Plate 3: Australia and New Zealand: 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 is divided into eight regions based on political boundaries, and corresponding approximately to the economic regions of the world as defined by be U.S. Department of State. This map covers the southern part of the Asia Pacific Region (Region 3) and includes Australia, Fiji, New Caledonia, New Zealand, Tonga and Vanuatu. Two additional maps of the Asia Pacific Region cover the Far East (Plate 1) and Southeast Asia (Plate 2) both to the north. 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 contain multiple genetically-related basins. Klett and others, (1997) list all the provinces identified by the World Energy Project and rank them by known petroleum volumes. Offshore province boundaries are defined by the 2000 meter contour. Each province is assigned a unique number that begins with region number (3). Details of the map sources and compilation are given in the metadata file on the CD-ROM. The geologic outcrops on this map are based primarily on the Geological Map of the World: Australia and Oceania by the Bureau of Mineral Resources (now Australian Geological Survey Organisation)(1965 and 1967) and the New Zealand Geological Survey (Institute of Geological and Nuclear Sciences Limited)(c)(1971). 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) with their 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 a general reference only.
