Magnetostratigraphic correlation of the Oxfordian–Kimmeridgian boundary

Earth and Planetary Science Letters, 2010
A magnetic polarity pattern for Boreal and Sub-Boreal ammonite zones of the Upper Oxfordian to Lower Kimmeridgian was established and confirmed in four British sections, including the proposed Global Boundary Stratotype Section and Point (GSSP) on the Isle of Skye (Scotland) to define the base of the international Kimmeridgian Stage.

Kimmeridgian-Volgian Aporrhaidae (Stromboidea: Gastropoda) of the Russian Platform

Paleontological Journal, 2014
Kimmeridgian-Volgian Aporrhaidae from European Russia are described for the first time. They are referred to three genera, including two new genera, Undoriptera gen. nov. and Volgacheilus gen. nov. with three new species, Undoriptera tridactylus sp. nov., Volgacheilus rogovi sp. nov., and Dicroloma tenuistriata sp. nov.

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.

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.

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 ...

Biostratigraphy of the highest Kimmeridgian and Lower Volgian in Poland

Geobios, 1994
Abstract In Poland, the ammonite succession in several continuous and expanded sections makes it possible to recognize the Eudoxus and Autissiodorensis Zones in the Upper Kimmeridgian as well as the Klimovi, Sokolovi, Pseudoscythica and Tenuicostata Zones in the Lower Volgian, and to reconstruct an evolutionary lineage leading from Discosphinctoides ...
