How does the age of the oldest continental crust compare to the age of the oldest ocean crust
🔄 Click to see definition
Definition1/14
The oldest continental crust would be between three and one half
to four billion years older than the oldest oceanic crust. This is
due to the fact that ocean plates are subducted under the
continental plates, subjected to partial melt and essentially
recycled in the mantle before reforming.
