Resumen: El modelo sedimentológico convencional relaciona la acumulación de rocas sedimentarias de grano fino (<62,5 μm), ricas en materia orgánica, únicamente con procesos de decantación hemipelágica en ambientes de baja energía. En esta contribución se analiz

Abstract: The conventional sedimentological model suggests that the accumulation of organic-rich fine-grained sedimentary rocks (<62.5 μm) is uniquely associated with fallout processes in low energy depositional environments. This contribution analyzes organic-rich mud
