Scientists have found a key indicator in determining whether the presence of carbon, found in the Earth's mantle, is derived from continental crust - a step toward better understanding the history of crustal formation on Earth's surface and the rate at which tectonic plates have moved throughout geologic time, which can be linked to the cooling of Earth's mantle.
