Astronomical tuning of the Tortonian 87Sr/ 86Sr curvein the Mediterranean basin

2002
This work presents a detailed 87Sr / 86Sr isotope curve for the interval 7.5–9.7 Ma obtained by a high-resolution analysis (sampling spacing of about 40 kyr) of an astronomically calibrated land-based sedimentary sequence exposed in the central Mediterranean area (Gibliscemi section, southern Sicily). The main aim is to verify a synchronous response of

Oyster distribution in the upper tortonian of the Almanzora Corridor (Almeria, S.E. Spain)

Geobios, 1991
Abstract During the upper Tortonian a variety of different sedimentary environments developed in the Almanzora Corridor, a narrow, elongate E-W, Neogene basin in SE Spain. This environmental diversity was caused by the presence of fan deltas and deltas together with coral reefs in some areas of the marine basin.

The genus Cytherella Jones, 1849 (Ostracoda) in the Italian Tortonian – Recent:

1996
Italian species of the genus Cytherella Jones, 1849 are studied from the Tortonian to Recent interval. Thirteen species are treated, 12 of which are illustrated. The lectotype and a paralectotype of Cythere ? serratula Brady, 1880 are also illustrated for comparison. Three species, Cytherella cercinata, C. gibba and C. vulgatella are described as new.

Serravallian-Tortonian buried stratigraphy of Crotone basin: sedimentary and compositional evolution

2022
The starting phase of the Crotone Basin infill is recorded by a siliciclastic Serravallian–Tortonian cycle, reliable both on outcrop and in the subsurface. In this study, a total of 16 well logs, located both onshore and offshore, were analysed to evaluate the stratigraphical and sedimentological variations along transects of 60 km (N-S) and 27 km (W-E)

Evolution of the drainage system in the SE Betic Cordillera since the Tortonian

2013
The emersion of Betic Cordilleras (Sierra Nevada, Sierra de Gador) and associated marine neogene basins is the result of recent tectonic processes. This emersion was followed by the installation of drainage systems (rio Andarax, rio Adra) where detrital products were trapped at their outlets with morphosedimentary shapes as deltas or alluvial fans ...

The paleoenvironments of late Tortonian phosphatic hardgrounds (Latium–Abruzzi Platform, Italy)

Miocene hardgrounds of the circum-Mediterranean region are widely interpreted as records of nutrient-rich upwelling, commonly associated with phosphatization along platform margins. On the Latium–Abruzzi Platform, the Sirente Mt and Tornimparte successions document two distinct phosphogenic settings: in situ authigenic hardgrounds and reworked ...
