Resumen de Calderas volcánicas pasivas: un ejemplo en el Estefaniense del Pirineo Catalán

Joan Martí Molist, J. Mitjavila

• A model of volcanic cauldron (pasive volcanic cauldrons) is proposed for sorne LateHercynian basins of the Catalan Pyrenees. This volcanic structure is defined as a sedimentary basin in which the subsidence processes are accelerated by the vo!canic activity triggered by the same tectonic processes which are responsible for the basin formation.
