II.  INTRODUCTIONTOP of Report
This digitally compiled map includes geology, geologic provinces, and oil and gas fields of South America. The map is part of a worldwide series on CD-ROM by World Energy Project released of the U.S. Geological Survey . The goal of the project is to assess the undiscovered, technically recoverable oil and gas resources of the world and report these results by the year 2000. For data management purposes the world is divided into eight energy regions corresponding approximately to the economic regions of the world as defined by the U.S. Department of State. South America (Region 6) includes Argentina, Bolivia, Brazil, Chile, Columbia, Ecuador, Falkland Islands, French Guiana, Guyuna, Netherlands, Netherlands Antilles, Paraguay, Peru, Suriname, Trinidad and Tobago, Uruguay, and Venezuela.

Each region is then further divided into geologic provinces on the basis of natural geologic entities and may include a dominant structural element or a number of contiguous elements. Some provinces contain multiple
genetically related basins. 

Geologic province boundaries for the South America are delineated using data from a number of geologic maps, and other tectonic and geographic data (see References). Offshore province boundaries are defined by the 4000 meter bathymetric contour. Each province is assigned a unique number; the first digit is the region number. It is attempted to number the provinces in geographical groups; onshore, offshore, and combined on and offshore. The list of the provinces sorted by Code is shown in Adobe Acrobat samgeo.pdf file (see section V below).

Oil and gas field data from Petroconsultants International Data Corporation worldwide oil and gas field database are allocated to these provinces. The geologic provinces are being further subdivided into petroleum systems and assessment units in order to appraise the undiscovered petroleum potential of selected provinces of the world.

Specific details of the data sources and map compilation are given in the metadata file on this CD-ROM. Smaller stratigraphic subdivisions of Phanerozoic rock are combined to simplify the map and to maintain consistency with other maps of the series. Precambrian rocks are undivided. Oil and gas field markers represent field centerpoints published with permission from Petroconsultants International Data Corp.,1996 database.

This map is compiled using Environmental Systems Research Institute, Inc. (ESRI) ARC/INFO software. Political boundaries and cartographic representations on this map were taken, with permission, from ESRI's
ArcWorld 1:3M digital coverages, have no political significance, and are displayed as general reference only.
