deepest hole ever drilled, the Kola Deep borehole in the Russian Arctic, reaches only 0.2 percent the way to the center...even the best scientific maps didn’t look much better than your middle-school textbook cartoon showing an outer crust, an inner core and a thick layer called the mantle in between But that picture is changing. Researchers... are...seeing is full of complex detail...The mantle appears to be layered like an onion, with major transitions 250 miles and 410 miles down. At the 410-mile level, researchers recently identified a tremendous interior mountain range, with peaks perhaps even taller than Mount Everest. “ [end of 100 word excerpt for those who only read the lead]
Researchers such as Barbara Romanowicz at the University of California, Berkeley are using seismic (earthquake) waves to scan our planet’s innards, much like doctors use ultrasound to peer inside patients...
“Recently, we’ve discovered another change at about 1,000 kilometers [600 miles] depth,” Romanowicz [at the University of California, Berkeley] says. The layers are riven by rising plumes of hot rock. And beneath the plumes, two strange blobs roughly the size of Australia bob atop the core, one beneath Africa and one under the Pacific Ocean.
“More and more, we’re understanding it’s not the standard cartoon picture,” Romanowicz says. “For geodynamicists, it’s a complete revolution.”...
mantle blobs are of special interest because of their impact on life on the surface...and those plumes can trigger devastating supervolcanic eruptions when they surface..and those plumes can trigger devastating supervolcanic eruptions when they surface...that unleashed a wave of eruptions in what is now India...Other plumes led to massive volcanoes that created Iceland and which continue to drive the rumbling activity beneath Yellowstone... . ...this approach cannot easily distinguish warm, dense material from cooler, lighter stuff. That leaves a lot of room for interpretation.

There’s a lot of way more wierd blobs in D.C. Check out the White House staff and a good number of the Child Sniffer/Daughter Molester’s picks for top positions. (You listinin’ ‘Admiral’ whatever?)
One of my favorite movies as a kid was “Journey To the Center Of the Earth,” which came out in 1959. That and “20,000 Leagues Under the Sea.” Both films starred James Mason.
Many thanks for the article d12. Much appreciated.
It’s turtles - all the way down.
Wait! What?
“... climate changes ... over the past few hundred million years,”????

There is nothing like imaging with ever increasing resolution to advance Real Science.
One day there will be a profound revaluation of dating.
That ConeHead woman’s luggage thief is prime and in center.
Many things is science are “onion-like” in that the more research done in some area may answer some question but reveals new facts that defy old understandings and present new questions not even on our radar before.
Thank you very much, Daniel!
Didn’t Pat Boone star in one of them?
I look forward with great anticipation to spending an eternity trying to comprehend how great our God and how majestic His creation. He is more wonderful than we will be able to fully know even given an eternity to discover!
Note that this has the wokekeeping seal of approval, due to all the named researchers being female (biological we assume), and presumption of accurate billion years dating, and absence of any inference of a Creator, though it provides implicit confirmation of the Bible.
“Didn’t Pat Boone star in one of them?”
Yes, “Journey To the Center Of the Earth.”
