The Use of Oxygen Isotopes in High-Temperature Geological Thermometry

摘要: Recent measurements on the oxygen isotopic fractionation between calcite and water isotope coexisting minerals permit estimation of factor as a function temperature for systems involving any pair phases: quartz, calcite, hematite, water. The use these calibration curves geological thermometry is illustrated several natural samples. composition in hydrothermal fluids also estimated from measured O18/O16 ratios minerals. mean value thus 6%0 greater than ocean
