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.

Wow. This usually comes in a letter, but any way I get the details of your trip is good! The only way I seem to get vacations is to read about other people’s. It happens when one is a Single Adult.
Such an interesting morning kitteh!
I visited with Chuck for a few minutes, yesterday, as he was out all last week, and this week I just haven’t felt up to seeing him.
I slept in this morning. I wasn’t going to but then, I thought, what have I got to get up for? Maybe this week, I’ll reset all the alarms forward another hour, the wakeup alarm as well as the pill alarms.
I don’t know if I’ll get much packing done, but even one or two boxes is progress.
Good morning. I support sleeping in when one can! I need to be out the door in about half an hour for my range officer class.
Happy May Day!
Good luck with your range officer class!
Well, Godspeed on your journey (in case I get lost again). Haven’t spent much time in AR but it’s reputed to have a lot of interesting paleontological stuff.
Thank you. Good to see that y’all are home intact.
Thanks!
I’ve seen a lot of AR and we lived over three years in MO, so if I could get used to that, AR will be OK. The packing is beginning to get to me, but I do what I can in one day, and then have to rest a day.
There are a lot of very interesting places to see there, so I’m looking forward to it.
I’ll ping when we’re about ready to shut down and head out (maybe two months from now) and I’ll post from the road, so don’t worry about being lost! I’ll do my best to find you!
;o]
The Science Museum sounds great!
Hadn’t seen a ‘ping’ since - hope all is well...
Supposed to read “since Tuesday”..
I was on a campout with my family. Now I’m back!
Quite pleasant. Cool day, only three of us in the class, so we were finished around 2:00 instead of 5:00.
That was probably more pleasant than if it had been a larger class, especially after spending a few days relaxing.
I was in bed, trying to help some of the pain go away, reading more in “Tent Life...” and wondering if he ever loses his sense of humor. From the bookmark, I’d say I’m about two-thirds of the way through it.
The temperature got up to 88° so I had to relent and turn the A/C on. I’ve never been in a place that seems to keep out the cold (ha-ha) in the winter and keeps in the warm in the summer. The place in Henderson stayed cool in the summer and was warm in the winter. And it was very large.
George stays very chipper. I hope you got back to sleep!
I hadn’t been to sleep. I was trying to stay awake so I can rearrange my schedule, somewhat for my move and my “new social life.” Then I decided to shut off the alarm again. It was 0430 when I woke up and I think it was because I got cold. The mattress pad automatically shuts off after 10 hours, and I keep forgetting to re-set it around 1700.
I’ll have to do better than this if I expect to finish the packing in a timely manner. It’s messing with my tea cycle something fierce, too.
All of the kittehs are marked so beautifully!
Good morning, she says, after she prattled on about her sleep...
(I need to do better than this!)
How’s the yard work/plans going? You haven’t mentioned it for a while, and I’m curious.
Good morning. Beautiful kittens, aren’t they?
There has been no progress on the yardwork plans. I don’t know whether DP has set up anything with the contractor.
He and Tom are off to run their half-marathon. I need to take a shower, get dressed, and start working on music for Mass. We will be a capella today: Asuncion’s grandson has Covid, and the office said “to be safe” she should stay home this week, even though she’s been vaccinated.
Just had my shower and while I was combing my wet hair, I began to think about my plans for a new schedule. I need to write it down in relation to my pill schedule. And church. And laundry. And tea cycle. Unngh. My brems boggle.
Wow. A half-marathon. My biggest problem is that I have no one to exercise with. It seems like the rest of my life is hanging in the balance, waiting for this move to AR. Until then, it seems, nothing can happen.
One would think, if the Covid “masters” are correct, one should be safe in not being a carrier if one has been vaccinated.
The “experts” keep saying different things. If I had it to do over again, I would have made a Command Decision that Asuncion was fine, but I felt at the time she called me - Friday morning at the campsite - that I ought to ask the church office to decide.
