Abstract: The formation of most metallic resources involves the focussed flow of very large (km3) fluid volumes. Different types of fluids, sea water, metamorphic fluids, meteoric fluids, with or without biomolecules, may be specific for certain metals or suites of metals. Whenever large fluid volumes are involved in a geologic process there is a potential for local metal enrichment. During weathering processes, short-term leaching produces fertile soils, long-term leaching produces laterite.
