Suction effects in deep Callovo-Oxfordian claystone

Géotechnique Letters, 2014
An experimental programme was carried out with the aim of investigating suction effects in a specimen of Callovo-Oxfordian claystone extracted at great depth (479 m). A specimen that was saturated in an oedometer with limited swelling exhibited significant swelling and desaturation upon quick unloading at constant water content.

The Thermal Volume Changes of the Callovo–Oxfordian Claystone

Rock Mechanics and Rock Engineering, 2013
There are very few data on the thermoplastic behaviour of claystones, while their knowledge is necessary in understanding long-term behaviour of high-level radioactive waste confining systems. In this paper, a number of thermomechanical parameters of the Callovo–Oxfordian claystone, the possible host rock of radioactive waste in France, are presented ...

Oxfordian perisphinctid ammonites from Chacay Melehué, Argentina

Paläontologische Zeitschrift, 2006
A significant assemblage of Oxfordian perisphinctids was collected at Chacay Melehue, Neuquen, Argentina. It is composed of well preserved specimens belonging to the family Perisphinctidae:Perisphinctes aff.promiscuus Bukowski (Perisphinctinae),Tenuisphinctes herreroduclouxi (Leanza) (Perisphinctinae), andSubvinalesphinctes pseudokranaus n. sp.

Upper Oxfordian palaeogeography of southern England

Palaeogeography, Palaeoclimatology, Palaeoecology, 1968
Abstract The Upper Oxfordian of southern England consists of a variable series of clays, sands and limestones known as the Corallian Beds. Six sedimentary facies are distinguished: (1) phyllosilicate clay facies (background sedimentation to other facies); (2) quartz sand facies (intertidal sands); (3) coralline facies (coral patch reefs and ...

Gas Migration into Low Permeability Callovo-Oxfordian Argillite

2nd EAGE International Conference on Fault and Top Seals - From Pore to Basin Scale 2009, 2009
Gas migration into argillaceous formations is an important issue to evaluate the perturbation induced by gas in an underground radioactive waste repository. The mechanisms controlling gas entry and flow into clay media are not fully understood yet and have to be investigated.

Oxfordian Sedimentation in Western Interior, USA: ABSTRACT

AAPG Bulletin, 1972
Upper Jurassic Oxfordian sediments of Wyoming, Montana, and eastern Idaho were deposited in part of an elongate inland seaway extending southward from the present Arctic. This seaway contained a complex of tectonic elements which influenced significantly the geographic distribution of depositional environments.

Oxfordian Sedimentation in Western Interior United States

AAPG Bulletin, 1974
Upper Jurassic (Oxfordian) sediments of the western interior United States were deposited in part of an epicontinental seaway which extended south from the present arctic. This seaway contained a complex of tectonic elements which influenced significantly the geographic distribution of depositional environments.
