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.

I haven’t mastered color, either.
I’ve been writing letters and wearing Vlad’s shoes to carry them out to the mailbox. Big feet!
I was telling someone earlier today about the days when you had to type WIN to run Windows.
I miss those days...
Some times.
Especially when you are trying to manually push the limits, or tweak a process, on some system/chunk of hardware.
I can do color if I have a cheat sheet handy. I have one, but where? is the question. Nowhere close, for sure.
A month from Friday is my two-year anniversary here. Go figger. My recertification appointment is the 24th, so I have to get all my bank statements from six months. ARRGH!
Chuck said the mail hasn’t come so I asked him to let me know when it comes, in case I don’t see the truck come in, so I can grab the offending envelope and do something with it.
It’s not completely overcast, but I keep hearing thunder and the wind is up so that I can hear the wind chimes. I moved them from the back to the front, so I can hear them without being awakened. :o])
We had to learn Windows 5.0 and 5.1, the latter of which used a mouse. We didn’t use one, so...yeah. Typing WIN just to get into it. And the 5” floppies.
Those were the days. It was a fun time. Until the riots. They rioted me right out of a job, and I had to go back to Vegas to find work.
We got mail. It was almost all political ads, except for some Magic: The Gathering cards Vlad had bought on the exchange site.
I remember the first time I saw IBM MCA and you couldn’t just flip a DIP switch or shift a jumper from one pair of prongs to another to configure your card. My thought was, “Who would ever want this?”
It’s gone so far beyond that now.
Then there was Windows ME. The first virus sold as an operating system.
Just so Face doesn’t get ‘em all.
Nevermind, I’m not doing 10 more. Face will get the next one, too.
Hi. We had meatloaf for supper. DP printed out a recipe, and I put in the ingredients that sounded okay, as well as a few others like cornbread stuffing mix. The boys liked it.
Patrick will drive Kathleen and me to Cub Scouts in about half an hour.
How are you? One reads of more restrictions on life in England.
Don’t forget to Vote. Or I will talk to you for four hours on the subject of my choice. :D
DP and Patrick early-voted at the Fire Department a couple of days ago. I plan to go to the regular poll - the elementary school - tomorrow around 10:30, after my WW meeting. I should miss the early people and the lunchtime people!
Thanks to our new sidewalks and traffic circle, built very slowly over the summer, I can walk to the elementary school without even more risk of death than driving with Patrick. But if it’s raining, I won’t.
That’s it TC, just like that. :D
We go back into lock down on Thursday. Thank goodness I’ll still be able to go into work. The lunatic has decided that it will be for a whole month this time. “But we will be free of it by spring” . Thanks BoJo.
If you’re going to be locked down, I guess this time of year has some advantage over the summer. I wouldn’t mind if my life shut down again.
The Murder rate is up.
The last was only ten miles from here!
IT was classic Midsomer...Rollled up carpet ,quiet woods, the lot.
