Carbonate platforms as recorders of high‐amplitude eustatic sea‐level fluctuations: the late Albian appenninica‐event
Abstract The mid‐Cretaceous was a time in which rapid vertical carbonate accumulation alternated with intervals of world‐wide crisis on carbonate platforms. Next to the well‐known mid‐Valanginian, mid‐Aptian and Cenomanian/Turonian event, the late Albian Rotalipora appennirjica‐7.one is a period of...
