Quantitative Analysis and Paleoasociations of the Aptian Urgonian Complex in the Ouenza Area (NE Algeria)

The Aptian deposits of the easternmost part of the saharian Atlas, are represented by shallow carbonate platform limestones and the outer platform marly sediments. The application of statistical methods to the analysis of the microfacies by the factorial analysis of correspondances and the classification by the dynamic cluster method allows us to visualize the ecosequential evolution and the various biological associations.
