The post-Variscan uplift of the western Anti-Atlas Precambrian core is studied by zircon fission track (ZFT) analysis of ten samples of granites and schists from the Kerdous and Ifni inliers. All samples yield Carboniferous ZFT ages ranging from 358±31Ma to 319±32Ma, with nine dates younger than 338±35Ma. The weighted mean age calculated for these nine samples is 328±30Ma. These results compare with...
