Abstract

The Montagut fault system stands as part of the Sant Corneli and Boixols anticline, located in the frontal part of the Boixols thrust belt of the southern Pyrenees, as developed during the Alpine compression. Structural in-field data, as associated with petrographic and cathodoluminescence study, has yielded recognition of three different generations of calcite cement relating to different fluid-flow deformation stages. During the layer-parallel shortening, as related to the early folding stage, fluids proved to circulate through strike-slip and normal faults precipitating in the form of cement Cc1 and CC2. During the fold growth stage, calcite cement three was precipitated filling micro-vein coeval to the generation of stylolite, and could likely well represent the active deformation episode.
