p.162: The second one [Calcaires plaquetés] is composed of platy micritic limestones, whose faunal content can be restricted and where dolomite occurrence is common, as well as that of organic matter, which can form even bitumen laminites in a few places (Orbagnoux, France, Davaud et al. 2014). This unit is mechanically more easily deformed and kinks are observed close to major fault zones (Charollais et al. 2013; Donzeau et al. 1998; Widmer 2001).
