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.

In a recent discovery that could change how we understand Earth’s inner layers, scientists have found signs that precious metals like gold might be slowly leaking from the planet’s core. Until ...

Scientists discovered the true age of Earth's core, and it's older than they thought. Over the years, approximations for our planet's inner core have been all over the board, but most recently ...

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.

A ‘ghost plume’ identified deep in the mantle beneath Oman suggests there may be more heat flowing out of Earth’s core than previously thought ...

Mantle plumes are important geologic processes—they interact with plate tectonics, create rich mineral deposits, and even ...
