This report surveys Tethyan gold metallogeny by reviewing the principal deposits of the Caraïbes, Alps—Himalaya, and southeastern Asia segments. The objective was not to draw up an exhaustive inventory of the gold deposits during the long-lived (≈250 million years) evolution of the Tethys; only those in which gold is, or has been, industrially extracted have been considered. In these cases, the tonnage is usually greater than 5 tons, inclusive of estimated reserves when concentration still is being mined. The resulting inventory is composed of about 150 deposits belonging to the four main Tethyan segments and represents (reserves + input) about 15% (e.g., ≈13,000 tons) of world production (Bache, 1982).
