Abstract
Colour Alteration Index (CAI) of conodonts from the Middle and Late Visean sediments in the central domain of the Azrou-Khénifra Basin showed values between 2.5 and 4.5 corresponding to paleotemperatures between 90 °C and 250 °C. The present day thermal maturity may be explained by sedimentary burial, emplacement of gravity-driven nappes and thrust westward during the Visean stage of the Variscan orogeny. A gradual increase in CAI values eastward is compatible with a gradual transition from diagenesis in the west to low-grade metamorphism in the east.
