Benvenuti nell'Anagrafe della Ricerca d'Ateneo
La valutazione delle attività di ricerca che si svolgono nelle università ha assunto un'importanza rilevante sia per l'intero sistema universitario sia all'interno di ogni singolo ateneo. Roma Tre si è quindi dotata di idonei strumenti informativi in grado di supportare al meglio le azioni di monitoraggio e di valutazione delle attività di ricerca svolte nei propri dipartimentied ha realizzato una Anagrafe della Ricerca di Ateneo.
EnglishAt the end of the Messinian salinity crisis, changes in the palaeoceanography and palaeoclimate induced a transition from hypersaline to hyposaline conditions in the Mediterranean water body. Detailed investigation of natural radioactivity and microfacies analyses of two early post-evaporitic Messinian sections show that the transition occurred in poorly oxygenated and well-stratified water masses. These transitional deposits, which mainly consist of marls and CaCO3-rich horizons, are generally well laminated and totally barren in benthic and planktonic fauna. The presence of barite, small (5–8 lm) authigenic framboidal pyrite, and high values of U indicate persistent anoxic conditions during the early postevaporitic Messinian stage in the Adriatic sub-basin of the Mediterranean Sea. The presence of post-evaporitic welllaminated barren deposits from both Mediterranean borderland sections and ODP sites suggests that these anoxic conditions extended to other sub-basins of the Mediterranean region.

| Abstract: | At the end of the Messinian salinity crisis, changes in the palaeoceanography and palaeoclimate induced a transition from hypersaline to hyposaline conditions in the Mediterranean water body. Detailed investigation of natural radioactivity and microfacies analyses of two early post-evaporitic Messinian sections show that the transition occurred in poorly oxygenated and well-stratified water masses. These transitional deposits, which mainly consist of marls and CaCO3-rich horizons, are generally well laminated and totally barren in benthic and planktonic fauna. The presence of barite, small (5–8 lm) authigenic framboidal pyrite, and high values of U indicate persistent anoxic conditions during the early postevaporitic Messinian stage in the Adriatic sub-basin of the Mediterranean Sea. The presence of post-evaporitic welllaminated barren deposits from both Mediterranean borderland sections and ODP sites suggests that these anoxic conditions extended to other sub-basins of the Mediterranean region. |
