This unit is bounded at its base and top by the intraUpper-Bajocian and intra-Upper-Bathonian sedimentary breaks, respectively. Field data (paleofaults, lateral wedging, neptunian dykes...) point to significant tectonic influence. Therefore, the tectonic factor could have been more important than the eustatic changesspaAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/Tectonic controlGenetic unitIntra-upper Bathonian sedimentary breakjournal articleopen access
