Earth's magnetic field plays a key role in protecting life on our planet. Yet its origin and evolution remain subjects of ...

Unlike the core, the mantle is mostly solid, and makes up most of the planet (84 percent of the Earth’s volume to be exact). Comparatively, the mantle also has less of a platinum-group-metal ...

Researchers have found evidence that Earth's core is leaking gold and other precious metals, according to a new study. The vast majority (99.9%) of Earth's gold and other precious metals are ...

Although more than 99.95% of Earth's gold is locked in the molten core, tiny amounts may be coming up to the surface in magma, a study found. A lava fountain at Kilauea in Hawaii is seen in early May.

While ¹⁰⁰Ru does exist in Earth’s mantle, it’s slightly more abundant inside of the core —alongside 99.999 percent of the planet’s gold and other precious metals.

Well, ruthenium does exist on the Earth’s surface – but, like gold, it’s far more abundant within the core. 100 Ru specifically is even more traceable: “the Ru isotope composition of ...
