Each geological object is characterized by a series of attributes.

The information in the Geological map 1:50,000 is organized into four groups of geological objects: faults and folds, contacts (sedimentary, metamorphic, igneous and hydrothermal) and geomorphological elements, geological units and anthropic deposits.Įach grouping of geological objects, although most cases correspond to bodies or surfaces in a 3D space, in distribution files (2D shapes) are represented according to the geometry associated (polygons, lines and points). That is why there may be divergences between the coastline of this geological information and the latest versions of cartographic bases of the ICGC. The geological information was made with reference to the cartographic base available at the time of the elaboration.

This version of the previous distributions supports a new distribution data model and incorporates improvements in both attributes and geometries. The geodetic reference system of the distributed data is ETRS89 UTM31N.
