Early to middle Miocene foraminifera from the deep-sea Congo Fan, offshore Angola [PDF]

, 2008
Analysis of a 630m section of an exploration well penetrating the distal part of the Congo Fan (~2000m water depth) yielded high abundance and diversity assemblages of agglutinated and calcareous benthic foraminifera.

Dual clumped isotopes in foraminiferal calcite reveal kinetic bias in some species

Communications Earth & Environment
Clumped isotope (∆47) analyses of foraminifera provide a powerful means to reconstruct upper and bottom water temperatures, independent of seawater δ18O and elemental composition.

Tectonic Forcing of Diachronous Salt Deposition During the Badenian Salinity Crisis Revealed by U–Pb Dating of Tephra Overlying Tuzla Basin Evaporites

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.

Sedimentation environment of the Cojimar Formation (Havana province) based on benthic foraminifera

Minería y Geología, 2022
Cojímar Formation, —Lower Miocene (upper part) to Middle Miocene (lower part)—, is a unit in Western Cuba well known for its extensive development and exposure outcrops. It has been widely used in bioestratigraphic studies.

Study of current benthic foraminifera as environmental bioindicators in the mediterranean coasts, northwest Morocco [PDF]

E3S Web of Conferences
In this project, we introduce a novel methodology for analysing the environmental conditions in the coastal area of Martil (Tétouan, Morocco) using benthic foraminifera as bio-indicators of marine ecological status.

Ecological significance of benthic foraminifera: 13C labelling experiments [PDF]

Marine Ecology Progress Series, 2000
We examined the ability of foraminifera in taking up freshly deposited algal carbon in intertidal estuarine sediments. Lyophylized C-13-labelled axenic Chlorella was added to intact sediment cores containing natural benthic biota. The response of the system as a whole was rapid; similar to 5% of the added carbon was respired to CO2 within 6 h. Bacteria

Response of deep-water agglutinated foraminifera to dysoxic conditions in the California Borderland basins [PDF]

, 1995
Analysis of agglutinated benthic foraminifera from surface samples collected in the San Pedro and Santa Catalina Basins reveals a predictable relationship between the proportions of morphogroups with decreasing bottom water oxygen levels and with the ...

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.

Evaluating the utility of B/Ca ratios in planktic foraminifera as a proxy for the carbonate system : a case study of Globigerinoides ruber [PDF]

, 2015
This research was funded by NERC, Grant Number: NE/D00876X/2.B/Ca ratios in foraminifera have attracted considerable scientific attention as a proxy for past ocean carbonate system.
