Water and gas sampling of natural discharges are the most common type of geochemical surveys for geothermal exploration. However, these natural discharges are generally scarce at geothermal exploration areas where the extent of the field is not known.
Therefore, soil chemical (Hg, As, NH3 and B) and soil-gas surveys (222Rn, CO2, He, H2, CH4, etc.) are becoming a useful geochemical tool to identify permeable areas and potential upflow or boiling zones.
These surveys can also help to delineate the margins of a geothermal system, and therefore often complement geophysical surveys particularly where the interpretation of geophysical data showssome difficulties.
