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.

Oh, no,no,no. I couldn't 'face being a monkey's uncle.
Happy Thanksgiving, everyone.
Berry crebber, Bob.
Good to hear from you!
Even if you do still have a tendency to crack bad puns! I’ve missed you. :o]
Don’t stay away so long, OK?
HAPPY THIANKSGIVING, EVERYONE!!
May your day be abundantly blessed with all things important to you.
May we always be thankful for living in America, and may we work hard to keep her free.
‘Face
:o])
Drop some turkey!
By all means, yes! Drop it!
Good morning.
The wind is blowing in fits and spurts and so far, I’ve gotten four hours’ sleep. Unngh.
I wrote up a couple of recipes, but haven’t figured out how to put them in the right folder. I’ll get it worked out, though. It ain’t rocket surgery.
I’ll put the pie in the oven soon and then maybe try to make something tasty. ;o]
Good morning. Jake came to get me out of bed around 5:30. So helpful.
DP and I are up, the cats went out, a few birds are suggesting it might be daytime soon. I just put a load of laundry on, so a child or two might turn up.
I haven’t decided where to start on food prep today. Maybe peeling and cutting up apples for Tom’s pie.
The pie smells delicious. Not sure what’s next though. I really just want to be warm. Every available surface in the kitchen has at least one empty packing box on it and that includes the chairs, so I can’t go in there and soak up the warm.
I put up a few Christmas decorations — snow flakes that are 4” across. That’s it for the decorations! Oh. And three nativities that stay out all year.
Well, move an empty box and sit in the kitchen! That reminds me of the Great Snow of 1978, when we lived in Newport, RI. My dad was stuck at “work,” Naval War College; the officers were sleeping on tables and floors with blankets that had been borrowed from the base hospital.
Mom, Russ, and I spent several days playing Monopoly at the kitchen table with the oven on for heat!
I decided to start with sweet potatoes. I’ll measure out the amount for Tom’s bacon-bourbon dish, then fill my pie crusts. That will let me know if I need to boil more potatoes!
The boxes are stacked as high as I need them to be so I have room to move around. I need access to the window and the door, so everything is stacked in the corner, but it takes up almost 2/3 of the room. In order to make it all fit, I had to stack the chairs, and there are boxes on top of them. The table is in front of them, and half of it has boxes.
I’m getting depressed just looking at them and not being able to clean house. I want to pack, but I promised me I was not going to do anything today in the way of work. I was just going to be thankful and consider all my blessings. Writing them down helps! ;o]
The pie is done and it’s beautiful! It says to cool it at least two hours, but it will still be warm then, I’m sure. I plan to eat around 1000, as that’s usually when I have my “big” meal of the day.
Dismally Inept sucked up some leaves for four hours yesterday, and now the wind is up to blow the rest of them off the trees. What fun!
Maybe your next place will have Tolerably Competent Lawn Service.
I’ve had to cook more sweet potatoes. When I’m done with that, I’ll start peeling apples.
I couldn’t figure out why I felt so icky and then I realized I had forgotten to take my next pain pill. Because I’ve been up since 2030 last night and took the last one at 0030.
When I get really tired, I get cold and then the pain sets in and I guess some days, I’m just not aware enough to realize what has to be done. :o|
This lawn service would be Tolerably Competent, even with just one guy, if he didn’t quit in the middle of a job. Maybe he was leaving town, but still — why start with cleaning up the leaves if you’re not going to do the entire property? I guess it’s my OCD at work again. Some days its worse that others.
Happy Thanksgiving everyone!
I hope your day is a very good one!
:o])
Same to you and your family!
Tom and I just peeled and sliced a dozen apples for his pie.
It’s already looking up.
Slept in. Had a marvelous cup of coffee. Going to shower up and head over to my Sister’s house where our Clan is gathering for a feast.
I have Happy Thoughts for all of my FR Friends... :-)
We made salted caramel brownies last night as our contribution to the feast. I’m also bringing a bottle of moscato.
We’re doing a “lefse day” on Saturday. Peeled up and mashed about 5lbs of potatoes last night. Currently chilling and ready to be floured, rolled, and tossed on the griddle. Yum...
Mmmmm, sounds great!
We have friends coming over to play Scrabble on Saturday.
Borrowing generously from Tom, I drained the yams and added a teaspoon of rum flavoring to the liquid, then about 1/3 cup of brown sugar, and cooked a slice of bacon until it was cripsy, then cut it into pieces and tossed the yams back in with the bacon to simmer while the dinner cooked.
I think it will be very good!
But of all things, my Gizmo can opener died and I struggled with the hand operated one. Not good on the joints. A new Gizmo is on my list for Christmas presents to myself.
Your preparations for contribution to the Thanksgiving feast sound absolutely delicious!
I love going outside on Thanksgiving day, just to smell the air.
