The scientists then focused on ruthenium, a silver-gray metal about as rare in Earth’s crust as gold. “The mantle has almost no ruthenium in it,” Messling said.

An analysis of Hawaii’s volcanic rocks revealed Earth’s core is leaking gold and other precious metals, a study found. The elements emerge when ocean islands form.
