Giant porphyry-related camps of the world: a database (incl. references)/ Гигантские области, связанные с месторождениями порфирового типа в мире: база данных (в т.ч. библиография)

The worksheet called Deposits contains descriptive information, and the original, compiled data on metal endowment of the deposits. The deposits worksheet can be viewed by clicking on the tab in the lower left-hand corner of this window called "deposits"

Porphyry-related metal deposits are large-tonnage, generally low-grade, hydrothermal deposits related to igneous intrusions emplaced at high crustal levels. Mineralization may be confined to pluton-hosted disseminations, stockworks, vein sets, and breccias and (or) occur in skarns, replacements, veins, and disseminated deposits peripheral to the inferred source pluton. Coeval epithermal precious metal-dominated deposits may occur above, or be telescoped onto, porphyry systems. This spectrum of deposit types includes many of the world's largest accumulations of Cu, Mo, Au, Ag, Sn, and W. As such the deposits represent critical economic resources and important exploration targets (Gilmour et al., 1995; Kirkham and Sinclair, 1996; Singer, 1995).
To prospect efficiently for undiscovered mineral deposits, or to speculate about future metal supply, it is useful to define the size, distribution, and geologic characteristics of known deposits. It is to that end that we have compiled this database, the release of which is part of a larger effort to characterize the world's largest and most important porphyry-related deposits. We hope that this compilation can be of aid to researchers, explorationists, and students alike. We also recognize that any compilation effort is, by its very nature, incomplete, as well as out-of-date as soon as it is released. Thus, we welcome any corrections or updates to the data presented here and request that you direct any communications to Felix Mutschler at 509-359-2854 or Steve Ludington at 650-329-5371.
