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.

Good morning, if I missed it. I mean that in the “any morning you wake up above ground” sense.
With no whack or snark to be had, we might as well all just crawl back into bed.
;o])
Tempting, but check your FReepmail.
I have a little whack in inventory.
I’m not out of whack.
Good morning.
w00t!
You made it too easy on her.
Actually, I used to use the “any morning you wake up looking down at the ground” line but then a Christian friend asked, “Why is it a better morning to wake up here than in Heaven?”
She stumped me, so I had to stop saying that.
Well, yes, but honestly, I’m pretty busy with stuff and I’d feel bad if it didn’t get done.
I have that thought, too. What would Mrs. ArGee do if I didn’t finish x. But I have to admit, if Jesus calls me home, He can take care of Mrs. ArGee.
I get that, but I’d rather not think of it right now. It would be hard on my mother, too.
But just in case, ‘Face knows where my secret cash stash is.
Everyone has access to my secret cash cache. Just look in the nearest empty pocket.
Heh. My wallet is my public cash stash.
*tagline*
Heh, amusing.
There is a big difference between looking at the blades of grass vs looking at the roots...
Yes, that is true.
We were threatened with Weather, but it didn’t happen.
Even so, we had some laughs and talked for 40 minutes again. I really do miss that ol' guy and his subtle sense of humor.
Speaking of old guys, I was just finishing my pills and getting my snack ready and I heard some thumping against the kitchen wall. I opened the back door, and there was the guy who lives in #1 helping himself to my hand truck. He said he was going to take a recliner to the dumpster. I thought he was mighty rude for not asking me first but I was too shocked to say anything. I will say something to Chuck today, though...
It was very rude not to ask. I hope he brought it back!
Yes, I checked this morning just before I went to take my shower and it was there, but the whole thing has left a bitter taste in my mouth. He made it a point to tell me he was divorced and didn’t know why, and when I told him I was headed for bed and he disturbed me, he tried to shame me by saying “it’s only noon.”
So I’ll see Chuck today. I met this guy when he first moved in and he tried to schmooze me then, but I told him I didn’t socialize. Chuck knows it and he will warn this guy off.
“Divorced and doesn’t know why” is a red flag!
