Dutch Scientists⁢ Discover Two‍ Ancient Mountains Far​ Taller Than Mount Everest

In a groundbreaking ⁢discovery,⁣ Dutch scientists have⁤ identified two colossal mountains deep within the Earth’s ‍interior, dwarfing the height of Mount Everest. These subterranean giants, located at ‍the boundary between the Earth’s core and mantle, may be billions of years⁤ old,‍ challenging‍ our understanding of the planet’s geological history.

The research, led by Dr. ​Arwen ⁣Deuss, a seismologist and professor at utrecht University, was published in the prestigious journal Nature. “No one knows ‌what it is, and whether it is only a temporary phenomenon, or whether they have been there for ‌millions or even ​billions of‍ years,” ‌Dr. Deuss explained.

The discovery of‍ the ⁢Super Mountains

The two mountains, ‍referred to ‌as Large Low Seismic Velocity Provinces (LLSVP),⁢ are ⁣located beneath Africa and ‌the Pacific Ocean. They are estimated ‍to be​ 100 times taller than mount Everest, which stands ​at 8,849 meters. These structures are surrounded by a “large grave” of​ tectonic plates, formed‌ through ‍the process of‍ subduction, where one plate ​slides​ beneath another and sinks into ​the Earth’s‌ interior.⁣

“This mountain is⁤ also ⁢surrounded ​by ‌a ⁤‘large ⁣grave’ of a tectonic⁤ plate that has shifted there because of the subduction process, which is when ⁤one tectonic plate swoops under the other plates and ‍sinks from the surface of the earth to a depth of almost​ 3,000 km,” Dr. ⁤Deuss said.

Mapping ⁢the Earth’s Interior

Scientists have⁣ long⁣ known‍ about these formations ‌due to seismic ‍waves generated by earthquakes. These⁣ waves ‍travel through the Earth’s interior, revealing anomalies like the LLSVP.“We see seismic waves slowing there,” Dr.⁣ Deuss noted,​ describing how the‍ waves behave​ when encountering these massive structures.

The research team discovered ‌that these mountains are not ‌only hotter than the surrounding tectonic plates but also potentially half a billion years older. This finding contradicts the‌ previous assumption that the earth’s mantle is well-mixed and flows rapidly.

The Mystery of⁢ Seismic Wave Damping

One of the most ⁢intriguing aspects of ‌the study is the behavior of seismic waves in these regions.‍ Sujania talavera-Soza, a⁣ researcher‍ involved in the study, explained, “In contrast⁢ to ‍our ⁣expectations, we ⁤found a little damping on⁤ LLSVP,​ which made the tone sound very loud there. Though,‌ we found​ a lot⁢ of‌ damping in the grave of the cold plate, which‍ made the tone sound⁤ very soft.”

Talavera-Soza likened this phenomenon to running in hot weather:⁢ “You not only slow down, but also become ⁢more tired than when cold weather outside.”

Implications for Earth’s⁤ Geological History⁤

This discovery⁢ challenges existing theories about the Earth’s interior dynamics. The presence of these ancient mountains suggests that the mantle⁢ may be less‌ fluid⁤ and more complex than ⁣previously thought.

| Key Findings | Details |
|——————-|————-| ⁢
| Location ⁢ | Beneath Africa and the Pacific ocean | ⁢
| Height ⁢ | 100 times taller than Mount Everest |⁢
| ⁢Age ​ | Potentially billions of years old |
| Seismic Behavior | ⁣Waves slow down and exhibit unique damping patterns |

A New Chapter in Earth science

The findings⁤ open up new ​avenues for⁢ understanding the Earth’s ⁤geological evolution. As Dr. Deuss and her‍ team continue to analyze these structures, they hope⁤ to uncover more about the planet’s ancient past and the forces that shaped it.
