Basin‐scale correlation of Messinian salinity crisis (MSC) deposits across the Apennine–Albanide foreland basin system integrating outcrop and subsurface data. ABSTRACT We reconstructed the geological evolution of the Albanides during the Messinian salinity crisis (MSC), based on the integration of outcrop and subsurface data from both onshore (peri ...

The Badenian/Sarmatian boundary in the Central Paratethyan basins is characterised by a change from open marine conditions during the late Badenian to the assumed brackish conditions during the early Sarmatian. The foraminiferal and palynological results

Assessment of the Cape Blanc (northwest Africa) upwelling ecosystem response to recent climate change, using wavelet analyses on dinoflagellate cyst export [PDF]
Accelerated rates of change in recent climate have urged comprehensive investigations of its impact on marine ecosystems, notably those with high bio-, socio-, and economic importance, such as the upwelling ecosystem off Cape Blanc, Northwest Africa ...

Abstract Constraining how faunal communities vary over time and space in response to environmental change has long been a major goal of paleoecologists. Among fossilized organisms, few yield a better and greater detailed record than foraminifera to understand past marine conditions.

Stepwise Cooling Events in the Western Arctic at 8.2 and 4.2 ka: Proxy Development and Application
Abstract Hydroxylated glycerol dialkyl glycerol tetraether (GDGT)‐based proxies have recently been proposed for reconstructing sea surface temperatures (SSTs) in polar oceans, but their reliability has not yet been sufficiently validated. We investigated the spatial distribution of hydroxylated GDGTs in surface sediments from the western Arctic Ocean ...

A 30 m long sedimentary succession at the bottom of the Belize Blue Hole represents terrestrial cenote (12.5–7.2 ka BP), restricted marine swamp (7.2–5.7 ka BP) and fully marine lagoonal phases (5.7–0 ka BP) on Lighthouse Reef carbonate platform. Post‐glacial and Holocene sea‐level rise largely controlled the sedimentological, faunal and floral changes

Shallow‐marine mudstone of the Cretaceous Kaskapau Formation in the British Columbia foredeep preserves a 185 m thick record of OAE2. The organic carbon‐isotope and osmium‐isotope excursions can be correlated in detail with other Cenomanian–Turonian boundary sections around the world.

Marine palynology of the Alano di Piave Bartonian–Priabonian Global Stratotype Section and Point, NE Italy [PDF]
Further strengthening the multidisciplinary stratigraphic and paleo-environmental analysis of the Global Stratotype Section and Point (GSSP) Bartonian–Priabonian boundary of the Alano di Piave section (NE Italy), here, we present a data report of a ...

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 ...

In the southwestern Atlantic Ocean, the San Matías Gulf (SMG) is a semi-enclosed coastal ecosystem (40.5°-42.5°S; 63.5°-65.5°W) with considerably greater depths (up to 190 m) than the adjacent continental shelf (~70 m).
