Recent Examples of craton from the Web
But unlike other cratons, East Antarctica didn’t seem to experience much in the way of seismic activity.
This section of the continent is known as a shield or craton, a very old and stable portion of the continental crust.
There are some found outside those cratons (such as the kimberlites of Kentucky and Arkansas) but they are still typically found where the rocks are old.
Most kimberlites are found in areas of the oldest rocks on Earth known as continental cratons.
