Abstract The Messinian Salinity Crisis (MSC; 5.97–5.33 Ma) is an enigmatic episode of paleoceanographic change, when kilometer‐thick evaporite units were deposited in the Mediterranean basin. Here we use geochemical (biomarker and isotope) data to reconstruct sea surface temperature, salinity, productivity‐preservation changes basin just before MSC. proxy indicate that Sea was significantly saltier colder between 6.415 6.151 Ma, than 5.971 Ma. decrease at Ma seems be a relatively fast event...
Abstract This integrated study (field observations, micropalaeontology, magnetostratigraphy, geochemistry, borehole data and seismic profiles) of the Messinian–Zanclean deposits on Zakynthos Island (Ionian Sea) focuses sedimentary succession recording pre‐evaporitic phase Messinian salinity crisis ( MSC ) through re‐establishment marine conditions in a transitional area between eastern western Mediterranean. Two intervals are distinguished palaeoenvironmental reconstruction Kalamaki: (a)...
Abstract The Early Toarcian (Early Jurassic, c . 183 Ma) was characterized by an Oceanic Anoxic Event (T-OAE), primarily identified the presence of globally distributed approximately coeval black organic-rich shales. This event corresponded with relatively high marine temperatures, mass extinction, and both positive negative carbon-isotope excursions. Because most studies T-OAE have taken place in northern European Tethyan palaeogeographic domains, there is considerable controversy as to...
A global perturbation in the carbon cycle has been recorded Early Toarcian (~ 183 Ma) and is marked by enhanced organic-carbon burial mass extinction. It also associated with high palaeotemperatures, both positive negative excursions carbon-isotope ratios, development of anoxic to euxinic conditions marine environments: together these phenomena have designated as constituting an Oceanic Anoxic Event. Here we provide a high-resolution, multiproxy biostratigraphic chemostratigraphic study from...
