Tectonic models for the formation of arc-shaped convergent zones and backarc basins

Schellart, Wouter; Lister, Gordon


Four popular tectonic models are discussed that attempt to explain the formation of arc-backarc systems. These systems develop in a convergent setting with shortening in the forearc region, extension in the backarc region, and progressive out-bowing of the arc. The models include the gravitational collapse model, the rollback model, the extrusion tectonics model, and the orogen-parallel compression model. The rollback model can explain the progressive development of most arcs, such as those...[Show more]
