Sea Surface Temperature and Salinity Changes in the Easternmost Mediterranean During the Pre‐Evaporitic Messinian Controlled by the Restriction at Gibraltar

Paleoceanography and Paleoclimatology, Volume 41, Issue 1, January 2026.
Abstract During the latest Miocene, the Mediterranean Basin was affected by extreme paleoceanographic and paleoenvironmental changes culminating with evaporite (gypsum and halite) formation during the Messinian Salinity Crisis (MSC: 5.97–5.33 Ma).

Calcareous nannoplankton from Callovian deposits of Kanev's dislocation region

, 2016
Досліджено вапняковий нанопланктон з келовейських відкладів різних розрізів Канівщини. Наявність у ранньокеловейській товщі коколітів різного розміру свідчить про несталу солоність басейну седиментації.

A model for the concomitant early formation of dolomite and fibrous clays in coastal bay systems: Evidence from the Eocene (Paris Basin, France)

Sedimentology, Volume 72, Issue 6, Page 1860-1898, October 2025.
ABSTRACT Detailed analysis of Lutetian–Bartonian deposits in the Paris Basin (‘Marnes et Caillasses’ Formation) provides new evidence of concomitant magnesian fibrous clays (palygorskite and sepiolite) and early microcrystalline dolomite. Although relatively uncommon in sedimentary archives, palygorskite and sepiolite are found in a wide range of ...

Major Shifts in Equatorial Atlantic and Pacific Calcareous Nannofossil Assemblages Across the Early Eocene Climatic Optimum (EECO; ∼53–49 Ma)

Paleoceanography and Paleoclimatology, Volume 40, Issue 6, June 2025.
Abstract The early Eocene Climatic Optimum (EECO; ∼53–49 Ma) was the warmest sustained global warming episode of the Cenozoic, accompanied by major alterations in terrestrial and marine biota. Here we detail changes in low‐latitude calcareous nannofossil assemblages at two tropical sites in the equatorial Atlantic (ODP Site 1258) and Pacific (ODP Site ...

MIDDLE MIOCENE DROWNED RAMP IN THE VICINITY OF MARIJA BISTRICA (NORTHERN CROATIA)

Rudarsko-geološko-naftni Zbornik, 2018
Fossiliferous Middle Miocene deposits from the surroundings of Marija Bistrica (north-east of Zagreb) transgressively overly older pre-Cenozoic bedrocks. Fossils from shallow marine environments are in most cases preserved as bioclasts, while deep marine

Calcareous Nannoplankton Fossils and their Stratigraphic Meaning

Journal of Geography (Chigaku Zasshi), 1978
Modern calcareous nannoplanktons have an important role in marine food chain as a primary producelr. Fossils nannoplankton played an important part of the Mesozoic and Cenozoic biological world, and are now accepted as a very useful and accurate index fossil from the Jurassic to Recent Period.In this article recent advance of nannoplankton ...
