Slow active faults along the extensional northeastern margin of the Iberian Peninsula

6 pages, 1 figure, 1 tableThe active faults located in the northeastern margin of the Iberian Peninsula are related to the extension and opening of the Valencia Trough basin. In this area, the extension began in the Neogene and two tectonic phases have been proposed (Roca, 1992, 1994, 2001, 2004; Roca and Guimerà, 1992; Roca, Roca et al., 1999; Cabrera et al., 2004): a) the rifting phase, that lasted from late Oligocene to middle Miocene, during which a rift system, with a total extension of 7.1 km, developed; and b) the thermal subsidence phase, that has been characterized by moderate tectonic activity, mainly localized at the borders of the basin, and a total extension of 4.1 km since the middle Miocene and to the present.
