A 2-year industry-sponsored World Map Project to add other global mineral deposit databases and enhance the geology subsequently was organized by R.V. Kirkham. This project resulted in the production of databases and distribution maps for porphyry and epithermal deposits (Kirkham and Dunne, 2000) and nickel deposits (Eckstrand and Good, 2000) and a database for volcanogenic massive sulfide (VMS) and sedimentary-exhalative deposits (Jenkins and Lydon, 2002). The geological dataset was revised to incorporate information such as better age ranges and magmatic composition to complement magma-related deposit databases. Enhancements to the data and revisions to many areas from new sources still are incomplete but are sufficient to provide thematic backdrops for the release of hardcopy maps showing the distribution of nickel deposits (Eckstrand and G...

Further, it is generally believed that the scale of the geologic map is a critical consideration. Previously published research has demonstrated that the U.S. Geological Survey porphyry tracts identified for the United States, which are based on 1:500,000-scale
