Abstract

Subaerial erosion and continental sedimentation interbedded with shallow-water carbonates are unequivocalstratigraphic records to evaluate paleoenvironmental and paleoclimate evolution of emergedlandmass.Stratigraphic analysis of the Cretaceous Monte Gallo section of the Mesozoic Panormide carbonateplatform, in the northern side of the Palermo Mountains (NW Sicily) records a peculiar continentalderivedclays that interrupted the shallow-water carbonate sedimentation. These clays rest, withlenticular geometries, above the tectonically-enhanced subaerial erosional unconformity of theBarremian-Lower Aptian Requienid limestones and are covered by the Upper Cretaceous Rudistidlimestone.Sedimentological investigation combined with mineralogical and petrographic results reveal theoccurrence of alkaline to saline lake clays deposition in pond-filling depositional environment recordingstressed conditions (evaporation) especially in its final living phase. They were formed when a halfgraben/tilted-block tectonics produced footwall uplift of the Gallo faulted-blocks carbonate platform.Paleoclimate evaluations of the continental-derived clays highlighted that a period of warm-humidconditions, which favoured their formation, interrupted the uniform warm climate conditions highlightinga greenhouse climate phase.
