If they continue, continental rifts will eventually become oceanic rifts.
2.
This was deposited as limestone in a Precambrian oceanic rift trough.
3.
Another type of volcanic oceanic island occurs where an oceanic rift reaches the surface.
4.
Axial propagation of the oceanic rift occurs, resulting in a continuous axis of spreading.
5.
The rift transitioned from a continental rift to an oceanic rift . Magnetic anomalies suggest that the spreading rate on either side of the Red Sea is about 1 cm / yr.
