Abstract
After the collisional stage, the inner northern Apennines (i.e., southern Tuscany) have been affected by extensional tectonics, coeval with Late Miocene-Present magmatism. In the Boccheggiano-Montieri area hydrothermal mineralizations are located in the damage zones of the Pliocene normal faults and along the sub-horizontal detachment surfaces of the Oligocene thrusts and Miocene normal faults. On the basis of structural and fluid inclusions analyses, we propose a fluid-flow model with the older and youngest cataclasites hydrologically connected and commonly pervaded by the same geothermal fluids.File in questo prodotto:
