Short summary
Clay minerals are witnesses of alteration conditions in continental environments. Lacking high-resolution data on clay minerals, this work highlights wet and semi-arid cycles at mid-latitude in the upper Sinemurian. The higher proportion of kaolinite in the upper part of the obtusum zone and in the oxynotum zone indicates an increase in hydrolysis conditions in a warmer period confirmed by carbon isotopes.
