    Preliminary Description: 

    Homogeneous dense sediment that contains a few subcentimetric clasts up to 20 cm (bottom of section III). The sediment is rich in clasts from 20 up to 32 cm. There is a net contact at 32 cm. The sediment’s density gradually decreases with some pluricentimetric denser levels with few clasts up to the bottom of the core.
