I knew I’d be asleep before the bedroom got warm. Now? Not so much!
I know how old your favorite daughter is, because so am I.
Don’t forget to call Arkansas. We’re on our way out, leaving James to do household tasks.
So I’m right: It is easy to have kids when you’re 15!
I did call Arkansas. I’m waiting for a return call, since the gal was busy with a client.
Vlad is in the finals of the Monopoly tournament. I’m watching some girls on the playground and listening to Tom the Mocker make an astounding variety of sounds, including several kinds of car alarms.
Can Tom the Mocker do an impression of the Biden administration doing something right?
Oh, wait, he would need to have heard that once first.
Nevermind.
Good luck to Vlad!
One of the mockers in Henderson used to bark. There was a nasty little hairy dog that kept half the neighborhood up at night, and it was just the right pitch for the mocker to like. It was hilarious to hear a “bark! bark-bark!” coming from the top of one of the big pine trees.
Vlad won the Monopoly Tournament. The prize was a $20 Visa gift card, which he is now trying to figure out how to use.
Him has to activate it first, with the 800 number on the back.
Congratulations, Vlad!
He figured it out and ordered a new mp3 player on eBay. His old one stopped holding a charge.
It bites when old electronics stop holding a charge. That’s when I set them aside for eventual donation to CPFS.
I saw Chuck come into the complex, so I walked over and told him of the incident with Lona and her nasty dog Chloe, and asked if he wanted it in writing. He said no, but he’s not very happy with her.
I may be back. The day didn’t turn out the way I wanted, but most days seldom do.
So I’ll go play mahjong for a bit, then study Scriptures and then maybe read something uplifting. Somewhere in there might be a break for station identification or several commercial interruptions but in any event I’ll be back, eventually! ;o]
I had a bit of nap. Now I’m heating up the sauce I made earlier so we can have spaghetti for supper.
Mrs ArGee is at some appointment with her folks. I am listening to the dog vocalizing out the window because two people are daring to talk at the back of their car RIGHT OUTSIDE. How DARE they.
She is scheduled to be spayed tomorrow. I’ve never waited so long with a dog before. We’ll see how everything goes.
I hope the surgery goes excellently, Lj.
I have a Zoom meeting tonight at 7:30. The Spanish Volunteers Committee keeps vampires’ hours! I don’t have anything much to report, but I need to be there anyway. Maybe this weekend I’ll try contacting my vanished musicians, the Guatemalan electronic pop band and the guitar-playing boy from Venezuela.
I, too, hope dog’s surgery goes well. She must be dreading each visit to the smellish place.
I was down, then I got up, because. It wasn’t quite so bad tonight. Usually, I’m fighting to stay awake, going into contortions to get the blood moving, yelling at myself to wake up and finding a bazillion reasons to get out of bed.
This time up, I’ll get a short bottle of very cold water (some that’s been in the fridge longer than 24 hours) and go back to bed. Maybe I’ll manage to stay awake until 1900.
Finally finished the Spanish Volunteers Meeting. They do go on ... but at least nobody had to drive home afterward.
