In Chapter 6 we considered the simplest type of subduction-related magmatism produced as a consequence of the subduction of one oceanic plate beneath another. Now we shall focus our attention on the more complex case in which the overriding plate is a continental one.

Subduction Zones, Island Arcs and Active Continental Margins
2010Subduction zones are created when two lithospheric plates move against each other and one of the two plates descends under the other through the process of subduction. However, only oceanic lithosphere is able to sink deeply into the Earth’s mantle to become reincorporated there.

Neotectonic Activity of Atlantic Inner Continental Margin: ABSTRACT
AAPG Bulletin, 1981A consistent pattern of neotectonic activity along the inner edge of the Atlantic continental margin is emerging from new data on earthquake activity, contemporary vertical movement and geologic structure. Seismic activity, as shown by both historic and instrumental data, is concentrated in embayments on the Atlantic coastal margin.

Geomorphology, 2014
Abstract The Palomares Margin, an NNE–SSW segment of the South Iberian Margin located between the Alboran and the Algerian–Balearic basins, is dissected by two major submarine canyon systems: the Gata (in the South) and the Alias–Almanzora (in the North). New swath bathymetry, side-scan sonar images, accompanied by 5 kHz and TOPAS subbottom profiles,

Active Continental Margins and Island Arcs
1974Certain regions of the earth are characterized by unusually high geophysical and geological activity, exemplified by deep earthquakes, volcanism, and mountain building. These regions form two fairly continuous belts, one around the Pacific Ocean (Fig. 1), the other extending through Asia to the Mediterranean Ocean.

Active Continental Margins: Contrasts Between California and New Zealand
1974The margins of the Pacific Ocean in both California and New Zealand each contains two parallel terranes similar in age but very different in lithology, structure, and metamorphic mineral assemblages. In California, the structurally lower terrane is the Franciscan assemblage, deposited in deep marine environments and made up of rarely fossiliferous ...

Active deformation of the Pacific Northwest Continental Margin
Tectonics, 1984Tilted and uplifted marine terraces in southern Oregon show progressive landward tilting of the coastal ranges at about 5–16 × 10−8 rad. yr−1 for the last 0.25 m.y. Tide gauges in Washington and British Columbia, and ten resurveyed leveling lines running inland from the coast, indicate contemporary landward (down‐to‐the‐east) tilt rates of about 1–12 ×

Tectonophysics, 1981
Abstract Subduction zones with deep seismicity are believed to be associated with the descending branches of convective flows in the mantle and are subordinated to them. Therefore, the position of subduction zones can be considered as relatively fixed with respect to the steady-state system of convective flows.
