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 imagessimilar 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.

Speaking of riots, it’s looking more and more like the self-inflicted wound Biden suffered last Thursday may get Trump re-elected.
Which means the summer riots are going to look like a schoolyard tiff.
Well, maybe, if I still lived in Vegas Valley, and if I ever gambled, yeah, surprise refund!! ;o] But, no, neither.
Yes, Corelle reminded me very much of crystal, what with it’s explosive qualities and all. That episode convinced me to get rid of the remaining pieces (including the shards) and invest in something a little more durable. Like diner-ware.
Thank you.
Hey, y’all—hope you have a great weekend.
You’re welcome, and I hope you have a great weekend, too. We have Soil Lab tomorrow and Tom’s Birthday on Saturday, along with some Spanish choir and a cooking event of the Boy Scouts.
Humourless Experience.
Something strange happens to some humans when operating under external instruction. Any underlying personality just turns off . This makes things worse for the owner of a highly tuned B.S. Detector. Now you have two things to laugh at. Watching the Drone vanish up its own Cloaca is just painful. Time to walk away laughing ...Keep your darn Burger. :D
Soil Lab. (Dog Joke resisted)
I have 30 meters of Grey clay sat on a chalk substrate .
The top soil is a rich black, four inch thick, organic layer that only an ex Cow field can contain.
Surrounding fields are full of shattered Flint.
True Story:
A woman ordered fast food and wrapped up asking for just a cup of water to drink. The gal working the register hunted all over her keyboard for “cup of water” or some such, and — finding none — informed the woman that, unfortunately, she couldn’t do that. The woman said, “Oh, yes, you can,” pointed to a stack of clear plastic cups, and said, “You can give me one of those, and I can use the tap over by the soda fountain.” It took a moment to sink in, but it was as if the clouds parted, and The Voice spoke from the vault of the Heavens approving this deviation. Giving the woman that plastic cup without ringing something up on the register seemed a most scandalous adventure, but — Oooooo! — she threw caution to the wind and DID it.
Huzzah!
In the same vein, here’s something on-point:

Wow—sounds like a bang-up weekend!
Two kittehs for the price of one!
Good morning.
The neighbor to my left, Tom, the one with the mini-Schnauzer, has been ailing with dementia, and his dog has been cared for by his neighbor in the same building. The problem is, the neighbor, Brian, lets Jasper out several times at night and lets him bark, so my would-be sleep is interrupted several times a night. I don’t think Brian realizes the dog never shuts up the entire time he’s outside.
Nothing in the works for today, and that’s good because I need to take a few days to rest mind and body. Then Monday, I’ll go in to have my eyes checked for the laser surgery. This time, I’ll do my own driving. ;o]
Good morning. The cats suggest sitting smugly as an activity for the day.
James, Vlad, and I have to help teach soil science today, so we’ll spend the morning getting ready and the afternoon doing it.
Cats are very good at sitting smugly, so of course they would suggest it. Why wouldn’t they? It’s effective!
The shower has been had and Charlie’s letter, along with one card is ready to go out in today’s mail, but there is at least one more card that needs to be written.
Soil science sounds scintillating. Seriesly so.
“Know Soil, Know Life,” as the book says. Soil is so supremely important. “Marvelous are the works of the LORD, exquisite in all their delights.” Getting children from 10 to 18 to find soil exquisitely delightful is the goal.
Good morning. Happy Friday!
I always liked the study of soils, but then, all the sciences interested me when I was growing up. I would have been hard pressed to choose a science and stick with it, so I probably would have done better as a science teacher.
Everything the Lord has made is a delight to behold! The more we learn, the more I realize how very intelligent God is!
Happy Friday to you, ArGee!! I hope your weekend is safe and happy for all involved. :o])
Happy Fridays to all!
Well, sorta.
