Dolomitization is associated to a first order sequence boundary, evolved from upper to lower and affected very shallow marine sediments. A diagenetic sequence from evaporative, to marine and meteoric mixing ambients, to a later freshwater generalized input can be inferred from both the study of micro textures and cathodoluminescence observationsspaAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/Upper CretaceousBasque-Cantabrian BasinSedimentary rupturesCarbonate diagenesisDolomitizationCalcitizationjournal articleopen access
