El paleokarst de Nazaré (Cretácico Superior de la Cuenca Lusitana, Portugal)

Abstract

In the Nazare region, (west Portuguese coast) there is an exceptionally well exposed paleokarst associated with the Upper Cenomanian carbonate succession and the overlying siliciclastics series of probable Turonian-Campanian age. The progradational trend of this succession as well as its depositional geometries show that sinsedimentary tectonic activity influenced the different diagenetic and paleokarstic features
