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.

Prayers for US All !!!
Thank you, NtI! The very best to you and yours. ;o]
W00t! Good job!
Congratulations on going back to bed. I’ve been busy.
The mince pie is out of the oven and next is to make the hard sauce. But one thing at a time.
I don’t know if I’ll get anything else done today, but at least the letter to Charlie is in the outgoing mailbox. I’ll write to my Favorite Son tomorrow. I started a letter to him last Saturday, but only got about two paragraphs in and my mind went blank. Maybe tomorrow, I’ll have better luck.
This morning, I decided to try wearing some of my leggings from the days in the office, and I can’t believe the difference they have made. Usually by this time of day, I’m freezing and have to either put on a jacket or the vest to keep warm until bedtime. This feels good! ;o]
I wear leggings under my skirts all the time in this weather.
To those who have lost loved ones, you have my heartfelt condolences.
To those who have had new beginnings, congratulations and keep the faith in God and our country.
To those who have been or are ill, may your recovery be quick, or if not, may you will still be able to find gratitude.
And to those who lost more than they thought they could bear, take heart, because you survived to fight another day.
Above all, remember that God is good and trials are there to strengthen us.
Very nice ... thanks for sharing.
Happy New Year, to you and yours, GOPJ!
I’m going to start because. Cold to the bone, here.
Although this may be the last winter for them all as they are about ** years old...
Awww...
Thanks, Chode! Very cute!
Happy New Year to you and yours!
Ah yes, but always remember that this year will be seen with 2020 in hindsight.
Thank Heaven for small favors! I, for one, will find it a vast relief to put that year behind me — like in the rear view mirror, getting smaller the longer I drive...
I hope everything is good for you and yours, Rob’t!
A very good year to you gentlemen. Great cat video!
Speaking of cats, we’re back from church, and I’m going to find a cat and have a nap.
thx, and to you and yours!
You and Jake have a good Nap-With-Cats time, and I’ll see you tomorrow.
Of course, just about the time I head down the hall, folks will turn up in droves to wish a Happy New Year all around...
Have a good night.
Not a bad start; it’s been Friday all year!
Excellent point.
if only it could stay that way
So far, so good.
Thanks! I did.
But it has a drawback, and I will now (in the next few weeks) try to remedy it. I fell asleep at 1700 slightly awakened enough to roll over and then went back to sleep until just before midnight. *sigh* I’m not sure if I like this, but it means, I think, that my sleep patterns are finally back to what they were before CFIDS came to stay.
Maybe by the time I get settled in AR, my sleep habits will be readjusted. Somewhat! ;o]
