TitleGeneralized Geology of the World: Major Fault Zones
AbstractThis theme depicts the generalized traces of major fault zones of the world, classified where possible into five displacement categories, and further classified into age ranges for each displacement if the information was readily available. The theme was derived from a more complex geospatial arc data set associated with a database that can store more than one displacement class and age range for each fault (all major fault zones have complex displacement histories). Default record sets are tagged for quick plots, and these were subjected to a sequential series of age and fault type queries. The geospatial data set was copied and simple attribute fields were attached and classified using the query results. The attribute fields are age at the eon level, age range at the era level, displacement type, combined age range and displacement type, and name. Many of the fault zones are still unclassified pending availability of source information.

The downloadable data summary has been extracted from a database compiled for the World Minerals Geoscience Database Project (1998-2003). Data sources for the fault zones are mainly 1-10 million scale maps and synthesis literature. The traces presented here are generalized and acknowledged to be inaccurate. They are simply presented for global scale visualization. Many source maps do not commit to the depiction of displacement classes because multiple histories and variations in interpretation may make such classification controversial.

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.
