    Preliminary Description: 

    The x-ray is characterized by levels without sediment. Low density sediment with clasts which length is millimetric to pluricentimetric. It gradually changes from low density sediment to laminated sediment (laminations are mainly millimetric and few are centimetric) with millimetric and centimetric clasts. There is again less dense sediment (millimetric to centimetric in lenght). The change of density is characterized by net contact from 435 up to 455 cm.
