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 took a chair out to the front lawn and read a book while listening to Tom the Mocker.
I thought maybe it might have slipped down by the console (new mail van) when he grabbed the mail, but unless I see him on Monday I won’t know. I don’t know if Chuck will be here, but if he is, I’ll ask him to let me know if Adam or Not Adam shows up so I can run up and ask him to check.
Without the daily digest, I never would have known. Would I be better off? I doubt it. One thing is for sure: I was super industrially annoyed and immensely depressed. My birthday just isn’t complete without a card from you. Though the card I got earlier in the week would have done, had you not sent a specific card.
FS son said he was annoyed because he wanted a Sam (because of my dad) and then he married PW who had her own Sam, so James Samuel became James instead of the Sam he had been called all his life. I never knew why he had to give up his name, when Sam could have gone by his middle name, whatever that is. So it was an annoying day for both of us. Well, all three of us.
Were you annoyed that Tom went home instead of staying longer, or overnight? This is almost as bad as Mother’s Day!
No, it was fine that Tom went home. He’s an adult and needs his space, and he helped out this morning with a good attitude.
They could have both been Sam. Just call them Sam One and Sam Two.
They’d better find the card!
Tom needs LOTS of space!! I’m glad he’s good at helping, as well.
Yes, they both could have been Sam - Sam D and Sam R. We’d all have been happy, including the two Sams!
Yes, they had better find the card or I’ll go to the local post orifice and have a meltdown in the lobby. Not a pretty sight, seeing an ol’ lady, cryin’ and cryin’...
OK. I’m leaving now. See ya tomorrow. :o]) Thanks for the card, even if it hasn’t come, yet!
Kitteh makes my Sunday floofy.
Good morning.
I woke up around midnight, but this time, I took my nap earlier. I went back to bed around 0200 and got up about 30 minutes ago. I had to wait for the laptop to finish its contortions before I could do anything so here I am.
In a few minutes I’ll go shower, but I suspect I won’t be going to church. I’ll try to watch from home, but the few times I’ve tried in the past, the sound has been wonky or non-existent. If Dick Tracy could only see us now!
The weather map says it’s one degree cooler here than where you are, but the sun is still below the mesa. I’m going to miss the mountains.
The Perfect Wife called me on her way to the airport in SLC to wish me a happy birthday. She sang the birthday song and instead of my name she inserted the word, “Mommy.” I’m not sure how to react to that. Her own mother died when PW was 14, and I guess she had the step-mother I was accused of being. Anyway, I don’t know whether to ignore it or encourage it.
I suggest ignoring it.
Good morning. I’m about to go for a stroll outdoors, and I’ll have a shower after that.
Yeah, that’s what I thought, too.
Just had my shower, and I’m about to have Second Breakfast and will listen to an uplifting talk, then make the bed. I won’t make it to church today, but as I said, I’ll try to watch it on Zoom.
I ended my stroll because the sun came out, and I hadn’t put on sunscreen. Time for a shower!
I listened to an uplifting talk, and it was so good, I listened to another. I was into the third and realized that it was time for church. It always takes me forever to get the Zoom feature for the Ward. (A different link each of the Sundays of the month.) At least the sound was working this week!
Anyway, Happy Sunday. Did you get to stroll very far before you had to quit?
I need to finish a letter.
Done. I ran out of paper so I had to reload the lower tray (the thing won’t default to the upper tray) so I’m finally done with Sunday stuff. The bed is made and my prayer has been said, so now, it’s time for more pills.
Golly. My days go from pill alarm to pill alarm. ERK!
We had a nice walk and then Mass. Now I’m thinking of a nap. DP is planning to go to the hardware store.
The yutes are bickering.
Ah, yes. Sundays with kids. Nobody who ever had kids at home wrote pleasant songs about tranquil Sundays.
I just watched Nova DVD about the Zeppelins in WWI. Pretty interesting! Things I never knew! "Zeppelin terror Attack," in case you're interested in WWI stuff.
Oh, yes...have a good nap!
I’ll send you picture tomorrow of our new bird friend, Margaret Thrasher. She sits on a rosebush branch, yelling, “Chick!” at Jake. He is underwhelmed.
Good morning.
So she just showed up on your rosebush? No fanfare? No parade? No wonder Jake is underwhelmed.
I’m off to sort clothes in a minute. Then laundry, but it won’t take long today. No dryers involved. Then we’ll see if the extra morphine helps.
Look at the precious little floofs! Same litter, I’d guess!
Guten morgen.
Done with the laundry. Well, the washing part, anyway! The hanging part always takes me a while to get to because of the washing part.
I DID get a belated call from my Real Brother and a belated text from redhead and she said her fingers didn’t want to type the figure. I told her my eyes didn’t want to see it, either. I’m at that point once again when, if asked my age, I have to do the math. ;o]
Anyway, Monday has started and we’re off and running. Are the gas prices any better, now?
Gas prices were in the $2.70s. It’s the supply that went away. It’s coming back, now.
We’re still over $3, but that may be because of our situation between vacation areas — Vegas, Zion and the other Utah parks.
At least I don’t drive very far, these days. Not because I don’t want to — I would love to explore the entire county, including little out-of-the-way shops and yard sales. But the BB SUV isn’t up to snuff.
