The field of stable isotope geochemistry began with the recognition that the oxygen isotope composition of ancient carbonates could be used as a paleothermometer (Urey 1947; Urey et al. 1951). As stated by Urey (1947), “Accurate determinations of the Ol8 content of carbonate rocks could be used to determine the temperature at which they were formed”. This concept was based on the temperature dependence for the oxygen isotope fractionation between calcite and water. Urey realized that if a mass spectrometer with sufficient precision could be built, a method of reproducibly extracting oxygen from...

二氧化硅-水和碳酸盐-水系统中的三重氧同位素

稳定同位素地球化学领域始于认识到古代碳酸盐的氧同位素组成可以用作古温度计（Urey，1947； Urey等，1951）。如Urey（1947）所述，“碳酸盐岩石中Ol8含量的准确测定可用于确定其形成温度”。这个概念基于方解石和水之间氧同位素分馏的温度依赖性。Urey意识到，如果可以制造出具有足够精度的质谱仪，那么可以从...
