For 60 years, scientists have tried to get rock samples of the Earth’s mantle. But the geologic layer below the planet’s crust is incredibly difficult to reach.
Scientists believe they’ve successfully exhumed a 1,000-kilometer core sample that reaches into the very edge of the mantle.
Examining this rock could help scientists understand magma flows, earthquakes, and other geologic mysteries.
To understand the geologic processes roiling beneath the Earth’s crust, it helps to have samples of what exactly is going on down there.
