Dataset: World Distribution of Sedimentary Exhalative (Sedex) Pb-Zn Deposits

Last update2013-10-03T08:21:05Z
TitleWorld Distribution of Sedimentary Exhalative (Sedex) Pb-Zn Deposits
AbstractThe spatial distribution and most significant geological attributes of the world's largest sedimentary exhalative (Sedex) lead-zinc metallic mineral deposits and mineral districts are depicted in this data set. These deposits are hosted by marine sedimentary rocks, such as shale, greywacke, and carbonate, and are thought to have originated because of the submarine venting of hydrothermal fluid rich in zinc and lead.

The downloadable data summary has been extracted from a database prepared for the World Minerals Geoscience Database Project (1998-2003). The full database can be viewed and queried over the Internet.

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.
