Earth’s core is leaking gold

Earth’s Core Leaks Precious Metals, Study Finds

The Earth’s core, contrary to conspiracy theories, is not hollow. It is a dense, hot ball that contains a variety of precious metals, including platinum, ruthenium, and gold. While accessing these treasures buried deep beneath the Earth’s surface seems impossible, recent discoveries made at volcanoes in Hawai’i suggest that trace amounts of these coveted metals are actually seeping up from the planet’s deepest reaches.

A team of researchers, led by Nils Messling from Göttingen University, made a groundbreaking discovery while analyzing volcanic rock samples collected across the islands of Hawai’i. They found trace amounts of the precious metal ruthenium, specifically the ruthenium isotope, ¹⁰⁰Ru, which is typically more abundant in the Earth’s core than in the mantle. This unexpected presence of ¹⁰⁰Ru in volcanic basalt samples indicates that material from the core, including precious metals like gold, is leaking into the Earth’s mantle.

The study, published in the journal Nature, reveals that the ruthenium found in Hawai’i’s volcanic rocks originated from near the core-mantle boundary. This discovery challenges previous beliefs about the inaccessibility of Earth’s core and sheds light on the inner dynamics of our planet.

The implications of this finding are significant. It suggests that the Earth’s core is not as isolated as once thought, and small amounts of core material are being ejected towards the surface during volcanic eruptions. This process, which was previously unknown, raises questions about the evolution of Earth’s inner dynamics and how it has shaped the planet over billions of years.

Researchers at Göttingen University developed new isotopic analysis methods that allowed them to differentiate between different forms of the same isotope, ultimately leading to this groundbreaking discovery. The study co-author, Matthias Wilbold, noted that huge volumes of super-heated mantle material, originating near the core-mantle boundary, rise to the Earth’s surface and form features like ocean islands.

The findings of this study open up a new perspective on Earth’s geological processes and the interactions between its core and mantle. It challenges our understanding of the planet’s deep interior and provides valuable insights into the dynamics that have shaped Earth’s surface over millions of years.

In conclusion, the discovery that Earth’s core leaks precious metals like ruthenium into the mantle through volcanic activity is a significant breakthrough in our understanding of the planet’s geology. It highlights the interconnectedness of Earth’s interior processes and raises new questions about the evolution of our planet. This study paves the way for further research into the dynamics of Earth’s core and its impact on the world we live in.
