Fig. 16From: Microstructural characterization of natural fractures and faults in the Opalinus Clay: insights from a deep drilling campaign across central northern SwitzerlandConceptual structural geological sketches for the deformation style of Opalinus Clay for the far eastern and western parts of the study area. Note that these sketches focus on m-scale zones within the over 100Â m thick formation that is elsewhere often free of natural fractures over several tens of mBack to article page
