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.

Unnngh. It is that time of year for you. The Wall Street Journal was mentioning “long-overdue rain” and like that in the Southwest.
Yes, the rain constitutes the “winter” here. I think I’d rather see snow, but I’ll have to get used to the rain because AR has a lot of it. And it’s very cold in the winter, as well.
Probably not as cold as you’re used to, or as hot, but more rain. Maybe you’ll like it. Iirc, you haven’t lived east of the Rockies for a very long time.
I have Shannon her pill wrapped in a bit of meat. It’s a tiny pill, fortunately. Now she’s sitting in the kitchen waiting for more meat!
From what I’ve seen this winter, Cabot is much colder than here, but I think that has to do with the amount of humidity in the air all the time. I was in Del Rio from 2002 to 2004, and though it was mild, it was humid. MO was very cold, with horrendous winters.
I hope the pills help Shannon. Now, I’m going to go to Lin’s. BRB!
I’ll be going to Walmart shortly. Of course, I do everything “shortly,” heh heh, I crack myself up sometimes.
You crack me, up, too! LOL!
Back from Walmart. It was strange being in a store after two weeks!
Pat discovered that he needs a doctor’s note to go back to work. He’s taking his form over to the clinic where he was tested, so they can sign off on it. Sure is nice that he can drive!
It’s always strange to go back to a place you make several trips a week to after a semi-prolonged absence.
When I got to Lin’s the parking lot was empty except for the employee’s cars. When I walked out the door to come home, there must have been 20 cars and counting! Eerie!
Lin’s has a humongous section of their own spice blends and rubs, and this morning, I found one for rosemary-garlic, and thought how wonderful that would taste on roast chicken. They also have one for poultry called “cranberry-herb” rub. There’s a harvest blend seasoning (I think it’s like “Season-all,”) and “Cattlemen’s Ranch” seasoning. And a dozen more. Exciting flavor blends for a cook. The first time I saw them, I thought of Tom. I could pick some and send them if you think he would use them. Or you would... Or maybe even DP or Vlad! Just’ sayin’...
Yes, it IS nice that Pat can drive, now and can run his own errands and fend for himself in certain situations. Another few jobs that Pat’s mom doesn’t have to worry about trying to schedule in.
That’s handled. He can go to work tomorrow. Now he’s going to Arby’s to buy himself some lunch, after lectures on which way to go to avoid bad outcomes on US74.
DP and Tom are buying spices at Great Asia Market!
Ah. Good for Pat!
As for Tom and DP, if they decide they want to try some Wild West Flavors, let me know! They’re not expensive but they certainly taste like it!
The sun is trying to shine and I’m trying to stay awake. It smelled so fresh out when I went to Lin’s this morning, and it’s supposed to be all clabbered over again tonight and tomorrow,
I fell asleep, but I’m back. It will be nice when Tom can come over. Maybe next weekend.
Just before I fell asleep I had this horrible thought — in all that talk about ink for the printer and printing up a copy of the application, I didn’t print up a copy of the application. I mentally did a face-palm. That’s the very first time I forgot to keep a copy of the application, and I hope this is one time when it won’t be necessary.
But the application is well on it’s way to AR and if I’m lucky, she’ll have it by Wednesday.
It will be fine.
And look! A Baby Wednesday to make me feel better!!
Good morning.
Because FB crashes my laptop, I have to visit it early in the morning to let my relatives know I’m still alive. I only have time to see responses and check the feed and then I have to get off of it.
It’s debatable if I will go to church or not, but at the moment, I’m leaning towards going. We’ll see how I feel in a couple of hours. I feel like I need to make the effort, anyway. But I can always watch it online even though it’s not quite the same.
Sounds like it’s a sign that Facebook is bad for you!
The blue jays have arrived at the feeders. Five, at the moment, but I’ve seen as many as seven, including one with no tail feathers that flies like a shoe. They are really large, at least half again as big as Tom the Mocker.
I’m going to have a shower, but first, I’ll give Shannon her pill.
FB is the only way I have at the moment of keeping in touch with the nieces and nephews who care about me. The ones who don’t care are obvious by their willingness to find fault with what I say. I’m not talking about discussions; I’m talking about animosity and contention.
But it’s definitely an overload for the laptop!
I have to limit my time to 45 minutes maximum. I used to leave it minimized, but I can’t do that, any more because FR does almost the same thing. I can’t have both of them running.
Which makes me wonder how people can have FB on their phones.
There was a blue jay when we lived on Douglass Island in Alaska who learned very quickly that we had food set out for the chipmunk that liked to come up onto the porch. Dad had made a little platform feeder so we could see it from the kitchen window. The jay would perch in one of the fir trees and wait for the chipmunk, then swoop down, scare the chipmunk off and help himself to the food. The food would be there, but the jay would wait.
Regular visits from blue jays are a new thing for us this winter.
