Journal ArticleDOI
Analysis of the internal structure of rocks and characterization of mechanical deformation by a non-destructive method: X-ray tomodensitometry
TL;DR: In this article, the relationship between radiological density and porosity is quantified for limestones and sandstones, and spatial variations in the values of the radiological densities measured on rock core specimens that are deformed and fractured in a triaxial cell are then related to the intensity of experimental volumetric deformation.
Mineralogy, texture and porosity of Callovo-Oxfordian argillites of the Meuse/Haute-Marne region (eastern Paris Basin)
TL;DR: The texture and porosity of Callovo-Oxfordian argillites, coming from the Meuse/Haute-Marne region, have been studied at different scales using borehole and laboratory measurements to more spot-like qualitative and quantitative analyses.
Journal ArticleDOI
Influence of interlayer cations on the water sorption and swelling-shrinkage of MX80 bentonite
TL;DR: In this article, the effects of the cation saturation (Mg+, Ca+, Li, Na+, and K+) on the swelling-shrinkage behavior of the MX80 bentonite was investigated.
Journal ArticleDOI
Pore-throat characterization in highly porous and permeable sandstones
TL;DR: In this article, a series of empirical equations for constructing a partial pore-aperture-size distribution curve from routine core analysis for the highly permeable Nubia sandstones in their type section in southern Egypt was introduced.
Journal ArticleDOI
Experimental and theoretical deformation of ice-rock mixtures : Implications on rheology and ice content of Martian permafrost
TL;DR: In this article, constant load triaxial tests are conducted at differential stresses of 1.9-8.5 MPa, confining pressure of 12 MPa and temperature of 263 K in order to determine experimental limits on the proportion of ice in the Martian subsurface.
