ResumoThis work represents the first step of the Geological Survey of Colombia - INGEOMINAS in the elaboration of the systematic digital cartography of construction materials, corresponding to the phase of Reconnaissance within the Geological Study, according to the lineaments of United Nations international Framework for the classification of reserves and resources. The study made in geologic plates 130 (Santa Fe de Antioquia), 146 (Western Medellin) and 166 (Jerico), 6000 Km 2 on scale 1:100 000, includes the analysis of the rock units with respect to the lithological characterization, location and physical and chemical behavior to be used like natural aggregate sources - sands, gravel and crushed stone, in the elaboration of concrete of cement portland, masonry mortar, pavements of concrete and asphalt pavements, light aggregates for the use in light concrete and structural clays for the elaboration of roofing tiles, bricks and paving stones. The potentiality of the rock units appears based on the distribution, lithological composition and physical and chemical quality of the materials that compose them. The presentation of the maps becomes in digital format in Arc-View. Parallelly, a synthesis becomes of the existing standards in Colombia on these raw materials.
