Abstract(unpublished)
The 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 stockwork and vein deposits directly connected to the intrusions (porphyry deposits), porphyry-associated replacement deposits in a predominantly calc-silicate, formerly carbonate-rich sedimentary rock hosts (skarn deposits), and large precious metal (+/- base metal) deposits that are removed from but associated with 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 byproduct metals include tungsten, platinum, palladium, and selenium. This database was converted for update into the World Minerals Geoscience Database format.
