Paleoceanographic evolution of western Tethyan (Ionian Ocean) Lagonegro Basin
- •
Subbasins with different sediment patterns developed due to half-graben formation
- •
Time-transgressive carbonate to biosilica transition caused by basin subsidence

Marine productivity was low and deep-water redox conditions were mainly oxic.
