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.

James cheered up once they got outside. We didn’t many mushrooms. I guess it hasn’t been warm enough since the rain.
I think it’s for the same reason cats make an effort to sit on any piece of paper on the ground: if it’s there, it must be important to you, and that means the cat is in the way, and that means the cat is better than you.
But yes, the cats are much better than we are!
James has always liked outside. It’s the “getting there” that he seems to balk at. I had a kid like that...she lives in CO now. ;o]
For our next thing, I’ll take James to Walmart. They need new shoes again.
You might be onto something the 'researchers' didn't consider in their conclusion.
Only nine of the thirty cats sat in the designated square and then no longer than 3 seconds.
One might conclude that 21 cats thought the tape was just a stupid human thing to do.
There is a strong possibilty the nine sitting cats are elite recon cats scouting anomalous human behavior and reporting telepathically to Cat Mothership Intel HQ. Three second squat told them all they needed to know. No report if any of the nine returned to the illisionary squares after the trial observation.
Have to wonder how the grant application read and how much was requested to finance SCIENCE.
I just went to the library. I think I’ve nearly exhausted all their stash of NOVA-pbs movies.
In a few minutes, I’ll go in and get the winter clothes put away and then go back in a while after that for the stuff I need to keep for future reference. Two items are dresses that were made in Pakistan that need to be shortened, and two are silk “thobes” that Igor had had made while he was in Saudi Arabia in the 70s. One was for me and one was for him. So mine will go to FD and his will go to FS.
I can’t do it all at the same time today. My back is protesting, even on what little I’ve done. Walgreen’s is still fighting itself over the prescriptions that went out yesterday, and I have to wait for the first one to drop off. The second on has more tablets, so I can get this packing underway.
Yes, Favorite Son went through a new pair of shoes every six months or less for about three years. He never grew “up” in those years, but when his feet stopped growing, he started and he was in the army almost two years (enlisted at 17) before he finally stopped at his current height. (6’4”)
And if it helps, PV was his cat, but when he was out of the house and on his own, he had a cat named Beaker, and his buddy had one named Tex that used to visit, on his own. Just show up at the door, wanting to come in and get loved.
They didn’t have any shoes in James’s size. We’ll have to use the website. They had socks for Vlad, though, so it’s something.
Not a surprise there. Some children will sit or stand in a circle or square on the ground, just because it's there.
Hoo boy. Done in the bedroom, but the storage bags I had been using for the last 10 years finally wore out — cracks and tears. I didn’t want to order more, but I had to before I try to make this move. I’m not going to use a box for the clothes and I don’t want to buy another storage tub.
Some days, as tiamat used to say, it doesn’t pay to chew through the straps.
Don't know who tiamat is, but I'm stealing that.
;>)
I had a bit of a nap. Now I’m back, getting ready to chop vegetables.
Tiamat was a poster from the original Undead Thread, from 2004. She passed away in probably 2006, either when I had just moved from Tucson to Vegas, or in 2007 when I had moved from Vegas to Henderson.
She had a wicked sense of humor, and I don’t think I knew a FReeper who didn’t like her.
Naps are good things to have, I hear. One thing I also heard was that they improve one’s memory.
If I could only figure out when to schedule them...
Ok...that explains why the name sounded familiar...thanks
:o])
1:00-ish is when I try to get a nap.
It’s clouding up again here. If it doesn’t get warmer, we won’t see a lot of good mushrooms!
I seem to do better if I take a nap in the morning, but now, with me trying to get my schedule switched around, a nap might be better had at noon or earlier. My mother always took hers at 1230, but I don’t recall how long she slept. Probably only an hour, but I never knew her to NOT take one.
The barometer is dropping here again, and the Adm. Fitz is getting lots of pretty crystals. I don’t need either of them to tell me what my body already knows.
Your mother had lots of years with babies, like me.
I’ve cut up vegetables for the dinner. Maybe I’ll go watch a lectures and write a letter next.
