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 imagessimilar 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 was a little surprised to learn about the level of deer population and hunting in Germany. I guess it’s like Pennsylvania ... restored forest land and wild herbivore population.
Thanks.
I was worried about her, what with her other health problems.
It was 29° when I went over to wash clothes, but at least the wind has died. How long that will last is anyone’s guess. The barometer says it will be sunny today. The Fitz says more wind is on the way.
She’s been fine. Next Monday will officially be 3 months without a seizure. Yesterday she managed to eat an entire (smallish) rawhide in an hour or so, which surprised Mrs. ArGee no end. I hope it doesn’t upset her digestive system.
It was 37 this morning when I walked the puppy. I don’t know if spring is on the way or if we have more cold coming. I’d almost rather not look.
I agree: I’m not going to look!
When I was studying to be a vet tech, we were taught that rawhide chews had a tendency to block or perforate the intestinal walls, but maybe they changed their minds on that, since medicine is an inexact science. It’s obvious to me that the puppies like the flavor and texture. I hope she has no problems with it for sure.
There are definitely green things on the trees at the library, though there is still snow on Pine Valley Mountain.
I’m just very tired of being cold.
It is not cold here today. This is a great improvement.
I’m so glad! I hate hearing how cold you are because I’m far too familiar with the feeling!
I’m wearing fewer layers than usual!
Jake was out all night, a development long overdue. Conveniently, he came in and went to bed before the rain started again.
They are recommended for supervised chewing. Mrs. ArGee just thought she had a little more time before paying that close attention.
The pup is big, the chew was small, so hopefully it will all work out.
That last was for you, Nully.
That’s good then! I’m glad to hear things have changed in the medical world in the favor of the animals! :o])
Congratulations on less layers! I seem to be wearing more, these days. Especially Mondays, when I’m out so early.
Good for Jake. He probably really kicked up his heels while he was out!
And ... the puppy is in heat. And we didn’t have any puppy diapers already handy. So far there hasn’t been much getting past her diligent licking.
Oh, poor puppy!
I’m back. I talked to our music director about where we were regarding Covid restrictions, and he said, “I’m just so over this ****. Do what ever you want but try not to be too dramatic about it!”
I think that means we could have all our choir ladies except the very elderly.
I think the entire country is feeling the same way!
I noticed half the people in church yesterday were wearing their masks wrong, some just had it over their ears as a token of obedience.
Six months from now, the signs will still be up but the masks will be mostly left elsewhere, to be produced if questioned.
One habit I picked up while in NYC was to sneeze into my elbow or my shoulder instead of my hand. I will pull my jacket open if possible. That reduces the germs that get spread by sneezing and using that same hand to grab a subway pole.
I have kept that habit. I think the masks can all go and people can learn to sneeze into their elbows or shoulders. Some people will still get COVID, but that will be true forever.
I sneeze into my arm if possible.
Honestly, it seems like the subway would be a good place to continue using a mask. Out in the woods, not so much.
