We correlate carbonate shelf in wedge-top basin with seep episodes in the foredeep. Seep-carbonates are useful stratigraphic markers and climate-tectonic sensitive proxy. Evolutionary phases of Miocene temperate-type carbonates are outlined. Synsedimentary tectonics control the onset and crisis of carbonate sedimentation. Terrigenous discharge and Mi3b climate cooling favored the drowning of the shelf.
