In contrast, the inner trench wall is deformed by plate interactions for the entire life of the convergent margin.

It has been estimated that convergent margins may contain up to two-thirds of the total gas hydrate volume on the earth (Kastner, 2001).

The North Andean convergent margin is a region of large crustal deformation.

Some convergent margins have zones of active seafloor spreading behind the island arc, known as back-arc basins.

So far we have confined our attention to convergent margins where two plates are in motion towards each other.

Subducting plates can bring island arcs and sediments to convergent margins.

The evolution of the IBM arc system is among the best known of any convergent margin.

This is an oversimplification, because different parts of a convergent margin can experience sediment accretion and subduction erosion over its life.

Non-accretionary convergent margins are characteristic of (but not limited to) primitive arc systems.

Not all non-accretionary convergent margins are associated with primitive arcs.
