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.

900!!
W00T ! :)
Well, it always sounds just fine to me.
:)
Oh, crikey! I didn’t even see that!
Thanks! LOL!
LOL! I JUST had that come up on my FB feed!! LOL! :o])
Your Mum is funny gal. Now I understand where you get your sense of humor!
Oh, you have no idea of the trouble it gets me in to.
*Grin*
Good to know.
Yes, Moose, I think I do!! I come from the same family over here! ;o]
I noted with dismay that the elevated COVID clamp-down here in CA had flushed the hoarders out to COSTCO; they were borderline mobbing the paper products aisle, again.
I DID NOT see anybody rolling out with stax and stax; I think the “Limit 2 per customer” is still in place.
On the upside: ‘tis the season for CHEESE.
I bought some with literary connections:
A sheep’s milk Manchego made in the La Mancha region of Spain; and a blue Stilton from Nottingham, England for my girls who like Thea Stilton’s “Thea Sisters” — a vaguely “Charlie’s Angels”-esque Scholastic book series wherein the main characters are a group of five female mice who get swept into solving mysteries under the guidance of a female investigative journalist.
And I grabbed a wedge of Ashbrook; a raw milk artisan cheese out of a modest 100-cow dairy concern in Vermont.

“Only nine more days until the Advent Kitteh!”
Uuurrrrkk!
My head isn’t even into Thanksgiving mode, yet.
Mrs. HK wants to Go All In on the Christmas deco this year, so after I awaken from my turkey coma I know what I’m doing with my 3-day weekend. And that means THIS weekend will be invested getting the appropriate items out of storage.
And THEN — shopping, and my annual paean to capitalism.
NOW you’ve done it. I can risk anything but temptation, and this is it.
I’ve never heard of the place but the cheeses sound yummy. I do, however, like Stilton. And Hvarti. (Did I spell that right?)
*sigh*
Maybe next year... :o|
Some people here have had lights and trees up for the last three weeks. I guess they’re very tired of being cooped up.
I’m in the same mode for Thanksgiving this year as I was last year: Hungry Man dinner and a pumpkin pie.
Christmas, however, will be spent in AR with my Favorite Son and two youngest grandsons. :o]
I’m still waiting for folks to start showing up on MeWe, but either they don’t like me, or they’re just not changing from FB. Only the groups are posting.
Be veeeewy qwiet. We’we hunting wabbits.
I put the puppy out in 23 fs this morning. Mrs. ArGee wondered if cold could trigger a seizure. I told her I was usually fine.
Then, after she was done glaring my hair on fire, I told her we’d see. Apparently not every time at least.
Mrs. ArGee says canned goods are starting to thin out again, here.
I think individual decisions and market forces would have the Wal-Mart shelves full with stuff exactly proportionate to the rate at which said stuff flies off the shelves.
If there’s anything this country has down, it’s consumering. We can consumer like nobody’s business. Or like everybody’s business because it is.
A short interruption when things change is all there should ever, naturally, be.
Well, now we know where all the 8s went.
If it stops stopping, will it start starting?
Old saying: Man with two watches does not know what time it is.
Now think of this day and age when everything with a power source shows the time how confused we must be about when it is.
Since I stay away from canned goods and their high sodium content, I haven’t noticed. It’s a practice I got into when I was working, and though I can’t recall why I did it in the first place, I don’t do it in the second place because canned goods are hard to move!
But my diet is a little stranger than most people’s. I think it’s from living alone for so long.
w00t!
