Cartoon to describe our interpretation of the crust-mantle detachement (red) and cover décollement (blue) interactions in the mantle exhumed domain. This figure depicts our interpretation of the genesis of the Urdach breccia by exhumation of tectonic breccia followed by gravity-driven reworking on the seafloor. Note the strong boudinage and tectonic attenuation of the pre-rift cover and the disruption of the Triassic layer in relation with high-displacement along the cover décollement.
