The Secret Behind Gold & Platinum in Earth’s Mantle?

Southwest Research Institute’s Dr. Simone Marchi collaborated on a new study finding the first geophysically plausible scenario to explain the abundance of certain precious metals — including gold and platinum — in the Earth’s mantle. Based on these simulations, scientists found an impact-driven mixing of mantle materials scenarios that could prevent the metals from completely sinking into the Earth’s core.
