Geologists 'resurrect' missing tectonic plate
Phys.org ^ | 10/20/2020 | Sara Tubbs, University of Houston

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.

Cool. Did non-LDS emigrants use handcarts as well?

Wow. Thanks! That was very interesting! Both are beautiful animals. It’s a shame that people aren’t better stewards.

Yes, but most were bound for OR and went with the “Mormons,” probably for the safety factor. So there were only a fraction of non-LDS who used the handcarts.

Handcarts were used because oxen and wagons were hard to come by in the settlements that acted as staging areas. And as I understand it, there were some “freight trains” in the trek west, involving 20-mule teams. I mean, someone had to freight the goods to American settlers in CA...

It’s really extraordinary what people will do for trade!

Oh joy. I’m completely locked out of my main email. Over 2 hrs with the tech support yahoos yesterday and it still doesn’t recognize my email addy to allow me to log in, nor any updated password.

They have no record of anyone else having this problem, but a web search shows hundreds have the same unresolved problem.

Started about a month ago, spiked about two weeks ago and seems to be spiking now. That looks like a spike every 14 days to me.

Well that just bites. I’d be for getting a new main email carrier. Unless it’s an email password that allows you to access your worksite.

You might get the impression that they are incompetent and lying to you.

I got an email ad from a place that supplies Vegas Golden Knights’ gear and it was one of those “spin the wheel so see if you win blah-blah-blah” fully expecting, “Sorry, better luck next time,” but was treated to a a free (overpriced) coffee mug. My choice? “Ladies of the Knights.” Why not? It was free! I mean it would sit on the shelf forever, at $19.95, but we’ll see if it actually shows up.

I hope you get it and enjoy it. What sport was that, again?

Hopefully they figure it out sooner rather than later.

Hockey! LOL!

I have two children who are hockey nuts. One is an LA Kings fan, the other is a Vegas Golden Knights fan. When the Knights came into existence, I decided that I had better get on the bandwagon or the day will come when my kids are talking together and I will have no clue.

So I prefer the Knights, because I spent so many years in Vegas, but when it’s appropriate, I’ll be a booster for the Kings. In fact, I gave my Favorite Son an LA Kings Build-A-Bear. It took me a year to afford the the bear AND the costume, but he got it for his birthday one year.

I like to watch football, but I played all sports that were available to me in school. This including horse riding and swimming, as well as hiking and ice skating. But I was good at softball, volleyball and basketball. And dancing!! ;o]

So, sports. Yeah. Although, if the hockey teams take a knee, that will end it for me...

Got any 7s?

Have you thought about moving us? We’re creeping up on 5,000 again, and I worry about taking up so much bandwidth. There should be some good candidates...

There was a pretty sad sack of an opus here about a week ago that I thought might be appropriate but the thread was pulled.
