Through much of the earth's history, they believe, continental fragments have been tossed back and forth, sometimes traveling several thousand miles.

Later its continental fragments were re-assembled to form Pangaea 300-250 million years ago.

Several islands in the eastern Indonesian archipelago are considered continental fragments, although this is a controversial theory.

These are essentially continental fragments whose boundaries are generally defined by faults.

At this point basaltic oceanic crust begins to form between the separating continental fragments.

Continental fragments include some seamounts and underwater plateaus.

As a cultural construct, the concept of a continent may go beyond the continental shelf to include oceanic islands and continental fragments.

All continents are fragments; the terms 'continental fragment' and 'microcontinent' are restricted to those smaller than Australia.

Prevailing opinion holds that the archipelago represents the non-submerged regions of the continental fragment known as Zealandia.

Continental fragments correspond to land masses that have separated from a continental mass due to tectonic displacement.

Blake speculates that the rocks were probably the upper edge of a continental fragment that plunged under the North American plate.

Continental fragments (pieces of Pangaea smaller than Sahul)

Paleomagnetism continues to extend the history of plate tectonics back in time and are applied to the movement of continental fragments, or terranes.

There are many microcontinents, or continental fragments, that are built of continental crust but do not contain a craton.

The edges of continental fragments formed this way (both sides of the Atlantic Ocean, for example) are termed passive margins.

Terranes are smaller pieces of continental crust that have been caught up in an orogeny, such as continental fragments or island arcs.

Rodinia is hypothesised to have broken up in the Neoproterozoic with its continental fragments re-assembled to form Pannotia 600-550 million years ago.

The rocks of the Klamath Mountains originated as island arcs and continental fragments in the Pacific Ocean.

The Acadian orogeny involved the collision of a series of Avalonian continental fragments with the Laurasian continent.

A continental fragment may have collided with the area, pushing off the Hastings Block and fracturing the Barnard Basin.

Volcanism on Zealandia has also taken place repeatedly in various parts of the continental fragment before, during and after it rifted away from the supercontinent Gondwana.

Farther south the Winnipeg River and Marmion terranes are relatively small continental fragments dating back to 3.4 and 3.0 Ga, respectively.

The rift in its turn evolved into a mid-oceanic ridge that separated small continental fragments such as Avalonia and Carolina from the main Gondwanan land mass.

Depending on their geological origin, islands forming archipelagos can be referred to as oceanic islands, continental fragments, and continental islands.

These accretion events occurred in several phases, probably by accretion of continental fragments separated by pauses in subduction, with renewed activity occurring episodically.
