IN A NUTSHELL |

In a groundbreaking discovery that could revolutionize our understanding of the Earth’s inner structure, scientists have identified colossal mountain formations hidden deep beneath the Earth’s surface. These structures, which dwarf Mount Everest by over 100 times, have the potential to significantly alter how we perceive geology and the planet’s history. This finding provides a new lens through which to view the Earth’s depths, challenging long-standing theories and offering fresh insights into our planet’s complex geological makeup.
The Awe-Inspiring Depths
Scientists have located two colossal mountains at a remarkable depth of 1,200 miles beneath the Earth’s crust. Each of these mountains is approximately 620 miles high, making them more than 100 times taller than Mount Everest. These enormous structures are situated beneath Africa and the Pacific Ocean and are referred to as “Large Low-Shear Velocity Provinces” (LLSVPs).
The LLSVPs are believed to consist of dense, ancient materials, potentially remnants of ancient tectonic plates. These formations are similar to recently discovered submerged geological structures and have been stable for over 4 billion years. This challenges the notion that the Earth’s mantle is a constantly shifting layer, akin to the changes observed in the rotation of the Earth’s inner core.
Seismic Waves Reveal Hidden Secrets
A recent study published in Nature utilized seismic waves generated by major earthquakes to uncover these massive structures. As these waves traverse zones of varying density, they slow down, allowing scientists to detect the LLSVPs. The study relies heavily on seismic tomographic models, which use wave velocity to describe the Earth’s interior, though these models have certain limitations.
To enhance the analysis, researchers developed a new global 3D attenuation model. This model leverages oscillations that travel through the entire Earth to constrain spherical harmonics up to the fourth degree. In the upper mantle, strong attenuation linked to reduced velocity suggests a thermal origin, whereas in the lower mantle, the relationship is inverse. The LLSVPs are not only ancient and stable compared to the rest of the mantle, but they are also hotter than their immediate surroundings. This discovery casts doubt on several theories about the Earth’s internal structure and could pave the way for new insights into its geological past.
Comparative Analysis and Implications
By comparing current models with a viscoelastic model created in the lab, researchers observed that the circum-Pacific region is colder with a smaller grain size, while the LLSVPs are hotter and have a larger grain size. The calculated viscosity values confirm that these deep mantle provinces are stable and enduring entities. This comparative analysis is crucial as it highlights the distinct characteristics of these formations and their potential impact on our understanding of the Earth’s geological evolution.
The implications of these findings are profound, suggesting that the Earth’s mantle is more complex and varied than previously thought. The LLSVPs could provide new insights into the dynamics of plate tectonics and the history of continental drift. As scientists continue to explore these hidden giants, they may uncover further evidence that reshapes our understanding of Earth’s geological processes.
The Future of Geological Research
This discovery opens up exciting new avenues for geological research. By studying these massive formations, scientists hope to gain a clearer picture of the Earth’s internal dynamics and its impact on surface phenomena like earthquakes and volcanic eruptions. The stability and age of the LLSVPs may also offer clues about the Earth’s early history and the processes that shaped its current structure.
As researchers delve deeper into the mysteries of these subterranean mountains, they may unravel secrets that have long eluded geologists. The potential applications of this knowledge are vast, from improving our understanding of natural disasters to informing the search for similar structures on other planets. This discovery raises intriguing questions about what else might be hidden beneath our feet, waiting to be uncovered. What other secrets does the Earth’s mantle hold, and how might they transform our understanding of the planet we call home?

Wow, 100 times taller than Everest? That’s mind-blowing! 🌋
Sorry to break it to you, but this Is likely AI generated. None of this could be true as I had not found any other news articles suggesting this post.
Are these mountains made of the same materials as those on the surface?
Incredible discovery! Thanks for sharing this fascinating information.
Does this mean we have to rewrite all the geology textbooks now? 🤔
How did scientists manage to measure these mountains so deep underground?
Could these structures affect earthquake activity?
Sounds like something out of a sci-fi movie! 🚀
Is it possible to visit these underground mountains someday?
Wait, how do we know they’re stable if they’re so ancient?
