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.

Good Happy Monday morning, ArGee.
I hope your weekend was a pleasant one. We had snow in some places, here. At least, that’s the word on one of the FB Groups.
Are you still growing mushrooms? Just checking!
For whatever reason, the laptop keeps running slow or locking up every morning, and it just did it again.
Must be Monday.
We had temps in the 70s here. We went to the in-laws and put steaks and hot dogs in their grill yesterday.
No new seizures for the week so I breathed a sigh of relief yesterday.
Any pattern as to what you’re doing when the laptop starts lugging or freezes?
I think sometimes these new WebSite capabilities take the latest and greatest power in laptops.
Could it be that I have more than three windows open? Or more than two? This time, it froze when I was in the middle of a PM with my son. There seems to be no other consistent criteria than having more than two windows open. Or the time of day.
It depends on what the windows are or what the power of your laptop is. I have a fairly recent generation machine but if I’m running our meeting system with video it lags. And I think some ads on some web pages do that to it, too.
FR, FB or MeWe, (and maybe now, Parler, since most of FB is heading there) and Yahoo mail, which window I usually use for a miscellaneous search window. I’m in the process of sending most of my FB contacts to MeWe. Maybe I’ll have to send them to Parler, as well.
I haven’t checked on the mushrooms in the last few days. I’m planning to plant the mycelium mass out in the garden, once the weeding is done.
This morning, I pruned the holly trees in addition to quite a bit of other stuff. Next will be a Pat Driving Adventure.
The bed is made and after this dose of pills I might get something done. This is probably Monday, from the looks of things.
I actually work in a mushroom patch.
I used to work in a mushroom patch. It was called a cubicle and it was so small that the chair faced out and I had to back in. Yep. Right next to the supervisor’s desk... ;o]
Cheated Death Again!
You’d better hope Death isn’t planning retaliation.
I think Death is playing the long game.
I hear that phrase but it has no meaning for me. So in lieu of asking for an explanation, I’ll ask you to forgive my exit to bed!
Ta!
Best wishes for a swell Tuesday!
I got a lot of yardwork done today. I will hurt tomorrow.
It’s 32° and feels like 27°. I’m not looking forward to my freezing trip to Walmart but, water.
Good morning. It is warm here.
Another sweet face to start my day! Thanks!
Good morning.
The pills have been sorted and I start another round of tea this morning, and I’m hoping the next six months will be that last six months. It’s an expensive necessity!
I awoke in a panic in the middle of the night, thinking today was the day I had to go in to the ophthalmologist but then I remembered: that’s Wednesday!
Now I need to go get the sleep shirts and get them off the hangers to be folded when I get back from Walmart. I’ll make the bed while I’m in there.
