Reduced sediment accumulation rate enhances early marine diagenesis of periplatform sediments

The Depositional Record, Volume 12, Issue 2, April 2026.
The influence of reduced sediment accumulation rate on early marine burial diagenesis was investigated in sediments collected by ODP Leg 133. Results show that low sediment accumulation rates can produce substantial and asynchronous shifts in stable carbon isotope ratios across a slope transect without the development of sedimentological indicators of ...

Diversity and distribution of Cambrian acritarchs from the Siberian and East-European platforms - a generalized scheme

Carnets de Géologie, 2005
The study of acritarchs in Russia was initiated by Naumova and Timofeev in the early 50s. Their initial results showed the high potential of these microfossils for biostratigraphy and was followed by a remarkable degree of research activity in the 70s ...

Middle Ordovician conodonts and graptolites at Los Cauquenes range, central Precordillera of San Juan, Argentina [PDF]

, 2013
The Ordovician System is superbly represented in the Precordillera of western Argentina, at the Andean foothills. During the Middle Ordovician, an important paleogeographical rearrangement of depocenters and source areas took place associated with the ...

The Permian–Triassic transition in Türkiye: New insights and 3D outcrop models for accessible, reproducible and sustainable fieldwork

The Depositional Record, Volume 12, Issue 2, April 2026.
We studied the Permian–Triassic successions of south‐western Türkiye at five locations, synthesised sedimentological and palaeontological data, putting it into a consistent stratigraphic framework and incorporating 3D digital outcrop models. Abstract The Permian–Triassic transition is characterised by major environmental changes and the largest known ...

Foraminifera Distribution Patterns within Sequence Stratigraphy (A Case Study: Blora Area and Surroundings/Low Latitude Area)

Journal of Mathematical and Fundamental Sciences, 2019
Sari. Analisis stratigrafi sikuen memerlukan data yang menyeluruh dari berbagai disiplin ilmu geologi, termasuk biostratigrafi. Secara hipotesis, biostratigrafi (foraminifera) dapat dijadikan alat untuk mengidentifikasi sikuen.

Microbiostratigraphy of the Berriasian–Valanginian boundary in eastern Crimea: foraminifers, ostracods, organic-walled dinoflagellate cysts

Geologica Carpathica, 2017
Thorough study of foraminifers, ostracods and dinoflagellate remnants from the Zavodskaya Balka and Koklyuk sections helps to characterize the detailed biostratigraphic division of the Berriasian / Valanginian boundary sequence in the Feodosiya district ...

Holocene palaeoenvironmental reconstruction of sea level, coastal and vegetation changes along the southern Solway Firth, United Kingdom

Journal of Quaternary Science, Volume 41, Issue 3, Page 419-432, April 2026.
ABSTRACT Holocene relative sea level (RSL) changes were reconstructed from four sites along the less‐studied southern Solway Firth. A multiproxy approach, including lithostratigraphical and biostratigraphical analyses, combined with radiocarbon dating, produced ten sea level index points (SLIPs).

Remarks on the type locality and current status of the foraminiferal species Rzehakina epigona (Rzehak, 1895) [PDF]

, 2001
A likely topotype locality is proposed for Rzehakina epigona. As the type specimen of Silicina epigona Rzehak, 1895 is assumed to be lost, we undertook a search for new material in the type area, Zdounky village in Moravia. A single locality provided a

Morphology, biostratigraphy, and evolution of PliocenePleistocene diatoms Proboscia barboi.. [PDF]

, 2019
Proboscia barboi and Proboscia curvirostris are two important diatom biostratigraphic markers from the high latitudes of the North Pacific and North Atlantic Oceans, dating back to the Pliocene-Pleistocene time.

From Ice to Isolation: A geochemical reconstruction of the palaeoenvironmental evolution of Gairloch, NW Scotland (UK), since the Last Glacial Maximum

Journal of Quaternary Science, Volume 41, Issue 3, Page 507-519, April 2026.
ABSTRACT Complex relative sea‐level (RSL) changes are associated with the deglaciation of the British and Irish Ice Sheet (BIIS). Sediment archives from Loch Bad na h‐Achlaise, an isolation basin in NW Scotland, UK, span Late Glacial to Holocene time and record sea‐level change and ice proximity via a geochemical and biostratigraphic multiproxy ...
