This describes a metallogenic map of the world, compiled at 1:22, 000, 000, which relates geologic structural elements with principal mineralization processes and recognizable regularities in the distribution of metallic ores. The structural elements delineated include two types of shield areas and five types of mobile folded zones, the latter distinguished on the basis of age of folding. The types of mineral deposits recognized are: 1) magmatic, 2) pegmatitic, 3) skarn, 4) hydrothermal, 5) sedimentary, 6) deposits resulting from metamorphism, 7) weathering, and 8) diamond deposits of all kinds. The specific ore deposits are classified as either 1) very large deposits of world importance, or 2) other industrial deposits. Shield areas are typically associated with such ore formations as metamorphic deposits of Fe, Mn, Au, U, sulfide deposits of Cu-Ni, and rare-metal pegmatites. Within mobile folded zones, mineralization usually manifests four successive stages, each characterized by a specific metallogeny and isolated in space. M. Russell
