Geothermometry

Chemical geothermometers are used to estimate reservoir temperatures for most of the systems. The geothermometers are based on temperature- dependent, water-rock reactions which control the chemical and isotopic composition of the thermal water. This method is applicable only to hot-water systems because the common chemical constituents of thermal water (SiO2, Na, K, Ca, Mg, Cl, HCO3, and CO3) are soluble in liquid water but lack significant solubility in steam.[1]
