Many countries, as among others France, Belgium and Switzerland, are facing the issue of finding a proper solution to store radioactive waste coming from nuclear power plants. The possibility them in underground tunnels is largely considered investigated. In Andra (Agence Nationale pour la gestion des Déchets RAdioactifs) selected Callovo-Oxfordian clay rock situated Meuse/Haute Marne site betw...

Quarry 9 is among the richest microvertebrate localities in the Morrison Formation, having thus far produced the remains of dozens of Late Jurassic taxa. Because this lenticular claystone deposit records such a high diversity of contemporaneous species, it provides an exceptionally detailed view of their paleoecology and local paleoenvironment. In this study, we reexamined the entire Quarry 9 c...

A series of gas injection tests on Callovo-Oxfordian (COx) claystone from the Bure underground research laboratory (URL) in France were carried out at British Geological Survey (BGS). The performed using a triaxial apparatus specifically designed to capture small volumetric strains induced by injected flow and consequent material dilatancy. long-duration experiments monitored throughout. Measur...
