Earth's core has been leaking for billions of years

Earth's magnetic field protects and makes our planet habitable by stopping harmful high-energy particles from space, including from the Sun. The source of this magnetic field is the core at the centre of our planet.

Why is the Earth's F/Cl ratio not chondritic?

Primitive chondrites, un-molten stony meteorites, are believed to be the building blocks of the Earth. Because terrestrial planets have experienced chemical differentiation in the core, mantle, and hydrosphere, the elemental ...

Magnetism discovered in the Earth's mantle

The huge magnetic field which surrounds the Earth, protecting it from radiation and charged particles from space—and which many animals even use for orientation purposes—is changing constantly, which is why geoscientists ...

Cool Earth theory sheds more light on diamonds

A QUT geologist has published a new theory on the thermal evolution of Earth billions of years ago that explains why diamonds have formed as precious gemstones rather than just lumps of common graphite.

Earth's deep mantle flows dynamically

As ancient ocean floors plunge over 1,000 km into the Earth's deep interior, they cause hot rock in the lower mantle to flow much more dynamically than previously thought, finds a new UCL-led study.
