Fluid inclusions (FI) represent the best tool available for determining temperatures and pressures of ore-forming processes and provide the only direct method for determining compositions of ore-forming fluids. More than 58 000 individual fluid inclusion measurements from approximately 680 hydrothermal ore deposits have been compiled to describe the fluid environments of ore formation in Mississippi Valley-type (MVT) Pb–Zn deposits; orogenic gold deposits; epithermal precious and base metal deposits; porphyry copper, molybdenum, and tin–tungsten deposits; volcanogenic massive sulfide (VMS) deposits; skarn deposits; and Carlin-type gold deposits. For each deposit type for which appropriate data are available, homogenization temperatures, fluid compositions, fluid sources inferred from chemical and isotopic compositions of fluids extracted from fluid inclusions, and pressures (depths) of mineralization estimated from fluid inclusion data are summarized.
