Transición dúctil-frágil en la corteza de la zona central de la Península Ibérica

Brittle-ductile transition is estimated on the basis of pore-pressure dependent frictional failure in the brittle regime, and power-Iaw steady-state creep in the ductile regime. Structure and lithological composition of the Centrallberian Peninsula Crust combined with geotherm are used to generate r...
