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.

I thought they must be, as I don’t recall you mentioning them last winter. Only the mockers and the cardinals. And the occasional soon-to-be-dead bunny.
And the wrens and finches and bluebirds and tufted titmice and dark-eyed juncos and woodpeckers and chickadees and goldfinches and brown thrashers and starlings and ravens and the occasional confused hawk.
But the blue jays are new. It will be interesting to see whether they try to nest here in the mockers’ territory.
The mockers are extremely territorial, so I’m surprised at the amounts and varieties of birds in your back yard. But it will be interesting to find out of the mockers prevail or if the jays get to move into a new neighborhood.
In our subdivision most sections of 2-3 houses in a row have either mockers or blue jays resident, but not both. During nesting season, the mockers chase all the other birds away a couple times a day, as well as harassing the people and the cats!
This appears to be a takeover attempt by the jays, but it’s too early to see whether it’s just the food access - of which we have plenty for all! - or whether they’ll try to nest.
Nature, you know? Always something new!
The mockers in Henderson were horribly territorial and it was common to see people with umbrellas when they went outside, because the mocker would dive-bomb them. Nasty little critters! And there wee so many of them!
And as my mother would say, “Nature! Ain’t it GRAND?”
They were probably extra-aggressive due to overpopulation relative to the habitat. My mom says they get that way in Florida in the spring, too.
I’m going to clean the stove now, so I’ll have an Accomplishment for the day.
I’m pretty sure that’s what it was. But the next year, there were hardly any birds at all, not even the egg-stealing crow that harassed the mockers. The only bird we saw or heard the next year was the red-tailed hawk. Even the pigeons were gone, for which I was very glad.
I’m too tired to have an Accomplishment for the day. Or even an accomplishment. I think the shower was the best it’s going to get. Not to mention its gloomy again.
I learned the psalm for Mass, but I’ll probably have forgotten it by the time I need it!
I finally found the link for Sacrament meeting and I guess it’s a good thing I decided to stay home. The company just called to say both of their “trucks” broke down in the mountains and they had to come down for repairs, so no elk hunting today. But could we get together?
If I had gone to church, my phone would have been shut off. So she’ll be here after 0930. What a change in my Sunday routine. ;o]
Things work out in a variety of ways. No elk hunting? Darn!
Bill the Cardinal is twooop-whoooping his, “Look at me, girls!” song at the top of the tree. Sounds like an early spring.
I read not to long ago that cardinals mate for life. Interesting!
I don’t know if you’ve had elk or deer meat, but I prefer elk. It doesn’t seem to have the gamey taste that deer meat has. But cooking deer venison in a little curry powder will get rid of that.
I don’t think any of the Missouri relatives ever gave us elk.
Elk is a little like well-aged beef. Pretty darn tasty. I like it. But its been a long, long time since I’ve had any elk.
I don’t know if I’ve had well-aged beef, either. We’re pretty cheap around here!
Mass was a success. So nice to see all my epople again, even though it was only two weeks. I’m thinking about a nap.
Sweet little morning floof! Thanks!
Good morning.
I need to go hang up the clothes. Then I might consider a nap, though that may or may not happen.
Yesterday was a strange day.
Kitten moved to a happy home with her brother, according to the poster.
In the phone conversation yesterday, I found out that Lingo-lover is allergic to cats, and my Favorite Son has suddenly developed an allergy to them. He had kittens and kids since he was two, the latest was when he was in his 20’s. They DID suggest I “get a little dog, Ma.”
Hmmm...I hate nervous little yappers...
Ugh, don’t get a little dog. Once you’re all settled in, maybe some kind of suitable pet will come your way. If not, maybe there will be a bird rescue nearby. I think it would be brilliant if you could be involved in socializing and re-homing needy birds.
I don’t know if I want to re-home needy birds again. I get too attached to them.
