Facies de canal, margen de canal e intercanal en turbiditas carbonatadas. Berriasense inferior: Ventana de Cabra del Santo Cristo. Cordilleras Béticas.

Abstract

The Lower Berriasian turbidite carbonate sequence into the Cabra Sto. Cristo tectonic window provide an outstanding reference of palaeoenvironmental significance. The facies associations can be fitted into a model of channeled submarine deposition. Three main facies associations occur: 1) channel-filí deposits: conglomerate facies overlain by finer grained and thinner bedded facies; 2) channelmargin facies: Thin-bedded turbidites with virtually no mudstone interbeds; 3) interchannel facies: Bundíes of interbedded mudstone/ calcarenite included into mudstone units with broadiy channelized calcarenites. These beds are organized into repetitive positive cycles; the complete sequence forms a recessional suite grading from channelized deposits to basin plain turbidites. Attempts of -stratigraphic correlation are shown.
