TL;DR: In this article, a deep-sea core over 16 m long from the crestal area of the Mediterranean Ridge has been investigated with different techniques, including quantitative micropaleontology, stable isotopes (measured on the epipelag species Globigerinoides ruber and on the mesopelagic species Globorotalia inflata), and clay mineralogy.

TL;DR: Paleoecology and paleohydrology of the Ramlat as-Sab'atayn (Southern Arabia) are reconstructed from a comparative study including sedimentology, mineralogy, stable isotope ratios of carbonates, and palynology of lacustrine sediments recovered from the al-Hawa depression as mentioned in this paper.

TL;DR: In this paper, the Eocene-Oligocene climate transition (33.8-32.5 Ma) was analyzed in Ocean Drilling Program Site 689, Maud Rise, Antarctica.

TL;DR: In this paper, high resolution interdisciplinary analyses of the clay and coarse (>40 μm) fractions of ODP Leg 113 Site 690 Eocene-Oligocene sediments on the flank of the Maud Rise, provide information on paleoproductivity, water masses, paleoclimate and erosion in the Antarctic range as well as on the cyclicity of these processes.

TL;DR: Rassemblees avec des resultats deja disponibles dans le bassin mediterraneen (Legs 13 et 42 A DSDP) and sur ses bordures (Algerie, Sicile, Espagne), de nouvelles donnees obtenues en Italie du Nord, Provence et Espagne du Sud conduisent a faire le point sur la sedimentation argileuse au Tortonien superieur, au Messinien and au Pliocene inferieur.
