Geologists 'resurrect' missing tectonic plate
Phys.org ^ | 10/20/2020 | Sara Tubbs, University of Houston

Posted on 10/20/2020 9:33:20 PM PDT by BenLurkin

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.

Dental appointment entirely too early today.

Got me to thinking, always a dangerous pursuit with inadequate coffee:

I should probably have a breath mint. I'm down to my very last tic tac.

I wonder when an oral version of Febreeze will come out.

Better yet, a pill!

That way the next day you can truthfully say, "My Sh!t doesn't stink!"

Must have more coffee...

My mother used to use chlorophyll tablets for our female cats, and tried to convince us of the benefits. But, my older sister, in her infinite wisdom, mentioned that it didn’t seem to help the cows or horses...

I took Frank and Kathleen on a mandatory outdoor walk. Later, James and Vlad’s Envirothon is meeting at the park, so we’ll have more outdoorsiness.

Off to the post orifice and the library where I’ll fax the form. I forgot some stuff at Walmart so I’ll stop at Lin’s again. Unngh.

You win!

I’d like to take a nap with a cat, but we have to go to the park for Envirothon.

All afternoon at the park. The teens did some work, though.

I sent a text to my Favorite Son and later, one to his Perfect Wife and she kept me busy. The guest bedroom/office will now have a door to the back yard where there will be a patio, gazebo and a firepit so “we can sit around in the fall and just have some girl talk.”

*face palm*

I’ve created a monstah!

I got a letter from Humana today, saying they will not authorize oxymorphone. Everything else that was listed that has too many side-effects is accepted, but not this. I may have to call and see what can be done. This drug is really ineffective in the current dosage, but the others would be bad for my CFIDS body. Unngh.

Now, I’m going to go back to bed and try again.

Now THAT’s a perfect kitteh bed!

Good morning.

Yes, I did get more sleeps, thanks. I read a little more in “Back to the Sources,” about making sense out of the Old Testament, or Torah, and that helped to make my eyelids slam shut. I’m not even 40 pages into it and already, the Old Testament is beginning to make more sense. I can put it in your stack of books when I’m done, if you think you might want it.

I’ve been reading “Tent Life in Siberia,” too, and the author had quite the sense of humor. I have to get a bilingual map of Russia, though, before I can get too much farther in it. I need to see where his journey takes him or it will be just a “story.”

I got out the atlas for “Tent Life in Siberia.” It wouldn’t have been such a commercial success if the author weren’t so sarcastically chirpy and likeable.

Good morning. Happy Friday Eve!

I suspect today will be a busy day. I would like to go back to bed like kitteh.

I don’t have an atlas. I did. Once. I’m sure an atlas would have cost much more than the map.

The author won my heart when he spelled out Russian words phonetically. Although I think the natives wouldn’t have been too impressed with his efforts!

Oh. Look.

It’s Friday Eve, and ArGee is the first person to notice it, as usual! Thanks! When one is retired (even forcibly) days tend to blend into one another unless one gets reminders.

How’s the puppy?

She’s good. Thanks for asking. The seizures are just a fact of life for her. And I don’t expect another for a week or so at the earliest. Of course, she could surprise me.

Oddly, the phonetics were pretty much like the Anglicisation ;-).

We have to get a new atlas every few years because the world changes on us. Vlad went through a phase where every time he saw a globe or a world map, he would check it for South Sudan and North Macedonia. Neeeeeerrrrrd.
