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 hope you have a very nice nap. I’ll be off for my colonoscopy with my minder, Pat, in just a few minutes.
Good morning. Happy Monday!
Beware the ides of March. Although I find the ides of April much more concerning.
w00t!
Thanks! I would have felt guilty but I was just way too tired.
I’ll let the next eight or 10 go, if I can... ;o]
Happy Monday. Stay out of the Senate.
Prayers up for your procedure. I hope the grogginess isn’t too profound when you get finished!
I don’t have sedation. I will just listen to a podcast and do labor breathing.
Not an issue. SOMEbody has to do it.
All done. No polyps this time. Pat will drive me home in about 15 minutes.
And now I’m home, about to go to bed for a while. Maybe a cat will turn up.
Sorry, kids, but I have the major S-l-o-w-s today. I got the bed made and now I’m plumb tuckered out. I had a couple of packing jobs outlined for today, but I think I’ll have to pass on them.
Also, today’s Apathy Lecture has been cancelled for lack of interest.
Maybe I’ll feel better after I have some lunch, but I think the day will be short for me. There is another snain storm due in tonight, so the wind chimes are announcing it’s arrival.
I need to get the S-l-o-w-s over with by tomorrow AM because Walmart beckons...
Bed is what I would have suggested for you, because Procedure. They always knock the wind out of your sails for a while.
I hope you feel better when you wake up, and I’m happy to hear there are no polyps.
It’s Daylight Savings Time.
Who can stop this mad cycle of changing the clocks twice a year?
Congress??? Congress has to do that?
We’re sunk.
DST gets harder for me to handle each year. I don’t know why it wasn’t abolished 50 years ago. How can anybody be making any money on this, unless it’s people who profit from Death Due to DST?
Afternoon, Moose07.
Finished with nap. Tea, anyone?
Tea?
What a wonderful idea.
Afternoon TC.
:)
I think I’ll have another. I have a headache from almost two days with no food, but it will get better. I won’t need another colonoscopy for five years.
Take it steady on your first meal.
However Tea fixes everything.
Garlic is a panacea, too. Maybe some garlic for the headache, and then more tea.
