Guild ABSTRACT base to extremely complex interpretations of how The Preliminary Metallogenic Map of North America, scale the ores fit into the geologic/tectonic evolution of 1:5,000,000, shows 4,215 ore deposits of the continent and adja the region in which they occur. The Preliminary cent islands by symbols on a background adapted from existing Metallogenic Map of North America is about geologic, tectonic, and metamorphic maps. The deposits (metal lic and some nonmetallic) are categorized by the commodities midway in this spectrum; it is considered a they contain, size, geologic environment, age, and mineralogic mineral-deposit map by some, rather than a true nature. A listing of deposits, keyed by numbers to the map, metallogenic map. This was a deliberate, conscious identifies the deposits by name and gives supplementary infor decision on the part of the compilers, who believe mation about them. that presentation of the facts should precede their interpretation; indeed, too much interpretation at INTRODUCTION this stage might preclude acceptance of the This circular is designed to be used in conjunc product by those who may have other theories as tion with and as a complement to
