    Preliminary Description: 

    There is an alternation between less dense and dense sediment with more clasts (millimetric to centimetrics). There are some weak millimetric laminations. This portion is followed by low density sediment that is characterized by an alternation of levels rich in clasts and levels with rare clasts, separated by irregular contacts. The sediment is denser and coarser in the last 60 cm of the core. There are some fractures from 100 cm up to the bottom. Between 238 and 240 cm there is a level composed of clasts.
