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 can’t wear them though
They’re a high wedge heel boot.
I’d fall off them.
:D
Forgot a lotta stuff from back then...
Buried deep in the sands of time.
I should never have gone to that site. Now I’ll be dreaming of all those beautiful “wedding shoes!”
Wedge heels are not pretty. I don’t think so, anyway.
They probably wouldn’t dare look for you in Columbia. I’ve always wanted to go there for the emeralds. ;o]
Colombia has beautiful birds and flowers, too.
ooohhh...lookie! Two floofs! Now, I’m going to go shower!
Good morning. Enjoy!
Good morning!
I’m back. The shower was OK but I was too tired to enjoy it.
The video camera on my laptop doesn’t work, so I could see the moderator of the meeting, but he couldn’t see me. I don’t know how to fix it, but I think it may be the firewall in this thing.
I have an appointment at the pain clinic this morning, but it’s not until 0915, which is about an hour later than I wanted it, but there we are.
We have a warming trend for the next five days, but I don’t know if we’ll still have “winter” after that. I hope I don’t move in the middle of an AR summer...
Good morning. Happy Wednesday.
It finally stopped snowing. We may have to move cars again. They seem to have actually tried to clear half the parking lot last night.
Good morning again to all. Cold here - a little ice on the birdbaths and the puddles - but no snow. My mom said my brother in Scranton is hip-deep in it.
Heh-heh! I love Calvin!
Good Happy Hump Day! Hurricane cleans the major roads and the wider streets, but it’s a while before they get to the smaller side streets. Of course, there hasn’t been a good snow here for several years, so...
Ta-DAH! The Package Bunneh is on his way to your house this morning! Tell the cats to be polite when he shows up, please. ;o]
Looking forward to that bunneh. It’ll be just like Christmas again!
Do you ever feel as though your life is on a loop? Someone from church asked me about the students in my bilingual sacrament class in 2016, so I got my journal out of the closet to see if I’d made any useful notes (I had), and the majority of the entries could have been written this year.
I like the Package Bunneh, too! All I can think of is that someone cares! Usually, it’s me, but still... ;o]
Yes. I realize quite often that what I’m doing at this moment is the same thing, with few variations, as what I did last year at this time, or three years ago. It all begins to run together in a massive blur. Rather like Darks’ molasses miasma.
As Jonah Goldberg says, “Time is a flat circle.”
Ah. Like Planet Erff.
One of my asthma inhalers is defective, so I’ll take it with me today to see if I can get the pharmacy to replace it. What a burn.
