10°0'0"N 15°0'0"N 20°0'0"N 25°0'0"N Introduction This map was created as part of a worldwide series of geologic maps for the U.S. Geological Survey's World Energy Project, available on CD-ROM and through the Internet. The goal of the project is to assess the undiscovered, technically recoverable oil and gas resources of the world. For data management purposes, the world was divided into eight energy regions based on political boundaries and corresponding approximately to the economic regions of the world as defined by the U.S. Department of State. Region Six encompasses the Caribbean area, Central America, and South America. Geologic maps were compiled for South America on Open-File Report 97-470-D. Countries listed below are shown whole or in part within the map extent: Anguilla, Antigua and Barbuda, Aruba Bahamas, Barbados, Belize, British Virgin Islands, Cayman Islands, Colombia, Costa Rica, Cuba, Dominica, Dominican Republic, El Salvador, Grenada, Guadeloupe, Guatemala, Guyana, Haiti, Honduras, Jamaica, Martinique, Mexico, Montserrat, Netherlands Antilles, Nicaragua, Panama, Puerto Rico, St. Kitts and Nevis, St. Lucia, St. Vincent and the Grenadines, Trinidad and Tobago, Turks and Caicos Islands, United States, Venezuela, and the Virgin Islands. An index map in the lower left-hand corner shows the study area in a world context. The world was previously divided into geologic provinces for the World Energy Project, of which a subset is shown on the map. Each province has a set of geologic characteristics that distinguish it from surrounding provinces. These characteristics may include dominant lithologies, the age of the strata, structure, or other geologic features. Each province is assigned a unique number and may fall within two or more countries or assessment regions. Additional information regarding the map compilation and data can be found on the CD-ROM for USGS Open-File Report 97-470-K entitled "Map Showing Geology, Oil and Gas Fields, and Geologic Provinces of the Caribbean Region." In addition, it is available online at: http://certmapper.cr.usgs.gov/pubs/servlet/PubBroker?issue=ofr97470k Various software packages were used to create this map including: Environmental Systems Research Institute, Inc. (ESRI) ArcGIS 8.3, ArcInfo software, Adobe Photoshop CS, Illustrator CS, and Acrobat 6.0.
