Description: The isopachs are represented in two forms:Depth to the base of Cretaceous in Meso-Cenozoic basins (in km); and depth to basement in pre-Cretaceous basins (in km). The data for basins inside the continent or along the continental margins were compiledfrom maps furnished by PETROBRAS-Petróleo Brasileiro S.A. / Petrobras-Brazilian Petroleum Company, SEGEMAR- Servicio Geológico Minero Argentino / Geological and Mining Survey of Argentina and various other sources, improved and adjusted.For the offshore area, these contour lineswere derived from the digital total-sediment-thickness database for the world’s oceans and marginal seas, compiled by the NOAA (National Oceanic and Atmospheric Administration, USA) and gridded with a spatial resolution of 5 arc-minutes. The isopachs were simplified, consolidated and adjusted along the continental margins to produce this unified shape.

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.

Description: The bathymetric digital elevation model, values in meters, was obtained by processing of the GEBCO_08 Grid, release in October 2010 with a spatial resolution of 30 arc-seconds. Data range from 0 to -8000 meters in depth and were classified into five intervals. The first one from 0 to -200, the second from -200 to -2,000 and the other at intervals of 2,000 meters. They are represented by bright bluish bands along the continental shelfs and continental margins. The GEBCO_08 grid was also used to generate the greyscale shaded relief image that composes the map background. Source of grid data: www.gebco.net.
Description: To prevent overload the printed map, just a few submarine physiographic features were noted: Rises (Rio Grande, Malvinas and Northeast Georgia and the Pirie Bank), Aseismic Ridges (North Scotia, Malpelo, Nazca, Juan Fernandez, Cocos, Coiba, Carnegie, North Brazilian, Paraiba and São Paulo), Seamount Chains (Vitoria-Trinidad and Jean-Charcot), and Abrolhos Volcanic Complex.Interpreted Offshore Lavas from SDRs (Seaward Dipping Reflectors) and Island Arc are also represented in this shape.
