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.

Maybe they were traveling from A to B on the cheap.
We had a nice day in Chapel Hill. Big gardens, great flowers, trees, then we walked around the UNC campus a bit and went to their little art museum. It had a frw Greek and Roman pieces as well as miscellaneous paintings, old and new.
Good morning.
That could be. We knew a couple from The Netherlands who were traveling the US of A on $6 a day in a VW bus. They brought a big box of little wooden shoes which she painted and sold whenever they needed extra money.
Museums are amazing places!
Good morning. I’m waiting on coffee. Today, we will go to the state history and science museums. I think they open at 10, so we have plenty of time to eat and get squared away.
I think it rained a bit around 4 am. At least it sounded like it and I got up and closed the tent windows.
Good morning. Another camping cat photo until the master of the morning kittehs can return.
Good morning, kitteh. James said it didn’t rain, and he would know: he’s sleeping in a hammock.
A large group is moving in to all the vacant campsites. Lots of Scout age kids, but a campout starting Thursday morning is unusual in our experience.
Kitteh is saying, “Is she back, yet??”
Good morning, both of you!
And thanks for the kitteh, ArGee.
Maybe what you heard during the night and thought was rain was something I’d rather not think about.
It might be a church youth group that moved into all the vacant campsites.
Or maybe some people trying to get away from protests/riots.
I can see a day in my future when I want to eschew “civilization” so I can continue to live free.
I know what that’s like!
Well, two more boxes packed, and some organization of others that were already packed, and I should have known better. But someone has to do it.
Tomorrow, with any luck, I’ll get more books packed. There are also some things in the kitchen that need to be taken care of so when I’m done with one, I can owrk on another.
In the meantime, I can’t help but wish I were camping somewhere... ;o])
Very nice time at museums. We got misoriented on the way back to the state park.
It looks like the group that arrived this morning was just a day activity. They’re all gone now.
Ginosage, now in cat form.
I think this will be the last camping kitteh post.
Good happy Friday camping kitteh morning!
I was busy writing letters. Now the sun is getting ready to come up, while the moon is shining brightly.
I just walked over to mail the outgoing and collect the incoming stuff. An ad from AARP, which I will NEVER join, and a DVD of the Apollo 1 mission, which gave NASA the incentive to not give up. (NOVA-pbs production)
Since I also packed yesterday, as well as on Wednesday, I’m going to sit today out. I just don’t want to push my luck.
I hate went I get misoriented while driving! It’s bad enough to do it at home!
If Ace hardware ever re-opens at 0700, it will make my life easier! This morning I’m going to get a couple of mailbox keys made.
Good afternoon, EDT. We are home. All the pets are alive. Laundry is on. Vlad has taken a much-needed shower.
Awww, nice kittehs.
Well, it’s almost afternoon, MDT, so close is good.
Welcome home. The small thing has been delivered. Is Shannon upset with you for being gone?
It’s going to be very nice today, in the 90’s, but by Tuesday, it will be back down to 70°. I may have to turn on the fan in the bedroom. The place for the fan in here has been taken over by things that have been packed up.
*tagline*
Thank you.
