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.

There was a graphic novel of “Call of Cthulhu” at Ollie’s Bargain Outlet yesterday. I considered getting it for Pat, but didn’t feel like going through the line. Maybe another time.
I don’t usually read action fiction, although I have a soft spot for Clive Cussler.
That helps me to sort books to take pics of for you. I’ve been getting rid of my fiction for quite some time now. I was buying action fiction (or getting it free) because it’s difficult to concentrate on other genres with CFIDS. Now, though, most of what I read is non-fiction.
Clive Cussler was an author I really enjoyed, but I think I sent all the books I had to Charlie.
I just found “Call of Cthulhu” at Goodwill in NC online, so it will be coming this month. I don’t know why I waited so long.
:o|
Look! Kitteh says “Dis MAI snaky fing!”
Good morning.
Now I absolutely, positively MUST go take my shower.
Be back in a bit!
“Dis MAI snaky fing!”
“Useta be yer blanket? Owellz.”
LOL!
I assume the shower was a success. Maybe I’ll try it!
Yes, and I’m sorry about the delay. I found a puzzle and an uplifting talk to listen to so that time has not been wasted.
Which reminds me: Did the link for that puzzle work?
Yes, the link worked, but I didn’t have time for a puzzle yesterday. My shower was getting pretty tepid by the time I was done. Boys! I guess it’s good that they’re clean, even if I can’t smell it.
That was amusing.
Good morning. Happy Wednesday.
We got our snow yesterday. It’s not so bad. When it’s just more on top of what was already there it doesn’t really have an impact on life.
I would probably feel differently if I were commuting to work.
With as many pages of flamingos there were, it’s surprising they don’t show up on the main page very often. So I did a search, just to see and was overwhelmed by the amount and variety! LOL! Who knew?
As I went out yesterday morning to head for Walmart, there was a nasty little brown dog in my front yard, and it had the unmitigated gall to charge directly for me. I had bag of trash in my right hand and shook it in front of me, and though the dog backed up, it never shut up, nor did it stop trying to charge me until I got into the truck.
One day last spring, the nasty little thing charged me from behind as I was coming back from checking the mail. There was no one outside either time. The thing is, this is home to at least one owl, and if that dog owner isn’t careful, that little dog will be a good appetizer for a bird of prey.
I’ll tell Chuck about it today.
Good morning. It is Wednesday, isn’t it? ;o]
I don’t mind the snow, if we’d just get snow, but we get rain first. Then a freeze, and then the snow, so we have to scrape the ice off the windshields or wait until later in the day in order to go anywhere.
I just made sure I had plenty of Prestone windshield de-icer. I’ll probably have to use it in AR, too, from the looks of their weather map!
“... that little dog will be a good appetizer for a bird of prey.”
Sounds like nature taking care of its own issues. Also, whack it with the bag next time!
I’d rather whack the owner with the bag, if its all the same. I’m thinking said owner has no clue that there are owls in the area, or s/he would never allow the dog out except on a leash.
The dog probably only weighs about three pounds, so more of a snack.
Heh. I was just enjoying the hooting of a great horned owl that visits our neighborhood about this time each year. (Same one??) I heard him a bit two nights ago, and he was hooting away all evening last night.
I had the window open a crack so I could hear him better. And petting our cat, telling her “aren’t you glad you are an indoor cat so you don’t become owl food!?”
Although odds are it would be coyote food before owl food.
The area I live in is a mountain valley, but sometimes, “city folk” come here with no clue that the wild life is wild and is alive and to stay that way, they need to eat. It’s common for small animals (cats and dogs, tame rabbits, etc.) to become a meal. It will happen more often, now that spring is on the way.
I’ve seen crows in the area steal eggs, but no nocturnal predators grabbing a domestic pet. This is something I’d like to see, right about the next time I encounter that foul-tempered little beast.
I sometimes find a cat huddled by the door, making itself very inconspicuous, hoping the hawk or owl won’t see it. They’d crash into the door, I guess, instead of snapping up the cat.
