The study of the evolution of clay minerals in the sedimentary record allows a simple estimation of the temperatures reached by deep clastic basins, constituting a low-cost and powerful tool to understand their mechanical and thermal properties, fundamental in tectonic and geodynamic reconstructions. In turn, the isotopic characterization of these minerals allows assigning ages to the identified growth episodes. Fractions of different grain size (
