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.

Driving to Walmart in the dark, in the rain is always an adventure. The white lines to the sides of the pavement, a thing for which Utah should be proud, disappear in the rain. I followed another car, not so closely that I’d be in trouble if it was, but close enough to know where the road was.

One thing is for sure: the wipers got an excellent workout!

Now, I’m going to sort the pills and start my day. If I can. I’m not nearly as agile now as I was before I left for Walmart, so anything that takes a large range of motion will have to wait a bit.

We’re about to hit the road. I’ll check in by some means before the end of the day local time.

Safe journey, and watch out for the Other Guy!

Driving to Walmart: It’s not just a chore, it’s an adventure.

It sure is in this part of the country! I’ll miss that drive for sure. I’ve loved every minute of living here because the scenery is what I grew up with.

Our cats NEVER go outside, except on the screen porch. They started life as ferals, and probably don’t miss that lifestyle. It took a while for them even to venture on to the screen porch.

We are arrived and set up. Kathleen wants to sleep in a tent by herself. We’ll see how it goes.

We are near Raleigh airport, but we will soon stop noticing it.

I’m glad I checked! LOL!

Have fun! The good thing about airports is that traffic slows down at night. In Vegas the planes come in every four minutes as opposed to every two minutes during the day!

Take care and have a good night!

Good morning. The planes aren’t bad. People in the next campsite were watching tv, which was obnoxious, but they left already this morning.

The male family members are finding that they didn’t pack everything on the list. Oh, well.

When we were camp hosts, we had a generator, a TV and a VCR/player. But the RV was our “home,” and the host site usually had running water, and in some cases, power and once in a while, a septic tank. If the power wasn’t supplied, the forest service provided gasoline for the generator and for doing the patrols. The shortest time we were at any campground was five months.

But to go camping and take a TV? That rather defeats the purpose, as far as I’m concerned!

The rain finally stopped, but the most we got out of the storm(s) was less than a quarter of an inch. Now, of course, we have the wind. Always with the wind.

I have no clue what will happen on today’s blank agenda, but something may. Someone may even commit a box-packing event. Gloriosky! Think about it!

In other news, I was able to pack a few more things and get Some Things into boxes to be filled with Other Things, later. I’m trying to keep it logical, of course, so I’m not met with the traditional, “What in the world is this doing in HERE?” when I start to unpack.

So, I’m going to take a break for a bit and then get three more boxes done. Making a total of 43! (Forty-five if you count the two in progress! Mostly books left and a little bit of kitchen/pantry stuff.

Slowly, slowly, catchee monkey. So the Brits say, in numerous series episodes! More stuff to donate, as well!!

Mrs. ArGee is still trying to find the refrigerator magnet that holds the hot pads. “I decided I could just put it in a box this time and I didn’t need to mark it. That’s what I get.”

I empathize!

THAT problem I’ve taken care of by listing the box contents in a notebook. Box #, Contents, Room (L,K,BR,BA.) It has simplified at least two moves and will make this one much better!

Some things are in storage tubs, but those contain soft items, like linens and yarns/fabrics. No need to label them.

It’s that time of day again, and for some odd reason, I’m a little tired, so I’ll head down the hallway and call this a day.

See y’all tomorrow! ;o]
