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.

All Fridays are happy in their own way.
Yes, indeed! I woke up again, and that’s a good thing. ;o]
We have all our soil presentations arranged. I wish I could go back to college and learn more about all this, like Tom. Maybe in a few years, if DP gets an early retirement buyout ...
I’d like to go back to college and learn anthropology or take some classes in astronomy, but after I get moved, I’m going to have to concentrate on the genealogy. There is no way I would have time for classes, unless I could figure out how to function on four hours of sleep a night!
Good luck on all the presentations! I hope the afternoon is fulfilling for all of you. ;o]
There are plenty of videos and online courses, but it’s not the same.
You’re absolutely right about that!
w00t!
3 for 3.
Our soil class went very well. I’m told Vlad didn’t get a fit of the giggles but spoke intelligibly about soil levels and erosion.
Thank you.
Brian sounds like a really nice neighbor, getting up several times throughout the night to let the dog out. How do you stop a dog from barking? I've always had large, very quiet dogs until we raised the current little dog.
U2.
My left eye has already had laser surgery, so its time for the right one, so I can see to put my make-up on, among other things. ;o]
Brian doesn’t get up several times throughout the night. The latest he lets the dog out is 1900. My sleep schedule is such that I’m asleep by 1800 but I’ve been struggling with insomnia since the end of June.
I’ve had small dogs, and I’ve always been aware of and respectful to my neighbors and brought the dogs in when they began to bark. They were seldom ever left outside on their own.
I keep waiting for someone else to take them, but... :o|
I’m glad it went well!
Vlad has always had trouble with The Giggles, hasn’t he? I’m afraid, had I been there, and he had gotten the giggles, I would have joined in!
My goodness! An early morning floof!
Good morning!
That little kitteh has such a sweet little face.
Happy Birthday to Tom!
It’s a nervous reaction. A few years ago, he would sometime burst into tears when he got nervous, but he’s outgrown it. However, earlier this week he was getting giggly reading the soil manual with James and me.
All the teen science boys, not just mine, did well yesterday, I hear. Vlad said the other two with his group were long-winded, though, so he didn’t cover all his erosion facts.
My topic, the County Soil Survey, was very interesting. A person thinking of buying property in the county should study it carefully.
I got a text at 0230 this morning. HAH! I was already up and dressed. :o]
Favorite Daughter was at work with her Significant Other. They both work in a sleep lab. During the day, she processes the results of the patients he oversees at night.
And to think: she started to work in a lab in Vegas, processing specimens — then moved into phlebotomy. Now this.
It’s good to have a marketable skill!
I need to get dressed in a few minutes and go help cook stew for a Boy Scouts fundraiser. It’s my compulsion to Make Myself Useful.
And with that, I’m outta here. Catch you later, maybe about lunchtime EDT, after choir.
