Late Miocene to Pliocene stratigraphy of the Kura Basin, a subbasin of the South Caspian Basin: implications for the diachroneity of stage boundaries

, 2015
Relative ages of late Cenozoic stratigraphy throughout the Caspian region are referenced to regional stages that are defined by changes in microfauna and associated extreme (>1000 m) variations in Caspian base level.

Ordovician series and stages in Chinese stratigraphy: steps toward a global usage

Alcheringa: An Australasian Journal of Palaeontology, 2001
The first Chinese Ordovician series was erected by Lee & Chao (1924). Since then, many regional Ordovician series and stage names have been established and mostly published in Chinese. The present study is a review of these regional units with a discussion of their definitions and correlation to the international standard. Among them, the Ichang series,

Coniacian – Maastrichtian calcareous nannofossil biostratigraphy and carbon-isotope stratigraphy in the Zagros Basin (Iran): consequences for the correlation of Late Cretaceous Stage Boundaries between the Tethyan and Boreal realms

, 2014
Calcareous nannofossil biostratigraphy and stable isotope stratigraphy have been investigated in the Shahneshin section of the Gurpi Formation from the Zagros Basin (Iran).

The stratigraphy of the Callovian and Oxfordian stages (Middle-Upper Jurassic) in northern Scotland [PDF]

open access: possibleScottish Journal of Geology, 1975
Synopsis Outcrops of Middle-Upper Jurassic rocks in northern Scotland are restricted to two sedimentary basins. In the east exposures at Brora (Sutherland) and Balintore (Ross-shire) are part of the Moray Firth basin. In the west major exposures at Staffin and in Strathaird (Isle of Skye) belong to the Minch basin.

Stratigraphy of Cenozoic Deposits and the History of the Latest Stage of Geological Development of the Zaisan Depression (Eastern Kazakhstan)

Стратиграфия, 2023
The Zaisan Basin is a unique geological structure that preserves a most complete sedimentary archive of late Mesozoic through most of the Cenozoic era. A century of studies brought very rich data on the stratigraphy and geological history of the Zaisan sedimentary sequence.

Strontium isotope stratigraphy of the Oligocene‐Miocene Otekaike Limestone (Trig Z section) in southern New Zealand: Age of the Duntroonian/Waitakian Stage boundary

, 2000
The Otekaike Limestone Trig Z sequence in southeastern South Island, New Zealand, is the type section for the local Waitakian Stage, and contains the Duntroonian/ Waitakian Stage boundary, previously thought equivalent to the Oligocene/Miocene Epoch ...

The glacial stratigraphy of lowland southern and eastern Britain: temperate-stage deposits at Morston and Kirmington

Proceedings of the Yorkshire Geological Society, 2007
SUMMARY The recent suggestion that no warm-stage deposits have yet been found separating glacial sediments in lowland southern and eastern Britain is shown to be incorrect. At Morston, on the coast of north Norfolk, an ancient beach succession with a temperate pollen assemblage rests upon till closely comparable with the Marly Drift, usually ...

Integrated stratigraphy across the Aptian-Albian boundary in the Marnes Bleues, at the Col de Pré-Guittard, Arnayon (Drôme), and at Tartonne (Alpes-de-Haute-Provence), France: a candidate Global Boundary Stratotype Section and Boundary Point for the base of the Albian Stage

, 2000
The history of definition of the Aptian-Albian boundary is reviewed with particular reference to the ammonite schemes of Brinkmann (1937), Breistroffer (1947), Casey (1961a, 1996, 1999), Kemper (1982), Owen (1996, 1999), and Ruffell & Owen (1995).
