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.

A pun isn’t really a great pun until it is all groan up...
I think you must be right on that... At least it’s not two-thirds of a pun... ;o]
Very funny, nully.
I didn’t yodel or change my phone message, either. I’m going to Walmart with whoever gets in the van.
Today is National Change Your Password Day!
I’ll be going to the post office soon, so mail a package to a FRiend!
The day is gloomy again and windy.
They can’t make me change my password!
I’ve been to Walmart. Then I called a driving school about classes for James and Vlad, and they said, send an email and we’ll get you all the information. I love it when something is quick.
I also made an appointment for a physical - new doctor, my old one retired - and filled out the forms for my colonoscopy. I’m mailing for the forms back, and one day, they will call to schedule an appointment.
See, you noticed! That shows you’re alert!
The Package Bunneh should be arriving at your place on Thursday!
Yay!
WARNING
This machine is subject to breakdowns during periods of critical need
A special circuit in the machine called a critical detector, senses the operator’s emotional state in terms of how desperate he or she is to use the machine.
The critical detector then creates a malfunction proportional to the desperation of the operator.
Threatening the machine with violence only aggravates the situation. Likewise, attempts to use another machine may cause it also to malfunction - they belong to the same union!
Keep cool and say nice things to the machine. Nothing else seems to work. Never let anything mechanical know you are in a hurry.
Now I need to warm up. Oh, yes...I think I put some bookmarks in that package, but I can’t remember. I’ve slept since I sealed it. :o|
That’s terrific! America needs more lerts!
Very excited about the Package Bunneh! I’ll make sure the cats are secured, to avoid carnage.
Well, there’s something in there for them, as well, so tell them to stifle themselves. ;o]
I can tell them, but they won’t listen.
Not a problem. I’ll reverse it from 12345 to 54321.
Kinky! I like your style! ;o]
Yes. I forgot. They ARE cats and that means they come with sharp pointy things built in.
Yep. The boys think Shannon has gained weight since she started on the thyroid meds a week ago, but I think it’s just that her coat is in better condition. We’ll see when she goes back to the vet in about a month.
Geologists ‘resurrect’ missing tectonic plate
