    Preliminary Description: 

    There are gradual alternations of dense and less dense sediment. There are millimetric to pluricentimetric clasts in the whole core and some dense inclined laminations. The x-ray, between 70 and 80 cm, is completely black. The sediment is well recorded only in the central section of the whole core.
