Origin and dynamics of depositionary subduction margins
Paola Vannucchi, Jason P. Morgan, Eli Silver, Jared W. Kluesner
2016, Geochemistry, Geophysics, Geosystems (17) 1966-1974
Here we propose a new framework for forearc evolution that focuses on the potential feedbacks between subduction tectonics, sedimentation, and geomorphology that take place during an extreme event of subduction erosion. These feedbacks can lead to the creation of a “depositionary forearc,” a forearc structure that extends the...
