Dataset: World Distribution of Porphyry, Porphyry-Related Skarn, and Bulk-mineable Epithermal Deposits

TitleWorld Distribution of Porphyry, Porphyry-Related Skarn, and Bulk-mineable Epithermal Deposits
AbstractThe global distribution of a broad class of large, low- to medium-grade mineral deposits in which primary ore minerals are mainly structurally controlled, and which are spatially and genetically related to felsic to intermediate porphyritic intrusions, is represented in this data set. Variations of this class include large mineralized stockwork and veins directly connected to the intrusions (porphyry), replacement deposits in a predominantly calc-silicate (formerly carbonate-rich sedimentary rock) host (porphyry-associated skarn), and large precious metal (+/- base metal) deposits that are distal but related to porphyry deposits (epithermal deposits). Porphyry and porphyry-associated deposits are the world's most important source of copper, molybdenum, and rhenium, and are major sources of gold, silver, and tin. Other by-product metals include tungsten, indium, platinum, palladium, and selenium.

The downloadable data summary is periodically extracted from a database compiled between 1982 and 2004, in part for the World Map Project (1995-1997) and updated 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.
