Basin analysis in the Southern Tethyan margin: Facies sequences, stratal pattern and subsidence history highlight extension-to-inversion processes in the Cretaceous Panormide carbonate platform (NW Sicily)

摘要: Abstract In the Mediterranean, South-Tethys paleomargin experienced polyphased tectonic episodes and paleoenvironmental perturbations during Mesozoic time. The Cretaceous shallow-water carbonate successions of Panormide platform, outcropping in northern edge Palermo Mountains (NW Sicily), were studied by integrating facies stratal pattern with backstripping analysis to recognize tectonics vs. sedimentation interaction. features Requienid limestone, including geometric configuration, sequence, lithological changes significance top-unconformity, highlight that at end Lower platform was tectonically dismembered various rotating fault-blocks. variable trends subsidence curves testify different responses, both uplift downthrow, platform-blocks impacted extensional tectonics. Physical stratigraphic Rudistid limestone Upper previously faulted-blocks subjected vertical movements direction opposite displacement produced tectonics, indicating a positive inversion. Comparisons other sectors Southern Tethyan Adria paleomargins indicate these areas underwent same compressional stages occurring suggesting regional scale significance, time kinematics, for events.
