The Chibanian age was named after Chiba, the Japanese prefecture where the sediment was found, and was recently ratified by the International Union of Geological Sciences. That period is important because it included the most recent reversal of Earth's magnetic field, an article in Eos said. At various points in our planet's history, Earth's magnetic north and south poles have swapped locations. When that flip happens, it leaves a mark in rocks around the planet. The cliffside sediment in Chiba, Japan, may offer a richer record of that reversal than any other site on Earth.
That polar flip, known as the Brunhes-Matuyama reversal, is still the subject of some debate. A 2014 paper published in the Geophysical Journal International used information from a layer of sediment found in Italy to argue that the flip took place in the span of a few decades. A 2019 paper published in the journal Science Advances argued, relying on information from ancient lava flows in Hawaii, that the reversal took closer to 22,000 years. As an excellent geologic record of this flip, the Chiba sediment could eventually help resolve the debate.
Studying how the polarity reversal happened might help us understand what's going on today. Our planet's magnetic poles have wandered in recent years, and scientists don't fully understand why.
Millions and Billions of years operate a framework of psychic distantiation from Human trauma in Antiquity - whose records are also our dramatic archetypal personae.
This is not to claim their are not 'millions of years ago' traces in the Record but that there is a joker in our pack, when evidences are ONLY evaluated through a limited Model of possibilities.
Why would the Bible associate its OT God of Terror with destroying or raising mountains? Because the survivors witnessed this. I am not referring to the Bible for Authority here - but indicating that it is part of a Record - regardless that all human records have signal and noise - and that discerning the true from the false is Within Us - and yet not as we image or conceive ourself and world to be.
