Clay mineral-carbonate relations in sedimentary rocks
American Journal of Science, 1959Mineralogical investigation of modern sediments off the coast of Peru and Chile reveals the presence of volcanic glass in many samples. The glass is commonly devitrified in sea water to fine aggregates of minerals, including calcite and kaolinite. The textural relations of these two phases suggest attainment of chemical equilibrium, and thus a thermo ...

Deformation of clay rock under THM conditions
Geomechanics and Tunnelling, 2015AbstractAs a potential host rock for deep geological disposal of radioactive waste, the Callovo‐Oxfordian and Opalinus clay rocks have been extensively investigated in the laboratory with respect to deformation under various thermo‐hydro‐mechanical conditions: (1) stresses covering the range from the initial lithostatic state to redistributed levels ...

Response of Clay Rock to Moisture Change
2017Various kinds of laboratory experiments were carried out on the Callovo-Oxfordian and Opalinus claystones to investigate response of clay rock to moisture change, including swelling and shrinking with variations of the environmental humidity, stress-bearing capability of bound porewater or buildup of swelling pressure, influence of water content on the

Diffusion in crushed rock and in bentonite clay: Dissertation
1994Diffusion theories for porous media with sorption are reviewed to serve as a basis for considering diffusion in simple systems like sand or crushed rock. A Fickian diffusion and linear sorption model is solved both by analytical Laplace transform and Green's function methods and by numerical methods, and then applied to small-scale experiments for ...
