Timing of rodingitization at the Ronda peridotites (Betic Cordilleras, Spain)
This work reports the timing of the rodingitization process of granitic dykes intrusive into the Ronda Peridotites. Representative fission-track ages on zircon and apatite from rodingitized dykes, in combination with cooling rates suggested for the Alpujarride Complex (Monié et al., 7 994; Sánchez-R...

| Resumo: | This work reports the timing of the rodingitization process of granitic dykes intrusive into the Ronda Peridotites. Representative fission-track ages on zircon and apatite from rodingitized dykes, in combination with cooling rates suggested for the Alpujarride Complex (Monié et al., 7 994; Sánchez-Rodrfguez, 1 998; Sosson et al., 1998) point to a minimum age of 16.8 ± 1.8 Ma for the rodingitization process. By extrapolating to the timing of formation of the highest stability limit of the serpentine minerals (500°C) we propose that the serpentinization of Ronda peridotites was a continuous process lasting at least for 2.2 Ma, from 19.1 to 16.9 Ma. |
