| Abstract |
Applications of geothermometry constitute one of the major tools for the exploration and development of geothermal resources. Geothermometry is simply the estimation of the reservoir (subsurface) temperatures using the chemical and isotopic composition of surface discharges from wells and/or natural springs/fumaroles. Geotheromometers are classified into two groups: Chemical Geothermometers and Isotopic Geothermometers. The former utilizes the chemical composition (essentially the silica and major cation contents of water discharges, and the gas concentrations or relative abundances of gaseous components in steam discharges), whereas the latter is based on isotope exchange reactions between various phases (water, gas, mineral) in geothermal systems. This course is designed to focus on the chemical geothermometers as applied to water discharge. The course consists of two major parts: the first part summarizes the basic principles and types of chemical geothermometers along with the the relevant equations applied; the second part is devoted to examples/problems concerned with the application of chemical geothermometers to geothermal systems. |
