The effect of low-viscosity sediments on the dynamics and accretionary style of subduction margins

Abstract:

Observations of sediments at subduction margins appear to divide them into two classes: Accretionary and erosive. Accretionary margins are dominated by accretion of thick piles of sediments (>1 km) from the subducting plate, while tectonic erosion is favored in regions with little or no sedimentary cover (<1 km). The consequences of the two styles of margins for subduction dynamics remain poorly resolved. In this study, we used 2-D numerical simulations of subduction to investigate how ...
