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.

And it hasn’t been that hot, at least for me. My phone said it was 88 yesterday afternoon, but the archery range is shady that time of day, and there was a pleasant breeze. My friend who was working at “Field Games” said it was very hot and she was exhausted.
Congratulations on the new phone!
We’re a “throw-away” society, now. “They” don’t build things to last because there’s no money in it.
Still, there’s a lot to be said for beautiful wooden furniture that was built 100 years ago! My bedroom set was built in 1978 and it’s beautiful! And heavy. And staying here. ;o]
Wow. That’s almost like a day job.
Yes, Pat can help and then he can reminisce about how much fun he had when he was part of it all... ;o]
I guess with our heat wave here, I’m more away of the heat (or lack of it) in other areas.
Now, I need to go shower. If I don’t finish before you leave, have a good day! Pictures help! ;o]
And two cards came in yesterdays mail!
It has been decades since I had a “real” day job.
Oh, good. It’s the least the USPS can do.
Welcome ...
... to the undead thread.
Feel free to look around. Be careful of Darksheare’s coffee.
Good morning. Happy Humph Day!
The phone is almost mine. I had hoped the old one would have died due to low battery overnight but the alarm went off this morning. I couldn’t shut it off, of course, so I buried it in a stack of clothes until it decided to shut up.
Time to become a novelist.
I’d read it.
As long as you don’t have some silly ending like all the flying saucers piloted by felines descending to take their rightful places as rulers of Earth.
“It has been decades since I had a “real” day job.”
Ditto, me!
I hate when that happens. Worse is when they die before you can transfer all the data.
And happy Un-Friday Hmph Day!
It’s getting light in the easternmost reaches of the valley. I’m going to miss all these mesas. I need to just stop the car and take pictures!
Nah, that’s been done.
So, seriously? California is offering $100 million to bail out its marajuana industry?
Are you telling me that the State of California can’t even make money selling drugs????????
Check your email! Please?
OK. I’ve replied over at the new castle. Want me to “borrow” T-C’s kitteh ping list and post something here?
