Geologists Discover New Layer in Earth’s Mantle

New research led by Dr Hauke Marquardt of the University of Bayreuth, Germany, suggests the existence of a previously unknown superviscous layer inside our planet: part of the lower mantle where the rock gets 3 times stiffer. Such a layer may explain why tectonic plate slabs seem to pool at 930 miles (1,500 km) under Indonesia and South America’s Pacific coast.

“The Earth has many layers, like an onion. Most layers are defined by the minerals that are present. Essentially, we have discovered a new layer in the Earth. This layer isn’t defined by the minerals present, but by the strength of these minerals,” said Dr Lowell Miyagi of the University of Utah, the second author on the paper published in the journal Nature Geoscience.

There was some discussion following the recent big earthquake in Chili about how there could be earthquakes below the crust in the upper mantle and even below the lithosphere. This study is of changes or increases in viscosity in different areas of the mantle and in some spots very near the core. This study looks at a region below the subduction zones at and near the diving Pacific Plate. High viscosity regions are so resistant to flow that they can fracture under great pressure giving very deep earthquakes. This may be effected by deep areas of viscous mineral below the subducting Pacific plate and at the outer core.

This is impossible. We know everything about the planet and without any doubt whatsoever can conclude things like global warming is real. /sarcasm

This article is wrong. The science was settled, there was consensus...

“The Earth has many layers, like an onion.”

Just like Ogres.

Seriously, we need to visit the core. Send a probe at least... since I was a kid I’ve been fascinated with that thought.

Non-Newtonian fluid? Like Silly Putty? That would explain everything!

Silly putty LOL.

But if the earth has layers like a candy bar, it explains all of the nuts on the outside.

Maybe Stahlman’s gas for cheap abundant energy will be found after all.

Lol!
I remeber reading a book by John Brunner, in which the police had something called “Caratands.” They were soft until you hit someone, and they turned rock hard. Silly putty in special gloves could do this! Normal hand movements , no problem. But smack someone and it’s like hitting them with a brick! Maybe I need to make a pair for my next trip to Cleveland?

Karatand;

...a Karatand... It was in effect a palmless glove made of impact-sensitive plastic about a quarter-inch thick. Pressed, pinched, drawn on or off the hand, it remained flexible and nearly as soft as good leather. Struck against a resistant surface, its behavior changed magically, and while the interior stayed soft to act as a cushion against bruising, its outer layers became as rigid as metal.
He thrust his fingers into it and spun around, slamming his fist at the wall. There was a solid thud, and the muscles of his upper arm and shoulder complained, but the Karatand reacted as designed. It was several seconds before he could straighten his fingers against the resistance of the relaxing plastic.”

““This viscosity increase is likely to cause subducting slabs to get stuck at about 930 miles underground,” Dr Miyagi said.”

Is that what finally happened to poor John? His slab got stuck?

Reptilian ValJar is an Islamic Jinn from deep beneath the earth’s crust.

They’re calling it below the lower mantle. Even viscous rock that far down is not compressible. Any force would redirect upward. Definitely something going on down there.
