Earth is missing a huge part of its crust. Now we may know why. A fifth of Earth’s geologic history might have vanished because planet-wide glaciers buried the evidence.

Earth's crust today has a surprisingly similar composition to the planet's first outer shell, or "protocrust," new research finds. This early rocky shell featured chemical signatures previously ...

Some areas of continental crust have maintained long-term stability from the beginning of Earth's history, with little destruction by tectonic events or mantle convection, known as cratons.
