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 always print in black and white.
Since I print patterns, it’s usually best to do them in color because of the multiple size changes. These days, they’re all in color. The older patterns often aren’t, but they also often have wide colored borders on the page that shows a description, and if I printed them in black, I would go through a lot more than I have done.
Until I can get the print heads cleaned, I’ll have to continue to print using just black.
That makes sense.
Astonishing moment wild black bear climbs inside a jacuzzi to warm up in the cold mountain air
Video of the event at the link. Apparently the city slickers aren't wildlife lovers.
I was that close, once, (through the glass) but we didn’t have a camera handy and no one dared move. It was in Alaska. ;o]
What a jerk.
And thank you for the cute story.
I have not seen bears in my neighborhood, yet.
Well, I was short enough to sit on the kitchen table, so I had a ringside seat, as it were. He was on our porch.
You’re welcome!
We have some family who live in an area shared with black bears.
If humans take some common sense precautions and use their noggins, everyone muddles along.
They are beautiful, fascinating critters.
We know someone who had to get rid of their beautiful brass lever door handles because a black bear was using them to open unlocked front and storm doors.
They’d forget to lock up when at home.
So they went to round knobs that even those wonderfully evolved bear paws couldn’t manage.
That said, I told them they were lucky.
We live in an area with serious crime issues.
I’d rather deal with an ursine home invader than a human one.
I saw a documentary once about the adaptability of bears, and it was absolutely amazing how they could reason out ways to get in or out of containers. I never knew they were so clever, but hearing that they sussed out a lever door handle is not surprising, considering what they were able to do in the film.
Back when we lived in NYC Mrs. ArGee and I would get cupcakes for our birthdays since we could eat them without having to throw large amounts away.
We haven’t found a good place to get cupcakes since we moved out.
Yes, kitteh, it is Friday Eve. I can hardly believe it either.
Happy Friday Eve, everyone.
Is there a Bundt cake bakery, such as “Nothing Bundt Cakes”? They sell individual-sized Bundt cakes.
Wow. Friday Eve, already?
It just seems like Thursday to me.
Indeed. ;o]
It’s another gloomy day, here. I got up not feeling too badly but as the time passed, I began to feel that physical depression that can mean only one thing — bad weather. The Admiral agrees with the barometer, and I want to dig a hole and pull it in after me.
I’m going to take the kids to church in a little while.
I forgot. What are they doing? Cheer me up by saying something fun, I hope! ;o]
(Or something.)
