    Preliminary Description: 

    The whole core is characterized by a dense sediment with a lot of clasts (subcentimetric but some ones is pluricentimetric in lenght). Between 60 and 140 cm there are some millimetric and centimetric low density laminations. Irregular contacts separate less from more dense levels of sediment.
