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.

That’s a well-known jest.
I’ll go to Wallmart in the morning, because by the time I got to the bank, I was worn out. Only two stops before that, and I’m done.
To anyone in armadillo country, it probably is.
Everybody, sing!
Armadillo, Armadillo,
Softer than a rock,
Harder than a pillow.
Earliest sighting of cardinal...atop my snow covered stockade...beautiful contrast of the brilliant scarlet against the all w...hite background. (not easy getting innocuous common words into a thread without getting death threats from various alphabet groups)...gone before I reached the phone.
Congratulations! We have them year-round, but they starting singing early this year.
Three hours by Lancaster.
So about an hour and a half east.
Breathtaking! That looks like All Saints Bridge, though the figures are so small it’s hard to tell. No cars allowed on it.
Thanks, Moosie! (Homesick, now...)
I used to see Cardinals when I walked by St. Patrick’s Cathedral in NYC. None up here (so far).
Doubt I’ll ever see a NYC Cardinal sitting on my fence, the top rail is only a two by four...then again they’ve been known to straddle fences frequently.
;>)
Yep, zooming in one can see the projecting niches for the Saint’s statues even though the figures are too tiny to recognize.
The Bishop’s castle on the hilltop overlooking the plantation is a spectacular display of Baroque interior architecture. End of summer was a fine time to visit.
I loved that area so much. We lived in a town called Remligen, and it was so much fun to shop in. All of the best stuff with none of the tourist prices.
I’d love to go back, but my passport expired six years ago and I don’t think I’ll ever be able to save up enough gelt for a plane ticket!
It was quite a buclic idyll back in 1968...wonder what it’s like now.
Though in the town itself they were still reparing war damage.
Yes, I recall the scenes of war damage. We were there in 1970. We stayed in a beautiful old gässthaus on the side of a hill going out of town to Remlingen.
I never knew jet lag was such a hideous thing.
Nicest gässthaus I stayed in was at the foot of the towering Heidelburg Schloss...ancient inn within a walled cobblestone courtyard. First ever experience with a full goose down bed and coverlet...like sinking into a cloud...about a foot and half thick.
Ditto, that! My first ever taste of Mosel had me hooked, as well. I haven’t tasted anything so delicious since I left Germany.
Very scenic! I bet it’s haunted.
I dunno, but it had more than its share of castles to explore!
Smiled at the RAF Bomber Command
