Testing High-Voltage Electrical Discharges in Disintegrating Claystone for Isotopic and Mineralogical Studies: An Example Using Opalinus Claystone

Clays and Clay Minerals, 2017
AbstractThe radiogenic isotope systematics of clay minerals are complex because of the intimate mixture of minerals from different origins such as detrital and authigenic sources. An important aspect of dating clays is the primary sample preparation and disintegration method. In the present study, a sample of weakly deformed Opalinus claystone from the

An insight into grain interaction in bentonite/claystone mixtures

Acta Geotechnica, 2022
This paper investigates the swelling mechanism of Callovo-Oxfordian (COx) claystone grain in its mixtures with bentonite which are potential candidate for engineered barriers in the French high-level radioactive waste disposal.

On the porosity of COx claystone by gas injection

Microporous and Mesoporous Materials, 2017
An original method for porosity assessment is proposed, which uses gas injection into dried or partially-dried claystone under hydrostatic stress. For these materials, accurate porosity assessment is complicated by the interactions of clay with water, by its crack sensitivity and by the fineness of the pores (ranging from a few nm to hundreds of nm ...
