About the CD-ROM ================ Publication Information ----------------------- Recommended Citation: Chorlton, L. B. (Compiler), 2007: Generalized Geology of the World: Bedrock Domains and Major Faults in GIS Format; Geological Survey of Canada, Open File 5529, 1 CD-ROM. © Her Majesty the Queen in Right of Canada 2007 NOTE: Open files are products that have not gone through the GSC formal publication process. This release of the Generalized Geology of the World GIS data set supercedes the first published version of the Generalized Geology of the World, GSC Open File 2915 (1995). Geospatial features for bedrock domains were largely replaced, and some faults were revised, and the database was enhanced during the World Map Project (1995-1997), coordinated by R. V. Kirkham, and the World Minerals Geoscience Database Project (1998-2003), coordinated by W. Dave Sinclair. Windows® 95/98/2000 is required to access the data on this CD-ROM. The free viewer, ArcReader™9.1 is included in the apps directory on the CD-ROM, and must be executed to install the application on a local computer. ArcMap™9.1, ArcView™3.1 or higher or MapInfo™6.0 or higher can be used to view and create custom maps with the geospatial data sets. Ms-Access™2000 or higher can be used to explore the full bedrock unit and fault databases. The data includes ESRI shape files of GIS features for use in ArcView™3.1 or greater, MapInfo TAB files for use with MapInfo 6.0 or greater. These custom data sets were extracted from the main workstation ArcInfo™ coverages and geological attribute database as five themes: (1) era-level age and general bedrock category; (2) Precambrian age and general bedrock category; (3) mafic and/or ultramafic volcanic and intrusive domains subdivided by age; (4) felsic and/or intermediate volcanic and intrusive domains subdivided by age; and (5) faults subdivided by main age and fault type. The full vector layers (all polygons and arcs) are also included on the CD-ROM so that advanced users can add to the data or create other themes using the full attribute databases in dBase and MS-Access™ format. Once ArcReader is installed locally, maps can be created quickly by clicking on the *.pmf files in the /data/ArcReader directory. The same data can also be loaded quickly if ArcMap is available by clicking on ArcMap™9.1 mxd files in the /data/ArcMap9 directory. After the ArcView31 folder is extracted from ArcView31.zip, the ESRI shape files and legend can be loaded quickly in ArcView™3.1 by activating the apr files included in each thematic folder. Avl files for each theme are located in the theme's folder. After the MapInfo6 folder is extracted from MapInfo6.zip, the MapInfo™ workspaces can be loaded by clicking on the .WOR files located in each of the MapInfo™ thematic folders. Coastlines and shorelines (base map) integrated with geological boundaries of the rock unit geology coverage were taken from the 25 million World Data Bank II public domain data set. These data sets are highly generalized. The contacts are defined with as few vertices as possible in order to emphasize the high level of generalization. The accuracy of the source data, mainly paper maps, is highly variable as is their level of generalization. Source maps were themselves generalized compilations which varied from 1:1,000,000 to 1:10,000,000 paper scale, and were predominantly 1:5,000,000 paper scale. Therefore, these data were prepared for viewing on a global to continental scale only. Please refer to the README.TXT files in each directory for information specific to the directory contents.

Age terms: --------- The lookup table for geological age terms was derived mainly from: Harland, W. B., Armstrong, R. L., Cox, A. V., Craig, L. E., Smith, A. G., and Smith, D. G., 1990: A geologic time scale, 1989; Cambridge University Press, 263 pages. This source was utilized because it documents most of the age terms that used in the data sources for the bedrock geology, as well as world mineral deposits compiled during the World Map and World Mineral Geoscience database Projects. A table reflecting the new IUGS calibrations will be adopted when the list of age terms is more complete.
