New Research Suggests That Earth’s Core Is “Leaking” Gold Along With Other Precious Metals

Earth’s core is full of various metals such as nickel and iron, and its inner layer is made up of solid materials, while the outer layer is in liquid form. Despite the high temperatures, it has remained solid because of the extreme gravitational pressure at the center.

The new study suggested that those metals from the outer layers of the core that are in a liquid form because of the high temperature without enough pressure are currently leaking to the surface. Some of the metals that have been observed are gold and platinum. Let’s discuss where and how scientists detected it.

Precious Metals Rising from the Deep

A recent study published in Nature reveals that the Earth’s core is leaking gold and other precious materials into the mantle and has the potential to reach the surface. The other materials are all in the platinum group, such as ruthenium. This simply means that they are highly valued, and if this leak reaches the surface, people would be racing to mine it.

They have done this study by analyzing the volcanic rocks from Hawaii, particularly basalts from Kīlauea. Researchers found that a specific isotope of ruthenium is present in these rocks. One that should have only existed deep in our Earth’s core, suggesting that the mantle already contains leakage of metals from the center of the Earth, and is likely to carry it forward to the crust.

Challenging Earth’s Geochemical Isolation

Earth's core holds a vast reservoir of gold - and it's leaking towards the surface

So, what does this imply about our understanding of the Earth? For decades, scientists assumed the core is sealed off because of the extreme pressure and temperature at the center, and that a leak could not occur. This new study highlights that we are wrong and that the core is more connected to the mantle and the crust than we previously estimated.

The detection of these ruthenium isotopes that should have only been present at the Earth’s core challenges our understanding. The fact that they are in rocks from lava on the surface of the Earth means that the leakage of these metals are already on ongoing for countless years without us realizing it.

Implications for Resource Distribution

It is also a study that highlights why the distribution of certain precious metals is concentrated in particular geological locations, such as Hawaii. The mantle plumes, based on the leakage from the core, have probably carried them over in those places.

Scientists think that if these metals have continued to flow slowly over time, some of the Gold and metals we have already mined are probably from the Earth’s core. How cool is it to think that some of the gold from our watches, jewelry, and even cell phones could be from the center of the planet?

A New Window into Earth’s Dynamics

Beyond just future planning on when to prepare mining fields to get more Gold and other precious materials, this study also gives us new insights into how our world works. It suggests that our core is connected more than we realized to the mantle and the crust, and that material exchange occurs even at the deepest layers of the planet.

This will give us more accurate data and expectations on volcanic island formation, the appearance of rare Earth minerals, and the overall evolution of the Earth over time. The future may be filled with even more gold than today.

GOLD Is Pouring Out of Earth's Core?!

Author's Final Thoughts

Earth’s core is not as isolated as we thought, and it could exchange materials with the mantle and eventually the crust. It could also leak precious materials that our civilization values highly. A reminder that the planet holds more secrets than the acquired knowledge we have about it.
