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 imagessimilar 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.

If I could get work done while unconscious... I would be the ruler of the known Universe, Padasha Emperor Shaddam the First...
She was older than the Age of Consent... By a few million years...
Great! They have a full set now.
Sixteen years? No way.
It works for cats.
Shai *meow* Hulud...
Way...
I can’t get out of this sock.
There is a reason for occupying the sock. It’s a cat thing...
So I am told by those with opinions on such things.
I don’t argue with cats about their reasons.
Hi, Rob’t!
Have you tried cold coffee? I prefer the stuff, so much in fact that I don’t even drink any hot drinks. Coffee has to have a chocolate creamer in it, though! ;o]
It might change up your night shift, is all I’m sayin’...
Yessim. I believe it was June of 2004 when j_jfate met his Betters and we began paving process to the End of the Internet. And here we are. I believe Bob has the chronology of threads on his home page. ;o]
LOL!! Cute!
Hmmmn.
We have met the enmity of the universe (er, Internet), and it is us.
Yes, indeedy! Who else? ;o]
Morning kitteh looks sad, even though it’s Friday Eve.
Good morning.
I slept well last night and tried to sleep through the alarm this morning. I woke up during a dream of receiving a diamond ring in the most beautiful gold setting. But since I can afford neither the diamonds nor the gold, it was a good omen. :o]
If anything, I’m more tired this morning than I was yesterday, but I have Things To Do and I promised Me that I would get them done today. Period.
So I’ll start in just a while and be done within an hour because that will put me at my limit for the day.
I think kitteh is concerned about plate tectonics.
Good morning! Jake must have gone out when Pat got home from work, because he was at the door this morning in a snit. Now he has gone to bed with his purple plush dinglebob blanket.
I found a website for Kathleen to do math drills, so I’ll have to turn over my computer shortly!
Meownin’.
Happy Friday Eve!
