Lower Cambrian Saint Petersburg blue clays and their fissuration. Implication for underground stages

Résumé

The Lower Cambrian Saint Petersburg blue clays are composed of predominant illite and chlorite, sometimes accompanied by kaolinite. The < 0.1 μm fraction has a high content of illite-smectite mixed layers. Particle-size distribution is more than 50% of clay particles and about 30% of silts. These blue clays correspond to plastic (and soft) clays; they may be compared to the Callovian clays of Bure (France), where storage of natural waste is envisaged. © 2002 Académie des sciences/Éditions scientifiques et médicales Elsevier SAS.
