Los materiales del tránsito Triásico-Jurásico en la región de Villaviciosa (Asturias, España). Caracterización palinológica

A lithostratigraphic and palynologic study of the sediments corresponding to the Triassic-Jurassic transition at the Bárzana section, located in the Villaviciosa region (Asturias), has been carried out. Four lithostratigraphic units have been distinguished: A) Black and maroon lutites with evaporite...
