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.

Which is probably a good thing considering their ages!
Pat and James are adult men by Elizabethan standards. On the other hand, metaphors and puns require a lot of context. They do enjoy all the insults!
I love puns!
My family, at one time, had some very punny people in it. Sadly there are only four of us left, only one of whom has a spouse. She was good in her day, but like my mother’s humor, it was mostly what I called “unconscious.” Always funny and often hilariously so.
We have read from the soil manual until we’re all ready for Naptime.
The bed is made, the lunch has been had and I’m ready to tip over.
The wind is incessant and I’m cold. The weather is colder and uglier than it was earlier and that means my body is rebelling and I’ll say no more.
Except that my Naptime will be later than yours, and last quite a bit longer. At least eight hours longer, if I have my way!
I hope you have a very good naptime! Being up extremely early *and* cold is exhausting!
The sun has come out here. I’m going to turn on a podcast and clean the cabinets where baking pans and mixing bowls are kept. They’ve gotten all mixed up since the last time I did it.
She’s good. Still a puppy. I’ll be glad when she grows up. Right now I need to remember to balance the leash between the two arms or one will be longer than the other.
Makes me glad my pets are cats in late middle age.
I’ve seen you-tube videos of people walking cats on a leash.
It makes me wonder how much blood they lost trying to teach that to the cats.
They say some breeds take to it okay if you start early.
The Long Naptime is a dream. Rocky has been very noisy of late, in her own nocturnal habits, and twice during this night, she has dropped something in the bathroom or slammed something in the bedroom and it has awakened me. This last time, I’ve had just enough sleep to where my mind went to work.
So here I am. I’ll be sorting my pills soon, but for now, I’m going to turn the space heater on because its quite chilly in here.
The wind knocked out the TV yesterday, so its a good thing that I watch DVDs. It has died down now, but I dread it at Walmart, where it’s always terrible. And cold. The TV is back up, but it’s mostly white noise for me — just something to keep the place from echoing.
At my house, there is almost always a person in the bathroom, which would make it a struggle for the cat.
Some of my family members are slammers, too.
Good morning.
What a pretty DLH marmalade!
Good morning.
Rocky has been getting worse over the last few weeks, claiming insomnia, but that doesn’t give her a license to keep me awake. She’s been complaining about it, but the more she complains the worse she seems to get. I want to talk to her but I don’t want to wake her up, so I’m thinking of talking to Chuck. He get paid for ticking people off, and I don’t.
I was sleeping so soundly, too!
I’m usually up long before the rest of my family. I plan ahead so I don’t need to disturb the others, and I don’t bang, slam, or run the vacuum.
It’s not that hard to be a considerate neighbor.
Because of my very early training as a military wife in housing, I’ve always been respectful of my neighbors, and it has carried over into private life. When others are sleeping, whether it’s because of my early hours, or someone’s nap, I be quiet!
Which is why I’ve usually given up my bedroom to visitors — so that I don’t disturb them. How hard is that? Evidently, very hard. Even when I was moving in, I tried to wait for 0700 before I began to unpack when I was in a room with a common wall.
Common courtesy.
Good morning. We survived Monday.
Happy Tuesday!
Happy Tuesday backatcha, ArGee!
