Sentence examples for terranes from inspiring English sources

Relics of this process are incorporated into the Cordilleran mountain chain as discrete terranes that were accreted to the continent during or after the Devonian.

As these fragments reached the subduction zone, they were sutured onto the Cordilleran belt of North America, forming what geologists refer to as allochthonous terranes (fragments of crust displaced from their site of origin).

These terranes now make up much of southern Europe and parts of eastern North America.

These deposits formed accreted terranes (smaller landmasses subsequently added onto continents) that became attached to the margins of some continents during Mesozoic and Cenozoic times.

This process of "accretionary tectonics" (or obduction) created more than 50 terranes of various ages in the Cordilleran region, including the Sonomia and Golconda terranes of the northwestern United States, both of which were accreted in the Early Triassic.

The gold-producing Witwatersrand beds of South Africa may correspond to the terranes of western Queen Maud Land.

Orogenies may result from subduction, terrane accretion (landmass expansion due to its collision with other landmasses), the underthrusting of continents by oceanic plates, continental collisions, the overriding of oceanic ridges by continents, and other causes.

The collision of a terrane with the eastern edge of the continent during the Taconic orogeny caused the continental margin to flex and the sedimentary basin to deepen.
