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.

The mulberry trees were and are the worst offenders, and second to them were the Russian olive trees. Now, both are forbidden to be brought in, planted or re-propagated in any way.
Here, it’s the ragweed that’s killing me!
W00t!
For several reasons, Chode! Good to see you again! :o]
Yeah. I can relate to that!
;o])
Happy Easter, y’all!
Happy Easter!

Floofy ambush in 3...2...
Good morning.
The laundry is done and hanging to dry, the bed is made and the allergy pills are not really good for 24 hours. The eye drops aren’t good for four hours, either, but my body is good for nothing.
If I thought I could lie down and then wake up with the allergies behind me, I’d do it in a heartbeat. </whine
I’m sorry you’re feeling so bad. Because I am so fortunate in my health, I usually can’t say, “I know how you feel,” but I’ve been through some allergy episodes where I was ready to die and took so many antihistimines that I’m lucky I didn’t.
So I know how you feel, at least on the allergy front, and I hope you start feeling better soon. Maybe you’ll get a few days of cold rain!
Thanks! I appreciate that.
I’ve tried to stay busy so I don’t think about it, but it’s wearing me down. I emailed my doctor, so I may get a text from Walgreen’s later today about a prescription that’s better than the OTC stuff I’ve been taking.
This is hard for me, because I’ve never been bothered with allergies. We had mulberry trees all over the property in Henderson and the most I got was a few sniffles. So its the ash and the alder that are at fault. This is affecting more parts of me that I care to explain. Of course, this makes me appreciate my kids more, because of their severe allergies. Ones they’ve had to deal with every year since the onset of puberty. I’ve been spoiled and I don’t like being lumped with the masses in the allergy department!
So I’m going to go lie down for a bit and hope I fee better when I wake up. I opened the doors to let in the cool air, but as soon as the sun is up, they’re going to be shut tight. I wish chicken soup was good for allergies...
We’ll be going out pretty soon. I’ll take picture at the garden. Tom told Chipotle he’s sick today. Soon he’ll be telling them he quits.
We said we will cover a month’s rent for him if he needs to concentrate on school for the remainder of the semester and then get a new job once school is out.
Tom needs to do what’s best for Tom and if a day of “sick” will help him decide, then that’s what he needs to do.
Good for you to back him up! <3
Here. Reporting for duty. I hope everyone who wanted to had a Happy Easter and the rest had a good weekend.
Happy Monday.
Backatcha.
Sorry to be such a party pooper but allergies are beating me up. I’m off to bed. See ya tomorrow. Have a good night!
Turns out the botanical garden was closed today, so we went to the county park not to far from there and had a nice, outdoor walk.
When we got home, I took a nap. Tom has gone home. He mentioned having a quiz tomorrow, and he’ll need to decide about giving his notice at Chipotle.
I understand about allergies. I had to blow my nose again just now, and now I’m out of TNT.
What did I miss about Tom and Chipotle?
Oh, he’s been working there for a couple of years, and liking it less and less. Most recently, he was promoted to “service manager,” but they still want to pay him less than Pat is making as a stocker at Walmart, and the rep from Corporate said that Tom’s even wanting to discuss being paid a market wage was “a bad sign.”
The store where he works keeps losing employees, so the remaining ones work harder and longer - but never overtime! - and finals are coming up. He could find a new job this week and then quit, but he’s applied for some summer jobs in his field of study - saving river and mountains - so he doesn’t want to take another restaurant job or retail job right now.
DP and I agreed that he can quit Chipotle if that would give him time to work harder at school for the next six weeks, and we’ll pay his May rent. (Maybe June, too, but I didn’t offer that up front.) If he doesn’t get one of the environmental jobs, he can get a regular job when the semester is over.
Thanks!
It’s not necessarily my nose, except for the sneezing, and the constant drainage, but it’s my eyes and the coughing. And the over all feeling of malaise.
But the prescriptions I’ll pick up today should help. If not, I have to go in for a Kenalog shot. I may have to get used to that, depending on what allergies I have to face in AR.
