Active and passive continental margins

Active margins are commonly the sites of tectonic activity earthquakes, volcanoes, mountain building, and the formation of new igneous rock. Because of the mountainous terrain, most of the rivers are fairly short, and the continental shelf is narrow to non-existent, dropping off quickly into the depths of the subduction trench.

Natural sedimentation rates at similar along-canyon distance from shore in the untrawled continental slope (9001500 m) and in the lower canyon axis (15002200 m) are comparable (0.080.20 cmyr −1), suggesting distance from coastal sediment sources as the main control on regional sedimentation in deeper parts of the margin.

Abstract Recent research on the Mississippi margin indicates notable seasonal variation in seabed dynamics. During years with minimal tropical-system activity, sediments initially deposited from late spring to early fall are remobilized by wind-driven currents and wave energy during extra-tropical weather systems in the winter.

Note on this diagram the sediments at the continental margin are shown as not very thick. This is because the model is based on the East African Rift System, which does not have a great deal of subsidence associated with rifting. However, other rifted continental margin sequences are very different, with thick sedimentary sequences.
