Miocene deep water agglutinated foraminifera from Viosca Knoll, offshore Louisiana (Gulf of Mexico) [PDF]
, 2004 An exploration well from the Gulf of Mexico, Amoco Viosca Knoll-915, has been studied in order to document the Neogene foraminiferal assemblages. Ditch cuttings samples from the Amoco V.K.

Downcurrent variation in submarine channel‐fill architecture from the shelf to upper slope
Sedimentology, EarlyView.ABSTRACT The transition between the shelf and the upper slope is often considered an area of sediment bypass, where steeper gradients increase flow velocities and maintain particles in suspension. In addition to transferring sediments into deeper basins, upper‐slope areas can also host channelised submarine deposits.

Foraminiferal morphogroups of the Early–Middle Cretaceous succession in northeastern Rafsanjan and their significance as palaeoenvironmental bioindicators [PDF]
Journal of Stratigraphy and Sedimentology ResearchesForaminiferal morphogroups reveal their responses to palaeoenvironmental and palaeoecological changes. The foraminiferal morphogroups of the early-mid Cretaceous in northeastern Rafsanjan have been investigated with an interest in palaeoenvironmental ...

Terra Nova, EarlyView.ABSTRACT During the Middle Miocene Badenian Salinity Crisis (BSC), extensive evaporites formed across different tectonic settings in the Central Paratethys. Limited age constraints hamper evaporite correlation and identification of driving mechanisms. Here, we use U–Pb dating of zircon by LA‐ICP‐MS from tephra overlying the Tuzla Basin evaporites.

Ecology and EvolutionForaminifera is the most important temperature proxy of the ocean on long time scales. However, the absence of temperature‐controlled experiments at different water depths hinders the advancement of paleotemperature reconstruction with foraminifera from ...

Exploring the controls on element ratios in middle Eocene samples of the benthic foraminifera Oridorsalis umbonatus [PDF]
Culturing studies and empirically based core top calibrations have been used to infer that elemental ratios in benthic foraminifera can be used as proxies to reconstruct past variations in bottom water temperature and saturation state (Δ [CO32 ...

Biostratigraphy of the Ruteh Formation at Harijan section (Central Alborz) northern Iran using foraminifera and conodont [PDF]
, 2009 In order to study the fossil contents of the Ruteh Formation for biostratigraphical purposes, the 200 meters thick section was sampled at Harijan section, Central Alborz. The sequence is mainly made up of limestone and shale's.
