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.

Ah, yes... Kitteh reading the morning paper. Does he get tea with that?
Good morning.
The pills have been sorted, but now I have to go hang the clothes in the closet and make the bed. I plan to leave for Walmart at 0600, so I can drive home when it’s a little lighter than pitch black. Otherwise, I’ll miss my turn. Or take the corner so fast I’m in danger of tipping over!
I think nine hours isn’t quite enough sleep for me, but I’ll try to make it work. I realize feeling tired when I wake up is part of the disease but I never get used to it.
Yeah, me too, only maybe not quite so widely!
One had to have a great appreciation for British WWII aircraft to understand it properly!
I got it!
Nobody is up here, just me and cats. DP had some work thing last night. Shannon expects her meat (and her pill): she’s lurking on the kitchen mat, hating. I think I’ll go get the newspaper first.
Yes, T-c, I knew you would! :o])
Nobody is up here, just me. Missing the chirpy little birds.
The weather looks ugly all across the Midwest. Cabot is in for some very cold weather. Unngh. I think they have more winter than we do.
Morning TC.
“Very scenic! I bet it’s haunted.”
Haunted in a very organised way. No random appearances . All to a very strict schedule.
Need to visit Germany one day.
Yesterday’s snow all disappeared but still a little on the chilly side.
Good morning. Happy Tuesday.
It does seem news of the last year or so has been impacted by a black cat, no?
It’s above freezing this morning, a nice change ... although DP says it’s raining, which makes me glad we got out yesterday while it was sunny.
I would like to see Germany ... although I recall reading that the Czech Republic has a higher density of castles than any other part of Europe.
That’s one interpretation. Could be worse ... could have been a meteor.
I would have voted for SMOD, but it wasn’t on the ballot.
Who was it on which show who was always saying, “Take me now, Lord”?
I’m ready.
Back from Walmart, and because I mistimed my trip, I also missed my turn and had to make a U-turn on the top of a small hill and hope no one came over the crest from either direction.
When we were in Germany, the Czech Republic was a communist bloc country and we were not allowed to go anywhere near it. The closest we could get was Transylvania, and for reasons I prefer not to divulge, I never saw nearly as much of Germany as I would loved to have done.
So, I was just looking at a note about Sen. Grassley calling out President Biden for requiring a COVID test for people who deplane in this country, but welcoming people who walk in illegally with open arms.
What we need is Rod Serling to explain how we wound up in the Twilight Zone.
I think I forgot to mention yesterday that we had gone 2 months without the puppy having a seizure.
Congratulations on the puppy! So are we to surmise that it was the medication that was at fault, for making the puppy suffer?
That’s what we are surmising.
Well, I certainly hope she’s over it, now.
As do we. We’re somewhat optimistic. But she’s not quite 10 months old, and epilepsy usually shows between 1 and 2 years old, so it could still return.
I hope she shows no more inclination for epilepsy, no matter what her age. At any rate, I’ll just keep all of you on my prayer list.
Glad to hear it!
Maybe it’s time to read “Call of Cthulhu” again.
I’d never heard of that book until FR. Maybe I need to check it out.
Which reminds me: Do you like action fiction?
