The present study evidenced the effects of early post-rift deformation stages in an evaporite unit and their linkage to basin scale events. It has been established the parental fluids of the fracture infillings of the Vilobí Gypsum Unit and their evolution during the different precipitation events. Geochemical data reveals chemical recycling processes linked to fluid flow along the fractures dissolving the closest sulphates. Thus, each successive infilling event resulted from recycling of the preexisting gypsum.
