The brittle and ductile behaviours correspond respectively to discontinuous deformation and continuous deformation (§2.1.1, 2.2.2. and fig.2.2). Natural manifestations of discontinuous deformation include faults and fractures in which the nature of the displacement is different. First we shall consider those discontinuous structures caused by no or little displacement parallel to the surface: joints, tension fractures, stylolitic joints (which are not due to brittle deformation but are associated with the preceding structures), then the faults which correspond to large displacements along their surface. The associations made by these different structures and their relations with the states of stress will also be considered.
