AB Cherts occurring in oolitic limestones of the Dogger in the Internal Subbetic, are studied for the first time. Two genetic hypothesis are considered from the interpretation of the stratigraphic, petrological and geochemical data. The one first considers that the silicification took place in relation with continental groundwater, in the Middle to Late Jurassic transition, forming silcretes. The second one, shows the silicification as generated from marine waters in diagenetic environments at relatively higher temperatures, during Late Jurassic-Early Cretaceous times
