ANCIENT SLOPE DEPOSITS (6) LANDSLIDE DEPOSITS (5)
Poorly-stratified grey clay and well-stratified with decimetric strata leaden fetid silty-clay alternation. Locally
cross-lamination is present. Crystal gypsum intercalations (from decimetric to multiple metric bodies) are present between clays layers; crystals are contained in a havana gessarenite matrix. There are also millimetric levels of white gypsum. Outcropping thickness is up to >200 m.
CLAYS (7)
Centimetric and decimetric stratified clasts cemented and locally poorly cemented. Thickness is 20-25 m.
Silty-clayey deposits with crystal gypsum in a chaotic setting. Thickness varies up to >25 m.
Reworked material with clays, silts and gypsum blocks with chaotic setting, locally inside silty-clayey matrix. Thickness varies from <2 m up to <5 m.
Heterometric gravels with silt and sand layers. Thickness varies up to 10 m.
Clays, sillt and sand with centimetric calcareous clasts. Thickness varies up to 5 m.
Loose heterometric clasts in a silty-sandy matrix. Thickness varies up to 10-15 m.
