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.

-00 to you!
Problim iz no mous. Needz mous.
Happy Friday!
w00t!
I hope the winter doldrums aren’t being too hard on you.
Whoa. Oops. Sorry...someone else should have had it.
Mouses is good for kittehs.
Happy Friday to you, too!
And how is puppy this week? You haven’t mentioned her, so I’m thinking things are going good.
Thanks.
Winters are always hard, but I’ve learned to dress in layers for the most part. The lack of sunlight is a real killer, but I can’t find a lamp I can afford. Maybe some day. ;o]
Yes, I’m going to weekly updates on the puppy since we’ve been more than 5 weeks without a seizure. If we get to Feb 8 I’ll go to monthly.
In any case, all is good. She’s a bit rambunctious still. I’m wondering if that has to do with waiting to spay her. We’ve never gone past 6 months before. But the new “standard” is to wait for the first heat. I’m not sure if we can wait that long.
In Las Vegas Valley, the consensus is to spay them at about four months of age, and not wait for the first heat. It seems their thinking on it is it’s more damaging emotionally to the pet.
I waited for a first heat on Hobbes before taking her in, but after almost three weeks, she wasn’t actually over it, and the vet was extremely surprised. So was I. At that moment, I had to toss everything I learned in Veterinary Office Assistant classes about spaying and neutering.
In this case, for what it’s worth, I think you should do what YOU think is best.
Happy Friday, ArGee.
We got a phone fall from Elen, USMC, who found out from Drama Queen who found out from Patrick that we are infected. I’m superindustrially furious with Patrick, but I’ll get over it if he gets himself squared away to start Shakespeare by 9:00 a.m. EST.
Anyway, Elen is fine, except for boredom. She’s had one dose of a two-dose vaccine, which is nice. She didn’t get her book yet.
Oh, now I get it!
LOL!!
Humor is not my strong point.
It’s OK, T-c! I must say that at times, your humor is positively brilliant! Mostly because of your timing. Most of my humor has been dulled by years of depression and abuse, but your humor is there when it’s needed. I love to see the interplay when you and Bob, Darks, Moose and a few others start in.
I miss the days when I was like that, and I wish I could contribute, but it’s fun to watch.
:o])
Thank you.
We just read Henry VI, Act I, Scene 1, and now I need to work on my genealogies some more, because there are some people that I can’t figure out how they’re related to the others, especially the French.
And here am I, sitting on the genealogies of the Royalty... may I be of assistance?
;o]
I think we can find everything on Wikipedia.
No doubt!
Our Colton kitty will touch the tablet with his paw and change movies on you if he doesn’t like what is on.
“Patrick...half right face, front leaning rest position, destroy yourself. One, two, three, zero one! one, two, three, zero two...”(eventually) “one, two, three, three zero one!”
Above pushup position with command “destroy yourself” in 1996 meant you were doing pushups until you splatted against the ground.
Picky!
