    Preliminary Description: 

    The sediment is homogeneous and it contains a few subcentimetric clasts up to 50 cm. This section is separated from the underlying one by an irregular contact. The sediment becomes rich in clasts (millimetric to pluricentimetric in length). There are laminations due to reduced amounts of sediment.
