Unlike most subduction zones worldwide, no oceanic trench is present along the continental margin in Cascadia earthquake of 1700.
32.
During Late Carboniferous there was a continental margin with an oceanic trench subducting the ocean floor off the coast.
33.
Over time, plate tectonics moved this amalgamation of crust generally northeastward into contact with the North American continental margin.
34.
The other side of the basin is bounded by the Cameroon Volcanic Line and the transform passive continental margin.
35.
Active continental margins have narrow, relatively steep shelves, due to frequent earthquakes that move sediment to the deep sea.
36.
While continental margins are typically the most deformed in orogenic events, the interior of continental plates can also deform.
37.
This implies formation at the continental margin, and then rifting, in the manner of the second class of models.
38.
Transform faults are not limited to oceanic crust and spreading centers; many transform faults are located on continental margins.
39.
First, the passive margin stage with orogenic loading of previously stretched continental margin during the early stages of convergence.
40.
This indicated that there was still insufficient knowledge about transport processes and biological turnover of organic carbon along continental margins.
