Geology ; 46 3: Direct dating of brittle structures is challenging, especially absolute dating of diagenesis followed by a series of superimposed brittle deformation events. We report 22 calcite U-Pb ages from tectonites and carbonate host rocks that date 3 diagenetic and 6 brittle deformation events.
Results show that U-Pb dating of calcite fibers from these structures is compatible with overprinting relationships. Eight ages from strike-slip faults U/pb-dating of calcite slickenfibres thrusts resulting from northeast-southwest shortening range from The youngest ages are from minor overprinting fibers ranging in age between 7. Our results show that U-Pb dating of calcite fibers can be successfully used to constrain a complicated succession of brittle deformation structures that encompasses two orogenies and an intervening extension period.
