Cesare Emiliani was born as a son to Luigi and Maria (Manfredidi) Emiliani on December 8, 1922 in Bologna, Italy. He studied geology at the University of Bologna, specializing in micropaleontology. He received the D.Sc. from the University of Bologna in 1945. His earliest publications concerned philately, an interest that continued throughout his life. After graduation he worked as a micropaleo...

Optical microscopy analyses using thin sections is one of the most standard techniques in geology. It permits identification rock-forming minerals and it essential for micropaleontology since observation transmitted light only way to observe individual, or colonies of, microfossils their mineralogical textural context. Thin are also used other such as Raman spectroscopy. In framework exploratio...

After the 2004 Indian Ocean (IOT) and 2011 Tohoku-oki tsunamis, new research in tsunami-related fields was strongly stimulated worldwide also Mediterranean. This growth yields substantial advancements tsunami knowledge. Among these is “Paleotsunami” that has marked particular progress on reconstruction of history a region. As an integration historical documentation available Mediterranean Gulf ...

While Pleistocene glacial-interglacial cycles are commonly associated with strong waxing and waning of Northern Hemisphere ice sheets, the response Antarctic sheet regional changes in oceanographic environmental conditions to climate dynamics remain poorly constrained. We present a reconstruction sea-ice cover, sea surface temperature primary productivity off Ross Sea margin (Adare Basin at slo...

We present a detailed geologic study of the Thebes Formation at Gebel Gurnah in its locus typicus on the West Bank (opposite Luxor) of the Nile River in the Upper Nile Valley, Egypt. This is the first detailed measurement and lithologic description of the ~340 m thick (predominantly) carbonate section. The Thebes Formation is divided into thirteen major lithic units (A to M). We interpret data ...

The recurrence of Braarudosphaera chalks in the lower Oligocene sequences of the subtropical South Atlantic has been a long-standing conundrum, with many hypotheses having been advanced to explain the genesis of these exotic nannofossil assemblages. Here, we evaluate different paleoceanographic models within the context of stable isotope (N18O, N13C) data measured from bulk-sediment samples and...
