Service Description: This digitally compiled map includes geology, oil and gas field centerpoints, geologic provinces, and major faults of Iran with some of these components extended into geographically adjacent areas. This digital compilation is an interim product of the U.S. Geological Survey's World Energy Project (WEP) and part of a series on CD-ROM. The goal of the WEP is to assess the undiscovered, technically recoverable oil and gas resources of the world and report the result of this assessment in 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. Each world energy region was then further divided into geologic provinces on the basis of natural geologic entities and may include a dominant geologic structural element or a number of contiguous elements. Some provinces contain multiple, genetically-related basins. Geologic province boundaries for Iran were delineated using data from different geologic maps, publications, and other tectonic and geographic data. Each province was assigned a unique number; the first digit is the region number. An attempt was made to number the provinces in geographical order or groups with numbering starting at the Arabian Shield (see Pollastro and others, 1998). The list of provinces sorted by number is shown to the right of the map. Centerpoints of oil and gas fields are shown and were plotted with permission from Petroconsultants International Data Corporation, 1996 worldwide oil and gas field database. Allocation of field data to geologic provinces provided a ranking of the provinces by total known petroleum volume (see Klett and others, 1997). The WEP further characterizes the geologic provinces by petroleum system and assessment units in order to assess the undiscovered petroleum volume. Specific details of map and data sources, and the procedure used in the compilation of this geologic map of Iran are given in the metadata file and described briefly in the text below. Stratigraphic subdivisions of Phanerozoic rocks were combined to simplify the geology and maintain consistency with other maps in this series. Precambrian rocks are undivided. This map was compiled using Environmental Systems Research Institute, Inc.(ESRI) ARC/INFO software. Political boundaries and cartographic representations are used, with permission, from ESRI's ArcWorld 1:3M digital coverages, have no political significance, and are displayed for general reference only.
