Facies, cycles, and controls on the evolution of a keep‐up carbonate platform (Kimmeridgian, Swiss Jura) [PDF]

open access: yesSedimentology, 2005
During the Late Jurassic, accelerated ocean-floor spreading and associated sea-level rise were responsible for a worldwide transgression, which reached its maximum in the Late Kimmeridgian.

A palaeoclimate model for the Kimmeridgian

Palaeogeography, Palaeoclimatology, Palaeoecology, 1992
Abstract Most attempts at using numerical General Circulation Model (GCM) to simulate Mesozoic climates have studied the Late Cretaceous and have focused on the enigmaof apparently equable global climates. However, this climate regime lasted throughout the Mesozoic and it is of interest to examine other periods.

Integrated stratigraphy and palaeoenvironmental interpretation of the Upper Kimmeridgian to Lower Berriasian pelagic sequences of the Velykyi Kamianets section (Pieniny Klippen Belt, Ukraine)

Palaeogeography, Palaeoclimatology, Palaeoecology, 2019
A continuous sedimentary and stratigraphic record of Late Kimmeridgian – Early Berriasian age is presented from the pelagic succession from the eastern part of the Pieniny Klippen Belt (Velykyi Kamianets section, Ukraine). The studied section, 26-m-thick,

Upper Kimmeridgian stratigraphy of Aylesbury, Buckinghamshire

Proceedings of the Geologists' Association, 1991
Field work carried out in Aylesbury in 1987 demonstrated that the Upper Kimmeridge Clay attains 31 m thickness and has a minor non-sequence at its base. The sequence fits well with the trend of gradual thinning southwestwards, from the relatively thick development of the Wash area to the thin sequence deposited over the Oxford Shallows.

Climatic fluctuations and seasonality during the Kimmeridgian (Late Jurassic): Stable isotope and clay mineralogical data from the Lower Saxony Basin, Northern Germany

Palaeogeography, Palaeoclimatology, Palaeoecology, 2019
In previous palaeoclimatic models, the Kimmeridgian stage has been defined as a typical greenhouse-time interval with weak latitudinal gradients. However, palaeoclimatic information based on biogenic low-Mg calcite δ18O for the Kimmeridgian is still ...

Late Jurassic (Kimmeridgian) sea lilies (Crinoidea) from central Poland (Łódź Depression)

Annales de Paléontologie, 2019
Upper Jurassic (Kimmeridgian) limestones of central Poland (southern border of the Łodź Depression) are in places extremely rich in crinoid remains. These latter are represented by very well preserved columnals/pluri-columnals, isolated brachials and ...

Kimmeridgian palaeogeography and basin evolution of northeastern Iberia

Palaeogeography, Palaeoclimatology, Palaeoecology, 2001
Abstract Two sedimentary basins were developed during the Kimmeridgian in the northeastern part of Iberia: the Basque-Cantabrian Basin, to the northwest, and the Iberian Basin, to the east. These basins were mainly filled by carbonates deposited in a shallow epicontinental sea that was connected to the open marine realms of both the North Atlantic ...

PROTOGLOBIGERINIDS OF THE EARLY KIMMERIDGIAN OF THE JURA MOUNTAINS (FRANCE)

The Journal of Foraminiferal Research, 2013
A detailed investigation of the protoglobigerinids from the lower Kimmeridgian section at Les Bouchoux, Jura Mountains, France, has been carried out by study of thin sections and acetolysis extractions. This predominantly indurated carbonate succession represents peri-platform, hemipelagic deposits, well-dated by ammonites.

Towards a unified Kimmeridgian Stage

Petroleum Geoscience, 1995
Considerable confusion exists in the interpretation of the term Kimmeridgian. As the Kimmeridge Clay Formation is the principal source rock in the northern North Sea, this confusion has important implications for geoscientists working there. The source of the confusion is historical, but the introduction of the Bolonian Stage as a local secondary ...
