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.

Unless they had lots and lots of windows!
True, that would make some difference.
I can see I need to get more windshield de-icer if I’m going to spend the rest of this winter driving in the early morning.
Never mind...I found another bottle in the truck. Leftover from last year.
Today is Change Your Voicemail Greeting Day and also Yodel For Your Neighbor Day.
You choose and surprise us all!
Wow, tough decision!
Choir accomplished, it will soon be lunchtime, and then I’ll take Vlad to get macaroni salad. We didn’t want to get it too early and have everyone down with salmonella!
Happy Birthday, Vlad!!
I’ll be going to the library soon, but in the meantime, I decided I needed a little levity in my day so I put in “Sherlock Holmes” with Robert Downey, Jr and Jude Law. Seventeen minutes into it, and it’s proving to be quite funny. I’ve seen it once before, but was concentrating on the special effects.
I like Robert Downey, Jr! But, of course, my all-time favorite was Basil Rathbone. In this version, Holmes and Watson are an enormously entertaining pair, whereas, the original paired Holmes with himself and the occasional Watson for a straight man.
Macaroni salad sounds very good! I think I’ll order some from Walmart so I can have it on Tuesday. Or Monday, depending...
Robert Downey, Jr., is always cute!
I wholeheartedly agree!! :o])
Now I’m off. I have to stop at Dollar Tree, and spend the obligatory $10. ;o]
Yodel For Your Neighbor Day
What could possibly go wrong?
8^)
Indeed!
In my ‘hood, they’d probably applaud.
Just about the time I got back from the library, one of the gals from church called and said they were going in to the thrift store in St George and could they stop and pick up the things that I had requested someone else do.
Of course, I said yes, so I now have more space to walk!
Excellent! I was having a nap with Jake, which was disturbed by someone who needed something from the room, and came down to find Tom the Son beating Kathleen at cards. I’m going out to make an animal friend, and then Tom can beat me at something.
I think if I sold everything else off, I might be able to swing that at about 40% LTV, but $24,000 in property taxes is a daunting proposal; definitely need to lease the Gardener’s house to cover.
It’s good to know that I wasn’t the only person who was concerned with the property taxes... I’d have to rent the house out and live in the Gardener’s house.
Nothing as much fun as a game with Tom, here.
And there won’t be fun today, either, since my dreams were so hideous. Now, though, I’m going to go take a shower and then write a letter or two.
Sweet! That’s just what I needed!
Good morning.
I ended up taking a shower and then I went in and took a nap for an hour. I should have made it two, I think.
But here I am, anyway. Getting up at 2330 is for the birds who hunt at night.
I’m glad you got some more sleep. It’s rainy here. Both of my short-person chairs have catballs in them.
