• Resumen

  • A tripartite sequence with a lower dense flow deposit division (I), an intermediate traction flow deposit division (II) and an upper hemipelagic deposit division (III) is proposed here according to careful observations in field and measurements of each division thickness in the sedimentary sequence. And this sequence can be interpreted as interactions of internal waves (include internal tides) and turbidity currents.
