Figure 3. Three-dimensional schematic diagram of the geodynamic model proposed in this study based on tomographic studies (Calvert et al. 2000; Gutscher et al., 2002; Faccenna et al., 2004 ; Spakman and Wortel, 2004). Base of the overlying lithosphere is schematically represented as a plane. C.L—continental lithospheric mantle (green domain); O.L—oceanic lithosphere (white domain). The shaded arrow represents the sinking of detached western Mediterranean slab. Black arrow is the pull of the oceanic part of the slab at depth. Red hachured area and red arrow are modeled traction patch (Fig. 2C) simulating the remaining coupling interaction between the slab and the overlying lithosphere. Blue circles are 60–120 km depth seismicity (see Fig. 1).
