Plate 1: The Far East: This digitally compiled map is part of a worldwide series of maps on CD-ROM released by the U.S. Geological Survey‘s World Energy Project. 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. This map covers the northern portion of the Asia Pacific Region (Region 3) and includes the People‘s Republic of China, Japan, North and South Korea and Mongolia, and parts of Cambodia, Laos, Thailand and Vietnam. Two additional maps of the Asia Pacific Region cover Southeast Asia (Plate 2) and Australia and New Zealand (Plate 3) both to the south. The region is divided into geologic provinces. Each province has a set of geologic characteristics that distinguish it from surrounding provinces. These characteristics may include the predominant lithologies, the age of the strata, and the structural style. Some provinces include multiple genetically-related basins. Klett and others (1997) list all by the 2000 meter bathymetric contour. Each province is assigned a unique number. Because geological trends are independent of political boundaries, some provinces overlap two regions and two or more countries. Those provinces that lie entirely within the Asia Pacific Region begin with the number 3. Those provinces that lie partly within another region may start with a 1, for the Former Soviet Union, or an 8 for South Asia. For the sake of clarity province names are not included on this plate. Details of the data sources and map compilation are given in the metadata file on CD-ROM. The geologic outcrops on this map are based primarily on the Geologic Map of South and East Asia by Ghose and others (1990), used with permission. Some stratigraphic units are combined to simplify the map and to ensure consistency across the region. All rocks are colored by age. Sedimentary and metamorphic rocks are not differentiated, whereas igneous rocks and their types are indicated by patterns superimposed on the appropriate age color. The centerpoint locations of oil and gas fields are plotted based on the locations in the Petroconsultants database (1996) and are used with permission. This map is compiled using Environmental Systems Research Institute, Inc. (ESRI) ARC/INFO software. Political boundaries and cartographic representations on this map are taken, with permission, from ESRI (1992), they have no political significance and are displayed as general reference only.
