TitleGeneralized Geology of the World: Felsic and/or Intermediate Magmatic Domains Subdivided by Age
AbstractThis theme depicts the generalized global distribution of felsic and/or intermediate intrusive and volcanic rocks, subdivided by age range at the era level, against a backdrop of unclassified eon-level age domains (Precambrian and Phanerozoic). Magmas of this composition may originate at deep to shallow crustal levels, during rifting, mature stages of island arc volcanism, and by partial melting in response to rise of metamorphic temperature in the earth's crust.
This theme was derived by sequentially querying the Generalized Geology of the World (GGW) rock unit database housing 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) for classified rock types, classified felsic and/or intermediate rock type or the term 'unclassified', and combined era range and classified rock type or a combination of eon and the term 'unclassified rocks'. The level of spatial generalization is geared for global visualization. Therefore, this data set is geospatially inaccurate.

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.
