rifting

The breaking up or rifting was not a process that happened along one clear line.

These were therefore probably closest to the main line of plate rifting.

The rifting stopped before the land could become two separate continents.

(The cause and nature of the rifting does not seem to have been worked out yet.

This was the first phase of rifting between Europe and Africa.

Low temperatures may have been exaggerated during the early stages of continental rifting.

How this affects the postulated rifting does not seem to have been addressed.

The pattern in north-west Europe was now very much one of tension and rifting.

The plants at least only showed significant changes with the rifting of the plates in later Triassic times.

These sediments are interpreted to have been deposited during a period of rifting.

It has been suggested that these granites formed associated with rifting.

When the rifting began, dinosaurs could walk from Virginia to Africa in a matter of days.

But the boundary continues south of the zone, where there is no evidence of rifting.

Magmatic activity and rifting may also be independent events.

The ocean basins are created by the rifting apart of continents.

Another unsuccessful attempt at rifting 200 million years ago created additional faults, which made the area weaker.

The upwelling of asthenosphere is not involved in the actual rifting process.

Uplift associated with the rifting altered the connections among the region's water bodies.

The most active rifting and associated volcanism came to an end in the late Cenozoic.

Hotspot tracks and the early rifting of the Atlantic.

Some rifts show a complex and prolonged history of rifting, with several distinct phases.

Only after initial rifting does any mantle melting occur.

Afterwards, subsequent rifting produced large fault-block mountains throughout the region.

To the north is a mixture of very thin sea ice, ice blocks from earlier rifting, and open water.

The Rodinia hypothesis assumes that rifting did not start everywhere simultaneously.
