TitleGeneralized Geology of the World: Age and Rock Type Domains
AbstractThis data set is a choropleth or patchwork map depicting generalized bedrock domains for era-level age ranges and predominant rock types. This theme was derived by sequentially querying the Generalized Geology of the World (GGW) rock unit database that houses age and rock type information in the detail reflective of the small scale (approximately1:5 million scale) data source map legends. Simplified attributes were attached to a copy of the GGW vector data and classified based on the query results, and boundaries for adjacent source domains that were classified to identical values were removed. The resulting spatially simplified data set includes four descriptive attributes: eon range (very general age), era range (age), predominant rock type(s), and combined era range and predominant rock type(s).

The level of spatial generalization is geared to global visualization on a wall map or over the web. This data set is spatially inaccurate. The accuracy of some of the original map data sources may be poor, and therefore intricate detail from relatively accurate sources was deliberately generalized for the sake of consistency. The attributes extracted from the full GGW dataset rely on the legends of source maps and accessibilty of appropriate details in literature sources.

TitleWorld Mineral Deposits
AbstractMineral deposits are natural accumulations of one or more useful minerals that may provide society with metallic or non-metallic raw materials. The Geological Survey of Canada has been compiling databases for major metallic mineral deposits on Canada-wide and world-wide scale over a three decade period. The most recent compilation was enabled by industry-sponsored World Map and World Minerals Geoscience Database Projects. Global databases for seven important metallic deposit types: lode gold, porphyry-related, nickel-platinum group-chromite, sedimentary exhalative lead-zinc, Mississippi Valley-type zinc-lead, iron oxide-copper-gold (IOCG), and sediment-hosted copper deposits are now available On-Line. Five easy-to-use thematic world geology datasets provide generalized geological context for the global databases.
