Accretionary Orogenesis in the Active Continental Margins

Earth Science Frontiers, 2009
Abstract This paper reviews the research history and progress in the study of accretionary orogenesis, and concludes that accretionary orogenesis is the fundamental process of continental evolution throughout Earth's history. According to the authors' point of view, the formation and evolution of orogenic belts can be explained by the evolution of ...

Crustal growth at active continental margins: Numerical modeling

Physics of the Earth and Planetary Interiors, 2012
The dynamics and melt sources for crustal growth at active continental margins are analyzed by using a2D coupled petrological–thermomechanical numerical model of an oceanic-continental subduction zone.This model includes spontaneous slab retreat and bending, dehydration of subducted crust, aqueous fluidtransport, partial melting, melt extraction and ...

Active continental margins

2007
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

2010
Subduction 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.

Electromagnetic study of the active continental margin in northern Chile

Physics of the Earth and Planetary Interiors, 1997
Magnetotelluric and geomagnetic deep sounding measurements were carried out in the magmatic arc and forearc regions of northern Chile between 19.5° and 22°S to study the electrical conductivity structures of this active continental margin. The instruments used covered a very broad period range from 10−4 s to approx.

Turbidite paleoseismology along the active continental margin of Chile - Feasible or not?

Quaternary Science Reviews, 2015
Much progress has been made in estimating recurrence intervals of great and giant subduction earthquakes using terrestrial, lacustrine, and marine paleoseismic archives. Recent detailed records suggest these earthquakes may have variable recurrence periods and magnitudes forming supercycles.

Active deformation of the Pacific Northwest Continental Margin

Tectonics, 1984
Tilted 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 ×

Four‐dimensional numerical modeling of crustal growth at active continental margins

Journal of Geophysical Research: Solid Earth, 2013
AbstractCrustal growth and topography development in subduction‐related arcs are intimately related to magmatic processes and melt production above subducting slabs. Lateral and temporal variations in crustal thickness and composition have been observed in nature, but until now no integrated approach has been developed to comprehensively understand ...
