This report on nonfuel mineral deposits and resources of the Asia and the Pacific region is one of a series of geologic regional reports produced by the U.S. Geological Survey to provide up to date summary information of known and undiscovered mineral resources around the globe (Cunningham and others, 2005; Nokleberg and others, 2005; Zientek and others, 2005). These geologic regional reports are designed to be informative with respect to the location and endowment of mineral resources for each region. Boundaries of these regions are those of the USGS Minerals Yearbooks, which monitor production and economic factors affecting the mineral industries of the regions. Additional and historic information related to mineral production statistics also can be found in the Yearbooks. The area described within each of the regional reports is shown on Figure 1 and the Yearbooks are available on line at http://minerals.usgs.gov/minerals/pubs/myb.html. <...>
