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.

Anyway, maybe C&H can cheer you up.
Thanks! I should just drag out his books on days like this.
It’s not that I need “cheering up.” It’s that I need the depression to lift. Not the depression “mood,” but the depression of having my joints and muscles “pressed” in a vice.
I’ve been like this since I was a kid, which is why I chose the desert to live when I had the choice — the sunny days kept this kind of thing to a minimum.
Anyway, I apologize if I seem all Doom and Gloom. When the clouds disappear, the depression on my body should go with them. Thanks for cherking me up, though! :o])
We just went to Mass. Now it’s lunch time, and we’ll get everyone’s Envirothon review assignments sorted out before naptime.
The rain stopped.
Well, Mass is a nice thing. Cheery, even. Even better if the rain has stopped.
The chicken was a wash. It had an “off” flavor about it but not on the spoiled side. It tasted more like mold. So the whole thing will be going out to the dumpster when it’s cooled sufficiently. *sigh*
That’s a real nuisance!
And yes, it was nice to see some non-family personnel.
Yes, it is a nuisance. I’m just about done with this day, but I need to hang in for another two hours. It’s too early to quit!
Maybe I’ll wake up in the morning to find a sunny day ahead, and I won’t be so crabby. Crabby is not a good way to keep friends.
No problem.
Cherking people up is my specialty!
I don’t know. Lucy van Pelt always had friends.
I’ll be your friend no matter what.
I couldn’t have asked for two better friends! Thanks, guys!
Now, to avoid any more crabbiness on my part for this day, I’m finally going to toss in the sponge and head down the hall. “Tomorrow’s another day, and if it ain’t, it don’t make a darn bit o’ difference!” So said my wise ol’ ma.
Have a good night, both of you, please! :o])
I’ll leave the good night for you.
Well, it sorta was. At least three solid hours of it. Maybe one day, the sleep patterns will get back to normal. Maybe. Or not. Still, I’m grateful for what I get! :o]
Better than a poke in a eye with a sharp stick, as my late father would say.
(singing)
You just call out my name
And you know wherever I am
(/singing)
While hard to argue with, it’s hard to see how that was the most reasonable alternative.
Cheer up, kitteh. It’s Friday!
Happy Friday, everyone!
I have wondered why Dad thought a poke in the eye with a sharp stick was an expected outcome, but it remains a mystery.
I’m off to the podiatrist. Happy Friday!
The rain started and stopped again. Cats have already given up on the day.
Yes, the late Igor used that phrase, as well. Until he came along I had never heard of it. He was from OK, so I wonder if it’s a regional thing.
But I’ll take whatever sleep I can get and like it!
Such a tiny little breakfast marmalade floof!
Good morning.
I slept in until 0304, and that meant getting started was difficult. But. The shower has been had, the bed is made, prayers have been said, and the letter to Charlie has been written and is waiting to go into the envelope.
The library sent me two notices of DVDs that are ready to be picked up, but I’ll wait until tomorrow, just to see if any of the other two show up between now and then. I hate picking some up only to have another come in as soon as I’ve left the library.
Unless, of course, I find out that the thrift shop is open for donations, and then I’ll go to the library, anyway.
It’s rainy again, and I guess, if I were a working stiff, I would see rain on Friday as something of a deterrent on good times that night, but since I have no social life, well...the rain is just depressing. However, since it’s good for growing things, including humans, I’ll take it.
So Happy Friday, which means, Happy Weekend Eve!
