“…An intraMessinian "phase" is also recorded in the Southern Apennines (Ortolani, 1979) as well as in Calabria (Moussat, 1983). In Sicily, an unconformity splits the Messinian interval into two cycles (Decima and Wezel, 1973).…”

“…According to Roda (1964) the three units of Messinian age overlying the "Tripoli" are, respectively, 150 meters thick (lower evaporitic formation), up to 450 meters thick (detrital-saline formation), and up to 400 meters thick (upper evaporitic formation). c) land exposures, mines and wells in Sicily, where the thickness is up to 1500 meters (Decima and Wezel, 1973).…”

Sedimentation rates calculated for Mediterranean deep-sea sediments predating the onset of the salinity crisis range from 2.5 to 9 cm/1000 years. Accumulation rates for the Messinian age evaporites are highly variable and likely to be excessive by more than one order of magnitude (i.e., more than 1 km/m.y.). Sedimentation rates calculated for the Pliocene/Pleistocene range from more than 30 cm/1000 years (Pleistocene of the Nile Cone area) to less than 0.1 cm/1000 years (early Pliocene of the Antalya Basin), the average value (including minor hiatuses) being 5.9 cm/1000 years.The anomalously low rate of sediment supply in Pliocene times to locations which at the present day are basinal settings is interpreted as a consequence of a rapid eustatic sealevel rise, which accompanied the marine flooding of a depressed water body at the close of the late Miocene salinity crisis. The subsequent increase in the Quaternary to values equivalent to those attained prior to the salinity crisis is an indication that the modern surfaces of deposition are now in equilibrium.Tectonically controlled facies changes are consistently accompanied by detectable changes in rates of sediment accumulation, as recorded in the Pleistocene of the Levantine and Antalya basins.

“…The onset of the lower evaporite deposition Decima and Wezel, 1973) occurred between 5.8 and 5.5 Ma (Gersonde and Schrader, 1984;Muller and Hsü, 1987 Hodell et al, 1989). In the 600,000-900,000-yr interval prior to evaporite deposition (between 6.4 and 5.8-5.5 Ma), pronounced changes occurred within the Mediterranean (McKenzie et al, 1979).…”

Carbonate stratigraphy and stable isotopic ratios of benthic and planktonic foraminifers were used to study paleoceanographic changes that occurred during the late Miocene to earliest Pliocene in the subantarctic South Atlantic, between 9.8 and 4.5 Ma in ODP Hole 704B on the Meteor Rise (47°S, 7°E; 2532 m water depth).During the late Miocene, between 9.8 and 6.4 Ma, carbonate content was high with little variability (generally 84.5% ± 10%), with sustained productivity dominated by foraminifers and calcareous nannoplankton in surface waters north of the Subantarctic Front. Decreased carbonate (40%), along with first significant occurrence of biogenic opal, occurred between 8.45 and 8.2 Ma. The first signals of increased cooling occurred between 8.8 and 8.0 Ma.The interval from 6.3 to 4.5 Ma represents low carbonate values with high variability (61.7% ± 17%), suggesting markedly fluctuating conditions in the production and/or dissolution of carbonate. The onset of this interval in Hole 704B is marked by a decrease in carbonate values and a well-defined 0.85°/oo decrease in δ 13
