RT Journal Article T1 Secuencia diagenètica temprana de la plataforma carbonatada con paleocarst de Arenillas (Albiense, Oriñón, Cantabria) A1 Rosales, Idoia A1 García Mondéjar, Joaquín AB 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 PB Sociedad Geológica de España YR 1992 FD 1992 LK http://hdl.handle.net/10272/14145 UL http://hdl.handle.net/10272/14145 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 2 jun 2026
