Orbitally-forced palaeoenvironmental and palaeoclimate changes in the late post-evaporitic Messinian of the central Mediterranean Basin

""Paleoenvironmental and paleoclimate. changes that occurred during the late postevapo. ritic stage of the Mediterranean Basin. in the Messinian foreland domain of the. Adriatic region offer a new perspective on. the relationship between orbital forcing and. climate response. The magnetic susceptibility. record of the Fonte dei Pulcini A section (Maiella. Mountains, Italy) allows us to orbitally. tune the record between 5.394 and 5.336 Ma. and to temporally constrain the paleoenvi. ronmental and paleoclimate changes. evidenced by quantitative paleontological. (palynomorphs, ostracods, and calcareous. nannofossils), stable isotope (δ18O and. δ13C), and X-ray diffraction (XRD) analyses.. The base of the Fonte dei Pulcini A section is. characterized by Paratethyan ostracods and. dinocysts, which point to the late Messinian. Lago-Mare biofacies (Loxocorniculina. djafarovi zone) of the Mediterranean Messinian. stratigraphy. From paleontological. and geochemical (δ18O) analyses, there is no. evidence of a marine incursion in the Fonte. dei Pulcini A section. The major changes in. terms of paleodepth, paleosalinity, evaporation. versus precipitation, aridity versus humidity,. and reworking processes occurred in. the upper part of the Fonte dei Pulcini A section,. during the last Messinian insolation. cycle (i-cycle 511\\\/512), which is characterized. by high-amplitude oscillations. In contrast,. the lower part of the Fonte dei Pulcini A section,. which was deposited during relatively. low-amplitude insolation cycles, is characterized. by more stable environmental conditions.. Comparing summer insolation with the. paleoenvironmental changes at the Fonte dei. Pulcini A section, we identify delays of several. thousands of years between orbital forcing. and climate response.""
