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.

Sounds like Supertramp.
I’m pretty old.
And my feet are cold.
Yea...on looking closer. Thanks. ;o]
Amazon has leg warmers. I think your feet might be warmer if your ankles were warmer. You could get them faster than if I sent them to you. I swear by them for cold feet!
Maybe I need insulated ski pants!
Did I want you for some reason?
Leg warmers are cheaper! LOL!
Or...if you had a fur coat like mine, you wouldn’t be cold!
Good morning.
I’ve been busy but I have nothing to show for it.
The wind was nil yesterday afternoon, and it was so nice to not have the plastic flapping, but now, the wind is up again. I think I understand how the folks in the OK Dust Bowl felt, with the wind blowing constantly. I thought my apartment in Vegas had a lot of dust, but this is three or four times as bad. Almost two weeks, now with seldom a let-up.
But it’s a great day to be alive so I can write this stuff in my journal, then look back next year and laugh!!
Good morning. It’s cold and gray here, but I’m told we might have sun later. Everything is very wet. At least we don’t have a flooded septic system, like some of our friends who aren’t on county sewers!
It’s supposed to be sunny and windy this morning, but overcast this afternoon. I have no idea if the barometer will change. The storm glass sure hasn’t!
So, now that I’ve wasted half my morning, I’ll get busy with the jobs at hand. *sheesh*
We have choir this morning. Then we’ll see what. DP is talking about going shopping with Tom. It’s fun for them!
I just paid most of my bills. I wasn’t fun for me. I can walk some of the payments over to the outgoing mail at some point before 1000, but the way I feel, it may have to wait until Monday.
I don’t feel like shopping at all. At least I don’t have to do it until Tuesday. :o]
I could pay the house payment, but there’s no point until Monday, so I won’t.
DP and Tom are going to run, and then ... something.
I like it when I can say, “I’d like to pay it, but there’s no point until...” but it usually gets garbled into something more like, “OhNO! I forgot to pay that bill AGAIN???” Or, more usually, “How did I miss THAT one?”
I’m cold, even though I have a long-sleeved T-shirt and a hoodie on. The sun is shining but its sill very much below 40° out.
How was choir practice? Do you do that by Zoom? I can see others, but they can’t see me, so Zoom of off the table.
Our people come over, in ones and twos, for choir. It was fine. Asuncion is out this week because she’s taking care of her daughter, who had surgery, so I’m doing higher-pitched songs with two of the other ladies.
I hate higher-pitched songs. I’m having trouble these days with staying in the tenor range, as my voice wants to slide down to baritone. I hate that. It’s especially bad when I first wake up.
Sharon doesn’t like to sit next to me when we sing because she sings alto and expects me to sing it as well. Nope. I can’t get that high without sounding like I’m re-entering puberty.
Asunscion’s pitch has dropped in the last decade, but this weekend’s other ladies are in their early 40s and have a bit higher range.
That helps. I miss singing in the choir. That was always a fun thing to do, and twice, I got to sing with very large choirs. Not many tenors, but we made up for it in quality!
I haven’t been in a large choir since we left San Antonio, more than 25 years ago. Maybe someday.
It’s probably been that long since I sang in a large one...I’m thinking maybe 1988...?
For a while there, I thought I had forgotten how to sing. I had a keyboard program in my Nook, but then, B&N decided to only carry books and not games and I couldn’t get upgrades. It helped me to pick out the notes for the hymns we were working on. Now, I don’t have a keyboard. Maybe I should check Amazon or eBay...
Hmmm...
