MAGNA 50 - Geological map of Spain, scale 1:50.000

The National Geological Map (MAGNA in Spanish), was conducted between 1972 and 2003 by the Spanish Geological Survey (IGME). It is distributed in 1: 50.000 sheets (1:25.000 in the particular cases of the Canary Islands, Ibiza-Formentera, Menorca, Ceuta and Melilla). In the Geologic Map the nature of the materials (rocks and sediments) appearing on the terrestrial surface are represented, its spatial distribution and the geometric relations between the different cartographic units. A geologic cartographic unit is the grouping of one or several lithologies within a common age interval, that has a representation in the map to a defined scale or resolution. Each cartographic unit, as well as the different geologic structures, are displayed on the map with their own simbology. The representation of these units on top the topographic map provides some three-dimensional information that is completed with other geological data and geological sections, stratigraphic profiles, boreholes, etc. The map legend is a pictogram representing the spatial relationship between the different cartographic units (chronology, superposition, geometric relationship, lateral facies changes, etc.). It also includes structural, hydrogeological and geological location schemas of the sheet within its regional level.
