Introduction Faults are zones of weakness in the brittle part of the lithosphere, along which movement can take place in response to stress. When faults undergo displacement, depending on geological and structural conditions, deformation markers can be formed on the fault surface based on the displacement of rock layers. But also, most faults are represented by certain geological features such as drainage patterns, lineaments (linear features) and lithological contacts between rock units within the rocks (Hobbs, 1904 and 1911) who recognized the existence of linear geomorphic features and interpreted them as displacement of the earth’s crust. Lineaments are linear features at the Earth’s surface, generally related to sub- surface phenomena. Generally, lineaments are related to large fractures and faults where their orientation and number give an idea of the fracture pattern of the rocks (Arlegui and Soriano, 1998). In recent years, lineaments
