Los pares caliza-marga de la Isla de Castro (Coniaciense final-Santoniense inferior, Cuenca Vasco-Cantábrica): variaciones isotópicas (á!80 y á13C) y mineralógicas

Analyses carried out on bedded limestone-marl couplets from Castro Island section (latest Coniacian-lower Santonian, Basque-Cantabrian Basin) show clear isotopic (a'780 and al3C) and mineralógica! differences between limestones and marls. Analytical results point out that the sediments suff...
