Pore gas connectivity analysis in Callovo-Oxfordian argillite

Applied Clay Science, 2008
Abstract Deep geological barriers, such as Callovo-Oxfordian argillites, display suitable characteristics for a high level radioactive waste repository. Their low permeability is a key parameter to retain radionuclides locally. However, once the system is closed, gases produced by corrosion of the waste canisters can represent a risk to the ...

HTO Diffusion in Oxfordian Limestone and Callovo-Oxfordian Argillite Formations

MRS Proceedings, 2004
AbstractDiffusion coefficients and accessible porosities for HTO were measured on 30 samples from the Andra Underground Rock Laboratory in Meuse/Haute-Marne (France) using the through diffusion technique. Two distinct geological formations were studied: Oxfordian limestone and Callovo-oxfordian argillite between 166 and 477 m depth.

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.

Diffusion of anionic species in Callovo-Oxfordian argillites and Oxfordian limestones (Meuse/Haute–Marne, France)

Applied Geochemistry, 2008
Abstract Diffusive parameters of tritiated water (HTO) and several anionic tracers (36Cl−, 125I−, 35 SO 4 2 - and 75 SeO 3 2 - ) were determined in the Callovo-Oxfordian argillite formation (Meuse/Haute–Marne, France), and also in the Oxfordian limestone formation, located just above.

The water retention properties of the Callovo-Oxfordian claystone

International Journal of Rock Mechanics and Mining Sciences, 2013
Abstract A possible option for the disposal of high level long lived radioactive waste is to store the waste in galleries excavated at great depth in clays or claystones. In such conditions, the walls of the galleries will be successively subjected to desaturation induced by ventilation followed by resaturation once the galleries are closed.

Investigating the Microstructure of Compacted Crushed Callovo-Oxfordian Argillite

Soil Behavior and Geo-Micromechanics, 2010
Some aspects of the macroscopic geotechnical behavior of compacted soils are highly related to their microstructure. This paper presents a qualitative and quantitative microstructure investigation of compacted samples made up of crushed Callovo-Oxfordian argillite.
