Resumen

The five shallow water carbonate depositlonal sequences oftheAlbian Arenillas platform in Oriñón, N Spain, are bounded by palaeokarst surfaces. Detailed petrographic and cathodoluminescence studies have revealed that the early diagenesis was similar in each cycle. This early diagenetic sequence shows 5 consecutive stages: 1) Stagnant marine phreatic zone, 2) Active marine phreatic zone, 3) Mixing marine and meteoric phreatic zone, 4) Meteoric phreatic zone and 5) Vadose and marine-vadose zone
