Short summary
The local topographic slope of an accretionary prism is often used to determine the effective friction on subduction megathrust. We investigate how the brittle–ductile and the smectite–illite transitions affect the topographic slope of an accretionary prism and its internal deformation to provide clues to determine the origin of observed low topographic slopes in subduction zones. We finally discuss their implications in terms of the forearc basin and forearc high genesis and nature.
