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 found one on Amazon, but I dunno. I want it, it would help me get my voice back in shape, but I’ll have to think about it a little more.
Under $50.
Maybe after you move. DP got an electronic one that folds up to about shoe-box size.
Wow. I woke up crying. I had dreamed of the graves of small children.
Oddly enough, it portends a “legacy,” whatever that means.
Now I’m going to go shower and see if it improves my disposition.
Oh, that’s unpleasant. I hope the shower helps!
Beautiful cats!
Thanks! It did!
Why you not feed mes?
Good morning.
The Floofs are beautiful!
I have to go make some tea, but I’ll be back before you can miss me!
Thank you. They are rescue/foster kittens in Australia.
How are you today?
I had to feed catz here, too. Shannon is on the kitchen mat waiting for her meat and her thyroid pill.
How is she doing on her Thyroid threatment?
She looks much healthier. She’ll go for another blood test in about 2 weeks.
She was happy when we had the sunny days for lurking in the garden.
I bet the sun felt good on her old kitty bones. I hope the blood test shows improvement.
I’m sure it will, based on how well she looks compared to a month ago.
I got a couple of texts from Favorite Daughter after I was asleep. She and The Guy had the second installment of the Covid vax.
“Wow. the second vaccine got both of us really really sick. I just up an hour ago [1600) from a nap I took at 1000.”
[45 minutes later] “I’m feeling sharp electrical stabbing pains all over my neck arms and legs.”
This does not sound good.
I will keep her in my thoughts.
Thanks.
I suggested she not do it, but she’s a follower at heart. A lifetime of following everyone but the mom who loves her more than anyone else.
All I can do is wait to see how it turns out.
I hope it works out. They say the second dose can be difficult for those who already had the disease.
I am well.
Having a little get together this evening.
having a great time with my new (to me ) English Shepherd Gracie

How is life with you?
All good?
