Anomalously cool clumped isotope temperatures in tropical lagoon carbonates

open access: yesThe Depositional Record, EarlyView.
Carbonate clumped isotopes were used to reconstruct paleoclimate from lagoon sediments in the central tropical Pacific. Results were anomalously cool compared to modern measurements and other paleoclimate records. This study highlights the important of understanding carbonate facies and depositional environments in interpreting clumped isotope results.

Eustatic and tectonic controls on mixed carbonate‐siliciclastic ramp deposits in the South Pyrenean foreland basin: The Eocene Alveolina Limestone

open access: yesThe Depositional Record, EarlyView.
The lower Eocene Alveolina Limestone records the global early Eocene transgression, but is equally affected by tectonic movements of the Montsec active thrust located in its hangingwall. Tectonic movements and the early Eocene transgression facilitated a detrital provenance shift in the southern Pyrenean foreland from a southern provenance in the ...

Trace elements, rare earth elements and isotopes of poorly preserved fossils from lower Cretaceous carbonates (Eastern Black Sea): Implications for early diagenetic alteration

open access: yesThe Depositional Record, EarlyView.
Analysing Rare Earth Elements (REEs) and other trace elements together with stable isotope data in poorly preserved belemnites can provide valuable insights into early diagenetic pathways, water‐interaction processes, and even potential redox conditions.

A late Holocene sea-level curve for the east coast of South Africa

open access: yesSouth African Journal of Science, 2014
South Africa’s extensive and topographically diverse coastline lends itself to interpreting and understanding sea-level fluctuations through a range of geomorphological and biological proxies.

Stratigrafické a paleoekologické vyhodnotenie asociácie dierkavcov z vrtu HC-4 (Holíč, Viedenská panva) [PDF]

open access: yesGeologické práce. Správy, 2021
HC-4 well was drilled nearby the Holíč water reservoir well in 2020 by Aqua-Geo company to build a new water reservoir. This work aims to interpret foraminifera associations from the ditch cuttings of the Neogene (Sarmatian) sediments of the Holíč and ...

Miocene deep water agglutinated foraminifera from Viosca Knoll, offshore Louisiana (Gulf of Mexico) [PDF]

open access: yes, 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.

Stratigraphy of diagenesis: Limestone–dolomite cycles in a mid‐ramp setting, Miocene Arcadia Formation, South Florida, USA

open access: yesThe Depositional Record, EarlyView.
The data and interpretations of this study are used to test the proposal by Goldhammer et al. that a ‘stratigraphy of early diagenesis’ is operational in carbonate depositional systems. What this means is that distinct mineralogical and geochemical changes to rock and sediment occur associated with external controls, such as the rise and fall of sea ...

Mn Incorporation in Large Benthic Foraminifera: Differences Between Species and the Impact of pCO2

open access: yesFrontiers in Earth Science, 2020
Element concentrations of calcite precipitated by foraminifera reflect chemical and physical properties of seawater and can therefore be used to reconstruct (paleo-)environmental conditions.
