|Thermal:||High mercury vapor concentration in soils can be indicative of active hydrothermal activity; Isotopic ratios can be used to characterize and locate subsurface thermal anomalies; Constrain the minimum temperature of fluid inclusion formation; certain elements exhibit high spatial correlation with high-temperature geothermal systems; Thermal conductivity can be measured from core samples|
Analysis and interpretation of isotopic data in rock and fluid samples are critical techniques in geothermal exploration and resource evaluation. There are many different isotopes, but they all generally fall into two categories; radioactive or stable. Radioactive isotopes have known decay rates and half-lives, which are very useful for dating particular fluids or materials. Stable isotopes do not decay and are used to measure the ratios of the heavy isotope vs light isotope to reveal general conditions that would lead to enrichment of a particular isotope over another. There are many applications of isotope geochemistry, some which have been utilized for geothermal exploration. The uses of isotopic analysis include investigation of the thermal history of a reservoir, determination of the degree of water-rock interaction that has occurred in a system, and dating hydrothermal alteration minerals, to name a few.
