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.

It’s 38° and the wind 9 mph out of the NE, and I really do want to be warm again.
Thank you and good morning.
I got my replacement SS card in July of last year. They have a date of issue on them, now. I’ll just keep them both for now.
G’orning, y’all.
Good morning to you, Sg. I hope you’re feeling well today.
Social Security is an oxymoron.
Firefox does all the work. So if Firefox is running, the streamed video should run.
Firefox is no longer running. It was slowing down too many other programs, so I’m hoping that things will be a little easier to do, now. I just have to bone up on Linux and get it installed.
It absolutely is. And was a stupid idea that falls into the “If It Ain’t Broke, Don’t Fix It Category.”
The politician motto is “If it ain’t broke then what will I run for re-election on? I better do something anyway.”
You’re welcome and g’dafternoon. Or buenas tardes.
We’re all very involved with entering all our Envirothon information into “Quizlet” for online flash cards. It has to be done by Friday.
After blowing through that red light (at 37 mph) I wasn’t much in the mood for anything else.
I’d like to stay home today, but I have errands to run again. Darn it.
And I lost my mailbox key again. I hate with this happens. That’s twice now since I’ve moved here, and I’ve NEVER lost my mailbox key, no matter where I’ve lived. I lost it between the office and home. Maybe a football field’s length. Mostly on pavement. Go figger.
I wouldn’t mind a day of catball myself, but duty calls.
I’d like a day of catball with a real cat.
Meanwhile, back at the ranch, I’m going to confine my activities to next to nothing to avoid a repeat of the last two days. At least until I have to head out the door.
I’ll wait for you to pop your head up for a breath of fresh air. Then I’ll wave at you again. ;o]
Good morning. Happy Friday Eve. It is also Maundy Thursday. I don’t remember what that means, but I remember that it is. So happy Maundy Thursday.
“Maundy Thursday” is the day of the Last Supper. The designation “Maundy” is from early modern English, from the same root as “mandate” and “commandment.” The term attaches to “Holy Thursday,” as the Catholics say, because at the Last Supper, Jesus said, “A new commandment I give you: love one another as I have loved you.”
I’ve been distracted by emailing my mother and some other issues, but I’ll be buckled down to “Forestry Key Concept 4” by 9:00.
Thank you for the English and History lesson. I always thought it was because it felt sort of like a Monday given what we knew was coming. But that’s a kid’s mind for you.
I remember the term from my days in Catholic school, though nothing more than it was the day before Good Friday. My younger sister gave up watermelon for Lent the year she was six. Or maybe seven. Pretty funny, since we lived in Central Utah at the time, when snow was usually still on the ground, or at least on the foothills.
