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.

What an excellent idea!! But would we need to learn to speak English?
W00t!
Tippy Kitteh!
Good morning. My new inks came so I can now finish the print job and get another one in the works.
I’ve almost talked myself into shopping on Monday or any other day because Tuesday is so stressed, what with pill sorting and clothes folding. Since I went to Walmart yesterday I don’t feel that anxiety of trying to sort pills, shop and fold clothes. One less stress to deal with.
Nothing more last night, though I waited. I was so very tired!
The pills have been sorted, and I have some things to do before I fold clothes, but I’m not in a massive hurry to get it all done. I will run some errands later - library, Walgreen’s, Sinclair, bank. Unngh. But for now, I’ll concentrate on the stuff that needs to be done here.
I have a good ear and could pick up a darling little accent very quickly, if I were immersed among them.
Since you’re making all these plans, does that mean you’re feeling okay this morning, with all the usual caveats? As I told my dentist, “Mumble mumble under the circumstances, Dr. Dhulab. You?”
We have Stuff today. I’m not quite alert enough, yet, to organize it, but we will do Stuff. Maybe I’ll get Elen’s coffee maker mailed off to Okinawa. I bought a box for it. I was kind of hoping her “graphic novel” would arrive to be included, but Dover hasn’t shipped our order yet. They did say they were doing their best!
I suspect that, I, too, could pick up that darling little accent and make it my own in a short amount of time.
When I make Plans, they are always with the caveat, “Subject to change without notice,” because that’s the nature of the disease.
The clothes are folded and put away, and I’ll get on to the next project. I have to get a package ready to send to my Favorite Daughter and The Guy so they’ll get it for Christmas.
The other stuff will happen or not, between now and Christmas, but happen it will. Eventually. Some days, the best laid plans of mice and men are often screwed up by reality.
It’s fun to think about it, at least, although the snow is a little off-putting, given how cold my feet are.
Yes, I think of the cold, the damp and the wet, but then I remember that life is a series of compromises, and in order to learn to speak with that darling accent, we have to be willing to immerse ourselves in the culture and climate!
That’s true. Also, they have warm clothes and waterproof boots in England, or so one reads.
I’d like to get a hot shower, warm clothes, and boots on, but there’s a previous occupant of the bathroom. Oh, well.
Also, Jake spewed again.
Dover says our order has shipped, but with the Media Mail free shipping, it might be ten days before we get it. I’ll try to mail the coffee maker today or tomorrow, and the book can go separately.
T'was not always the case...they suffered most awful from chilblains well in to the twentieth century or so I read.
Before the webz I never knew what they/that were...not at all pleasant, always needing a shilling for the two bar fire...imagine having a coin operated heater in one's house....and a coin collector coming by on a regular basis.
Maybe the Benny Hill skits of the milkman and the lonel housewife were merely the tip of the iceberg, milkman, gas man, BBC telly licence inspectors tramping in and out for a cuppa and more...wink, wink, smirk.
Poor Jake. I hope nothing is wrong with him.
I listened to another uplifting talk, so Things were delayed but I’ll see what I can get done in the next hour. I was thinking of having the USPS pick up the packages I have to send out so I don’t have to darken to portals of their facility. I don’t stand in line very well, what with my back the way it is.
I haven’t gotten anything from Dover in a long time, but that doesn’t mean I don’t slobber on the online catalog pages!
Dismally Inept Lawn Service showed up yesterday with a surprise. New BIG truck and massive leaf blower! As soon as he got all the leaves into a hugh pile in Rocky’s parking spot (she parks in front) he left and the wind began to blow as soon as he made it to the street. Sorry, but I thought it was ironic.
w00t!
Happy Tuesday, everyone.
Puppy had another seizure this morning. So the intervals are 13 days, 11 days, and 13 days. Her hour of the morning keeps moving up by 2. If she keeps to that schedule her next one will be 2:30 am. But we were much better at containing the mess, even though she has had the runs for the last few days.
Well, there is always that to contemplate. That “wink,wink, smirk” aspect!
I always wondered why there were tapestries on the walls and the windows were so small, furs on the floors and why folks were always dressed in bulky clothes. It’s because they were COLD!
But now, they have waterproof boots and warm clothes.
Sorry about the puppy.
Happy Tuesday!
That’s so sad about Puppy. I bet they scare her, if she knows they’re coming, which she probably does.
Sorry about the messes you have to contend with, but I’m sure if Puppy had her choice, she’d be able to alert you so you could get her outside.
This one wasn’t as “bad” as the last one. Bad is subjective, of course. Maybe things are getting better.
Yes, maybe it’s getting better.
I’m not sure she’d want to be lying on the ground in 20 degrees. We’ll manage.
I’m not sure what kind of warning she gets. We get that she’s about to throw up. The seizure follows shortly after. Fortunately, this morning, it was far enough in advance for us to get out of bed and get her to a relatively unmessable spot.
Well, I wasn’t exactly thinking of her staying out in the cold. That’s something I would never do to any animal.
I meant to be able to get her outside to contain the mess better. But if you were able to get her to an unmessable spot, that’s wonderful!
