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.

Well, my pick-up time is between 0700 and 0800, and I’m sure the roads will be dry by then. One thing Utah has is good snow removal equipment! Driving in the snow is like riding a bicycle: once you learn how, you never forget.
The clothes have been hung up in the closet and the socks and dainties are waiting to be folded, but I’ll get that done after I get back from Walmart. I think next week, I’ll try for a delivery, just to see how it works out.
More gloom and wet today, with a continuation of a winter storm warning. I told my Favorite Son and his wife that all this wet stuff was coming their way. The groaned.
Well, that was a busy Monday.
Happy Tuesday, everyone.
We have some winter storm something-or-other from noon today through 10am tomorrow. In NYC that would have meant panic grocery shopping all last night. Here they seem to yawn.
This winter storm warning has been in effect for three days now.
I can’t wait to see what’s next! ;o]
It’s probably time for Chicken Little...
Good Tuesday morning to you.
We had a Monday?
Raining, raining here. The cats are in the dumps. I gave Shannon her pill, and she called me something unspeakable.
Shannon has always been mouthy, so...
Winter weather often makes cats in the dumps. They have no way to charge their batteries without sunbeans.
The snow won’t be melting any time soon. The temp is still at 26° heading for a high of 38°.
Brrr.
Yes, and I’ll be going out in a minute to try and clean off the windows. What fun, eh? At this moment, I’m very happy that Rocky gave me a beanie and some warm gloves.
Good luck. Rain, rain, rain.
HAH!
I was just getting my gear on to go out and I got an alert on the phone from Walmart saying my order was ready for pick-up.
It took almost 30 minutes to get the snow and ice off the windows and the doors. And then I couldn’t find my flashlight so I couldn’t figure out how to get the defroster on...the dash lights don’t work since the heater core was replaced, but he didn’t seem in a hurry to correct the problem.
Anyway, I didn’t even have time to turn on the GPS so Walmart could tell when I was there, and I had to call them. Boy this was a cold morning for an experiment! However, I found my way home on the shortcut a little easier because it was light out, and I knew the road I wanted was opposite the golf course.
The good thing is that a light has been installed at that intersection since the last time I went to Walmart — last week. And it was green in my direction!
The little gal was personable enough and even showed me how to schedule a delivery. Painless. It may happen sooner than I think, though...
Congratulations on your successful excursion. I walked out to the mailbox to mail the house payment. That may be my only outing for the day!
Thanks! It seems rather strange to look out and still see snow on the ground. It’s a whopping 33° so I don’t think too much snow will be melting too soon.
In the meantime I made some chocolate chip cookies. I didn’t use the Kitchen-Aid Wannabe, but I should have, because it would have been SO much easier. Lesson learned!
I wish I had saved the cookies for another day and made brownies, instead, because my back is killing me now. It did NOT like me being on my feet. Since another bunch of storms is coming, the barometer is dropping and the Admiral Fitz had large crystals like moth antennae. Pretty in a creepy kinda way. But this place smells delicious!
I have never given a cat a pill. I have read this: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC372253/
Pretty cute!! All the cats I’ve had may be submissive for the administration of the pill, but they’re also quite adept at spitting them back out, intact.
No winter anything here yet. Of course, I hope those National Weather Service things have padding in their schedules.
Shannon is taking hers with pieces of sandwich meat. She knows there’s a trick, but she wants the meat.
Time for nap, after two Jungle Book stories: the one about the mongoose and the one about the crocodile.
Well, it’s snowing NOW.
One of my favorites was Rikki-tikki-tavi
You know, the day is going to come when people will look back wistfully to when you could read books to your kids like Rikki-tikki-tavi instead of Heather’s Dad Used To Be Her Mom.
