This digitally compiled map includes petroleum geology, geologic provinces, and oil and gas fields of South Asia. The map is part of a worldwide series released by the U. S. Geological Survey World Energy Project. 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 was divided into eight energy regions corresponding approximately to the economic regions of the world as defined by the U.S. Department of State. South Asia (Region 8) is represented on this CD-ROM (see Reference Map), and includes Afghanistan, Bangladesh, Bhutan, India, Myanmar, Nepal, Pakistan, and Sri Lanka.

Each region was 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 South Asia were delineated using data from UNESCO geologic maps, and other tectonic and geographic data (see Selected References). Offshore province boundaries were defined by the 2000 meter bathymetric contour from the UNESCO geologic maps (see References). Each province was assigned a unique number; the first digit is the region number. An attempt was made to number the provinces in geographical groups; onshore, offshore, and combined on and offshore. In South Asia, the numbering starts in the west. Oil and gas field data from Petroconsultants International Corporation worldwide oil and gas field database were 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. For a more in-depth discussion of the geologic provinces and their relative ranking in terms of total known petroleum volume, see Klett and others, 1997.

This map for South Asia was compiled and synthesized primarily from the UNESCO, 1976 and 1990, geologic maps of South and East Asia, 1:10,000,000 and 1:5,000,000 scales respectively. Specific details of the data sources are given in the metadata file on this CD-ROM. Geologic units were combined to simplify the map and to maintain consistency with other maps of the series. Precambrian rocks are undivided. Paleozoic, Mesozoic, and Cenozoic rocks have been combined in many cases (see Explanation). Oil and gas field markers represent field centerpoints published with permission from Petroconsultants International Data Corp., 1996 database.

This map was compiled using Environmental Systems Research Institute, Inc. (ESRI) ARC/INFO and ArcPlot softwares.
