At the MOR, molten rock is carried upward towards the surface via convection, where new oceanic lithosphere is generated (usually as an fine-grained igneous rock known as basalt) and the plates are further pushed away from the spreading center.
The crystallized magma forms new crust of basalt (known as MORB for mid-ocean ridge basalt) and gabbro. They are formed by two oceanic plates moving away from each other. The rocks making up the crust below the seafloor are youngest at the axis of the ridge and age with increasing distance from that axis.
