Modelización de la migración de fluidos y del transporte de calor en cuencas sedimentarías compresivas: aplicación a la cuenca de Ainsa

Resumen

We present a method of modeling the hydraulic and thermal evolution of sedimentary basins that undergo compressive deformation. A finite-element mesh generatoris used , that is capable of creating bandwidth optimized meshs taking into account geometrical deformations caused by sediment consolidation, lateral movements of thrust sheets and erosion al events. A finite-elements modelis used to solve the equations of fluid flow, sediment consolidation as well as solute- and heat transport. We apply the model of the Southern Pyrenean foreland basin of Ainsa in order to constrain fluid flow evolution during the emplacement of thrust sheets. Furthermore, we compare the data obtained by petrological and geochemical studies in the Ainsa bain host rocks and veins to corroborate the application of this method
