Abstract

Two major sedimentary cycles in the Lower Cretaceous (Berriasian-Barremian) sequence of the Organyà Basin, south-central Pyrenees, Spain, are identified on the basis of the ranges of some foraminiferal species and an analysis of the sediments. The first is Berriasian-Valanginian in age and characterized by a sequence which represents shallowing upwards from basin and/or outer platform to inner restricted platform environments. The second is of Barremian age and composed of two parts. The older section is characterized by marine deposits of high energy, the younger by low energy deposits from protected or lagoonal environments of varying salinity. © 1990 Academic Press Ltd.
