A recent study investigated a 62-million-year-old lava flow on Baffin Island. arctic islands An abnormally high level of ~ has been revealed helium-3 (³He), a rare isotope associated with the internal structure of our planet.
This discovery raises the following interesting possibilities. earthPerhaps the core of leaking Helium-3 suggests a greater level of dynamism in Earth’s deep interior.
What perplexed scientists in the study was the unusually high levels of He found in olivine lava on Baffin Island. Earth’s mantle is not a static entity. It continually brings lava to the surface, consuming part of the Earth’s crust.
As a result, some of the He that had been stored within the Earth slowly leaked out over time.
However, scientists have established a limit to the amount of ‘He’ that can exist in mantle-derived rocks. Anything beyond this limit suggests alternative sources.
The logical implication is that rocks containing excess He could have originated deep within the Earth, perhaps from the core itself. The discovery challenges the traditional understanding that the planet’s core and outer layers, including the mantle and crust, are geochemically isolated, with minimal exchange of materials.
The discovery lends credence to the idea that matter, particularly helium, may be leaking from the Earth’s core, potentially reshaping our understanding of the Earth’s internal structure. It is something.
