Description: Concerning the South American Platform, previously called the Brazilian Shield, the work began with the use of the digital files (shapefiles) of the GeoSGB of CPRM, at 1:1.000.000 scale, containing the attributes of the Brazilian lithostratigraphic units. The latest geological information available for the main geological units was compiled for the map. Additionally, for Colombia, Venezuela, Guyana, Suriname, French Guiana, Bolivia, Paraguay and Uruguay, all available information was integrated in the newly built geological database. SEGEMAR in Argentina compiled the information for the Andean sector based on tectonic data of the Metallogenetic Map of South America (2005, 1:5 M scale) published by SEGEMAR under the aegis of CGMW, ASGMI and UNESCO. The compilation involved liaison with colleagues from all Andean countries – Chile, Peru, Ecuador, Bolivia, Colombia and Venezuela. All information was adjusted on Landsat TM images and SRTM of South America and complemented with subsequent updates and suggestions received from regional specialists.This enabled the preparation of a new georeferenced base map of South America, carried out by CPRM and SEGEMAR. The geological polygons were then interpreted and classified according to a unified legend for the South American Platform and the Andean region, in order to enable the discrimination of different tectonic settings and ages. Three essential attributes were developed to allow the application of that legend: (1) age of the last tectonic event that affected the area; (2) nature of the tectonic setting; and (3) age of formation of the rocks. The attributes of about 8,000 individual polygons were included in the final database. Owing to the scale of the map, 1:5.000.000, many of the regionally mapped geologic and tectonic units could not be included because of their relatively small outcrop areas.
