Abstract
During the Upper Jurassic (Kimmeridgian/Tithonian) the distribution of organic matter content was not random but characterized by elementary cycles nested within each other. Sites of maximum enrichment are loca ted at precise stratigraphic levels which are the same at different po ints surrounding the NW European margin. These paroxysms, geographical ly distributed along ''organic belts'', are more or less expressed acc ording to the combination of physiographic, eustatic and climatic para meters. They are studied here on subcrops and outcrops from Yorkshire, Dorset and Boulonnais.
