Geological Map of the Iberian Peninsula, Balearic and Canary Islands, scale 1:1,000,000, 1995 edition.
Description
The Geological Map of the Iberian Peninsula, Balearic and Canary Islands or Geological Map of Spain at a scale of 1:1,000,000 is a map developed by the Geological Survey of Spain (IGME) on a cyclical basis since its foundation, being the 1995 version the first to be digitised. This map is an infrastructure of homogeneous and global geological knowledge of a geological unit of continental scale such as the Iberian Peninsula. The map contains the chronolithostratigraphic units with representation of the tectonic structure by means of faults and thrusts. It is also accompanied by two chronolithostratigraphic legends (Peninsula and Balearic and Canary Islands) and the conventional signs. Each of the geological units has an associated description, the dominant rock types and the chronostratigraphic age with precision down to the Flo, when available. There is no difference between the contacts of the map units, all of them being considered as lithological contacts, with the exception of those that are the product of faults. The map is consistent with a topographic base at a scale of 1:1,000,000 prior to the BCN 1000 of the IGN, which is only available in paper format. The geological information on the Iberian Peninsula and the Balearic Islands is in UTM projection, zone 30, Postdam datum. The information on the Canary Islands is in UTM projection, zone 28, datum Pico de las Nieves. The map is distributed free of charge in shape format through the IGME website.
