Evolución megasecuencial de los materiales oligo-miocenos del sector septentrional de la Cuenca del Ebro (provincia de Huesca)

Abstract

The outcropping continental detrital formations in the northern margin of the Ebro Basin between the Sierras Exteriores Aragonesas and the Sierras Marginales Catalanas have been analyzed. These materials form part of the classic Peraltilla and Sarinena Formations. This study demonstrates the ambiguity which exists in delimiting of both formations. The study of the megasequential evolution of the materials may provide new criteria to precise the limit between them
