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.

I would have copied, as well because though I am a good speller, my tongue (and fingers) would trip a lot over some of the words in this article.
But how interesting! A sponge as a symbol of love! :o])
I had some girlfriends like that back in the day.
LOL! I never knew any guys with money, because I grew up in a rural community. Orchards, cattle, sheep, sugar beets. Jeans and a white shirt were considered dress-up.
Starched and ironed!
I like beets.
Ah, that was clever! Jake likes newspapers, so maybe he’s ambitious for a journalistic career.
I’m going to make a casserole now.
The casserole is ready to go in the pans. I think I’ll clean the stove, next.
I do too, but these are sugar beets. The alternative to cane sugar. They also grow onions there. ;o])
I love onions, too. I bought more today.
You doing okay this afternoon? Kathleen’s riding lesson was postponed on account of cold and downpour, so I have time to clean the stove and stuff.
‘Face, one of the little ArGees is here this week and is binge-watching some show on NBC with Mrs. ArGee. It’s about a couple of brits who buy a castle in France and renovate it to be their home and then destination wedding resort. It sounded like your cuppa-cuppa.
They’re watching on the internet on some streaming service called Peacock. Some shows on Peacock cost, but this one is free. I have no doubt you could find it on your debice when the libary hasn’t been helpful with its midsommer murders.
I just did the Zion National Park puzzle. Pretty picture!
Would that show be “Dirty Rotten Scoundrels?” Or not.
I’ve never heard of Peacock but I’ll check it out, just in case. Thanks!
My dad loved onions. Most nights he would eat a dry cheese and onion sandwich, and on reflection, I’m thinking it was because that’s what was available when he was growing up. I don’t care for raw onions, but it seems in my family, I was the odd one out. Green onions, Vidalia onions, red onions, pearl onions — everyone liked onions but me. I like them cooked in other foods, I like onion rings, and have even been known to roast them, but not eat them raw.
I’m OK, thanks. Not great, but it’ll pass. Today is another day and I’ll get through it.

Good morning. Glad you’re okay, even if you’re not great!
The rain has stopped here, but it’s cold. Jake went out.
Have a Guinness!
Thanks. It’s warmer that it has been, but will be cloudy this morning.
I’m glad you did the puzzle of Zion Park. My thing is iris blossoms. I was doing roses, but it got so they weren’t much of a challenge.
No telling what I’ll do when I’ve lost interest in the iris. Probably fractals.
Today is my Favorite Daughter-in-Law’s birthday, and I’m sure she turned 39 again.
Good Happy St Paddy’s Day!
(How does one get a cat to play dress-up?)
I think you’d have to sedate the cat. Perhaps with Guinness ...
Happy birthday to your daughter-in-law. I vaguely remember being 39, but I’ll have no problem with being 55 on my next birthday.
