The Maccarone sedimentary sequence (Upper Miocene to Lower Pliocene), located in the Marchean Outer Basin (Macerata, Central-Eastern Italy), was examined.

Abstract
The Maccarone sedimentary sequence (Upper Miocene to Lower Pliocene), located in the Marchean Outer Basin (Macerata, Central-Eastern Italy), was examined. The depositional sequence consists of a Messinian succession (about 210 m in thickness) including marly clays, clayey marls and evaporitic limestones. The mineralogy and geochemistry were studied. The results reveal a sequence of important changes caused by differences in the evaporation-precipitation balance and in the depth of the Maccarone Basin, associated with variations in marine and continental contributions from Upper Miocene to Lower Pliocene.
