    Preliminary Description: 

    The sediment is dense and grain supported with some centimetric laminations up to 27 cm, followed by a less dense sediment with millimetric laminations and few clasts (from millimetric to pluricentimetric in length). The sediment becomes denser and grain supported between 114 and 119 cm while between 119 and 170 cm is less dense with clasts. There are centimetric laminations delimited by a net contact between 170 and 176 cm. Low density sediment with millimetric laminations returns between 176 and 185 cm. The sediment is grain supported from 185 cm to the bottom.
