- •
The sedimentary record is divided into three synthems: Messinian I (pre-evaporitic), Messinian II (syn-evaporitic), and Pliocene (post-evaporitic).
- •
Marls associated with gypsum beds (syn-evaporitic phase) record dwarf planktonic foraminifera.
- •
The syn-evaporitic phase (chron 3Cr) records major changes in water salinity in a stressed marine environment.
- •
Two erosional surfaces correspond to the intra- and end-Messinian unconformities.
- •
The end-Messinian unconformity is represented by an incised paleovalley.
