This map was created as part of a worldwide series of
geologic maps for the U.S. Geological Survey's World Energy Project.
These products are available on CD-ROM and the Internet. The
goal of the project is to assess the undiscovered, technically
recoverable oil and gas resources of the world. Two previously
published digital geologic data sets (U.S. and Caribbean) were
clipped to the map extent, while the dataset for Mexico was digitized
for this project. Original attributes for all data layers were
maintained, and in some cases, graphically merged with common
symbology for presentation purposes.
The world has been divided into geologic provinces that are used
for allocation and prioritization of oil and gas assessments.
For the World Energy Project, a subset of those provinces is
shown on this 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, and/or
The World Geographic Coordinate System of 1984 is used for data
storage, and the data are presented in a Lambert Conformal Conic
Projection on the OFR 97-470-L map product. Other details about
the map compilation and data sources are provided in metadata
documents in the data section
on this CD-ROM.
