Abstract—The geological context of North East Constantine is very complex. This region is characterized by a superposition of several thrust sheets, reflecting a geological and tectonic evolution during Mesozoic and cenozoic. In addition, there is a wide variety of sedimentary rocks, such as limestones, sandstones, clays and marls. A physico-chemical characterization of the lithological diversity would be a great contribution to the different users and managers at a time when the region is under major socio-economic development projects. This study proposes a first phase, a physico-chemical characterization of limestones and sandstones (by optical microscopy, XRD, SEM/EDS and porosimetry), and a reflection on the development of mechanical properties of these materials in a second phase. Preliminary results of this multidisciplinary study (obtained by various analytical techniques) show good agreement on the existing phases.
Index Terms—Limestone, porosity, sandstone, SEM /EDS.
