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! It’s kind of cold here, but it isn’t raining.
I need to call the dentist, the dermatologist, the vet, and my hairdresser today.
Happy Monday.
Cold and windy here. It doesn’t feel much like spring.
I slept about an hour and 20 minutes.
But then I managed to drag myself up and out of bed and get the laundry hung up.
I got cold when I was up in the night, and as usual, it settled in my lower back. It will remain tight, cold and achy all day. I wish my office chair had a heater in the backrest.
A heated office chair sounds really nice!
There. I fixed it! ;o]
The Altima has heated seats, which can be nice. However, the switches are located where they often get turned on by accident.
Amazon has the chairs. I just wish I had thought of it last week.
It would be so nice to ease the pain without having to wait for bedtime and my heated mattress pad.
The people I got the truck from said they’re sending me out a new wheel, and that it should be here by the end of the week.
Great news! Just wheeling it into the bedroom on one wheel was enough to tell me I had made the right decision in adding the wheels to the purchase!
Very exciting! I like wheels, myself.
Please know that I stand with your taller ants.
I don’t know what it means to stand with something, but I can assure you I do it all the time.
I just realized. I wrote “truck” instead of “trunk.” I’m glad you know me...
Stand tall!
Don’t you fall.
Oh, wait. Now I’m showing my age.
I’m a taller aunt; does that count?
I noticed, too, and figured it was “trunk,” but “truck” could have meant your loading dolly, too.
DP and I looked at rocks and agreed that we like brown. Then I had a nap with Jake.
Golly. Brown rocks. How are they to be used? Large river rocks? Small ones? This is sounding fun!
I got a text from FedEx saying the wheel is on the way, and I gotta tell ya — I’d recommend this place!
Cement rocks, mostly, because they’re about half the price of real rocks. They’re going to be a large patio with a fire pit and various paths that will allow us to move around the back yard without needing galoshes.
Good morning to you and the pastel kitteh! ;o]
I sorted the pills, folded the clothes, made the bed, and got my list ready for Walmart. I need to go wash my face off and comb my head out.
I think I’ve figured out what’s wrong with the library site, but I can’t play with it until I get back from Walmart.
The weather is still being ugly but I’ll just have to wait on that... The gal I talked to yesterday said we go from winter to summer here. In Vegas it was Summer and Christmas. In Alaska, it’s Winter and the Fourth of July. Ah well...
