Map service showing geology and geologic contacts of the Arabian Peninsula

This digital map compilation, which includes geology, geologic provinces, and oil and gas fields of the Arabian Peninsula, is part of a map series of the world produced by the U.S. Geological Survey World Energy Project. The goal of the project is to produce a worldwide assessment of the undiscovered, technically recoverable oil and gas resources and report these results by the year 2000. To assess the world's petroleum, a sequence of steps is being undertaken proceeding from defining geologic provinces of the world at a comparable scale, allocating oil and gas fields to these provinces, defining petroleum systems within these provinces, and ultimately assessing the undiscovered petroleum potential of selected provinces of the world. A more in-depth discussion of the geologic provinces and their relative ranking in terms of total known petroleum volume is given in USGS Open File Report 97-463 (see Klett and others, 1997). For the World Energy assessment, the world was divided into eight energy regions which correspond approximately with the economic regions of the world as defined by the U.S. Department of State. The Arabian Peninsula portion of Region 2 is represented on this CD-ROM (see insert Reference Map on geologic map). The geology map of the Arabian Peninsula was compiled and synthesized primarily from the U.S. Geological Survey-- Arabian American Oil Company, 1963, 1:2,000,000 scale Geologic map of the Arabian Peninsula. Additional geology in the northern portion of this map for parts of Iraq, Jordan, Syria, Israel, and Lebanon was derived with permission from the 1:5,000,000 scale, 1971 version of the Geologic Map of Europe, Eastern sheet, published by UNESCO (see Selected References no.4). Specific details of the data sources are given in the metadata file on this CD-ROM. Map units were combined to simplify the map when projected at a larger scale and to maintain consistency with other region maps. Precambrian rocks are undivided and consist of sedimentary, metamorphic, and igneous types. The boundary for Region 2 (Middle East/North Africa) is shown as an inset on the map. Oil and gas field markers represent field centerpoints published with permission from Petroconsultants International Data Corp., 1996 database. Each region was divided into geologic provinces. Geologic province boundaries for the Arabian Peninsula were delineated onshore using data from the U.S. Geological Survey--Arabian American Oil Company, and UNESCO geologic maps (see Selected References), and other tectonic and geographical data from the publications listed in the Selected References section. Offshore geologic province boundaries are defined by the 2000 meter bathymetric contour from the U.S. Geologic Survey--Arabian American Oil Company 1963 geologic map (see Selected References). Provinces may contain one dominant element or a number of contiguous elements or basins that are genetically related. Each geologic province was assigned a unique number; the first digit is the region number. An attempt was made to number the provinces in geographical order. In the Arabian Peninsula the numbering starts in the southernmost portion of the peninsula, generally increasing to the east and north. This map was compiled and displayed using Environmental Systems Research Institute, Inc. (ESRI) Arc/Info, ARCVIEW, and ArcPlot softwares. Political boundaries and their cartographic representation on this map were taken with permission from ESRI's ArcWorld 1:3,000,000 Arc/Info digital coverage, have no political significance, and are displayed as general reference only.
