    Geochemistry of hydrothermal gold deposits: A review

    01-07-2011· Although ore-forming fluids derived from magma are common, hydrothermal systems without distinct affinities to magmatic activity can also result in the formation of large hydrothermal ore deposits (e.g., Au, Ag, Pd, Zn, Sb, Hg, etc.). A significant portion of the world’s natural gold endowment comes from hydrothermal ore deposits (Frimmel, 2008).
