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.

Sorry I missed you, but my mornings are not my own. Now I need to take another dose of pills.
My brain feels rather linty today.
I was useful. I cut up a bag of onion, and dished up about 100 servings of banana puddings and maybe 50 of Brunswick stew before I had to flee back to choir.
Sean Connery has died.
It’s nice to be useful! Especially for the needy. Or the just plain hungry.
I just finished the dishes, and realized I need a new pair of gloves. Even when my hands were “lily-white” as my late, ex-mother-in-law said, I’ve had a problem with my hands getting pruney. They do it even in the shower, which doesn’t last long at all, so I wear gloves to do the dishes.
That’s probably TMI.
Yes, I was going to mention Sir Sean, but you had already gone when I found out. Suddenly, FB was bombarded with the news. So sad. He was a force to be reckoned with, for sure.
Sad in a way, but 90, so there you go.
Choir is done. Now Pat is going to drive me to the library to return some books.
I hate to be trite, but he did live a good, full life, so 90 years would have provided a lot of memories. And the Bahamas is as pleasant a place to die in as any, I guess.
I’m going to make a meat loaf and wait for the mail. I’ll probably take the trash out, as well, though this is a day when The Punies want to visit. I suspected they weren’t far away, by the symptoms I’ve been having, so I’ll just take it as easy as I can. There’s that doctor’s appointment, looming, on Monday.
Thanks for the ping.
Two people bitten by rabid cat in PG county MD....a brown tabby.
You’re welcome.
It wasn’t Jake. He’s vaccinated.
Driving survived, nap accomplished. Tom the Birthday Son decided he wanted to go to the used book store.
Much later, we’ve bought Chinese takeout for the starving brothers and are headed home.
Just when you thought Hallowe’en was a benign holiday... ;o]
For several days, now, I’ve been struggling with pain in my right knee that radiates down my leg, and it seems there’s no way to stop it or ease it. Sitting makes it worse, standing makes it worse, walking makes it worse. Lying down seems to be the only way to ease it but I can’t lie down all day.
So I’m open to suggestions. I’ve tried ice, and no ice but I haven’t tried heat.
Try heat! Or try moist heat. I think that’s what the physical therapist who was working the night desk in my mom’s building told her to do for her knee.
And good morning! The staff at the used book store were very complimentary about my Day of the Dead shawl!
I was wondering if you had occasion to wear it, and of course, with All Soul’s Day falling on Sunday, well... ;o]
In honor of said day, I’m wearing my Day of the Dead leggings, though they’re only good for one wearing. They get baggy in the knees and lose all their leggy appeal. LuLaRoe leggings are much better, but these are fitting for today.
I got some spider leggings in the teenage-girls section at Walmart. (Have to remember to get large instead of small in that section.)
Today is All Saints Day. Monday is All Souls’ Day. And the whole month of November is good for skulls and stuff.
Pretty little floof!
Good morning.
The knee feels much better this morning, but it was a long night. I will try hot, moist heat. Until recently, that has been my go-do remedy for aches and pains but then I began to think that if the joint is inflamed, it needs to be cooled. There may be a flaw in that thinking.
Camilla is taking an interest in some toys in her cage that I put in there to try and distract her. It’s only been the last couple of days that she’s taken an interest in them, so maybe she’s coming out of whatever her funk was.
Gonzo is practicing his repertoire of songs, so between the two of them, all is well in Muppetbirdland.
I’m glad your knee is better and the birds are chirpy!
With a new month beginning, I’m going back to making Smart Choices for my health and fitness ... so I’m about to get on the treadmill with a backlog of Jonah Goldberg podcasts.
It’s raining here. Catz are mad. Kathleen put on her rain boots and went to the playground to get muddy.
I’m just glad the birds are acting like normal birds.
How odd to see so much daylight at this time... I have to fix the clock on the laptop, and the analog clock I refer to during the day has finally decided to die — after about 30 years. I think I got it in 1992 for $5 on sale at Osco Drug before it was sold to Long’s Drug and then Lucky Market. I loved it when I first saw it and have loved it every day since, and even through 50 drops and tip-overs, it still worked in a wonky way. No more. It’s dead, Jim.
