Paleo-thermometer

In 1947 Harold Urey, the 1934 Nobel Laureate, recognized that the temperature dependence of the isotope exchange equilibrium between water and calcite (the principal mineral in marine limestones) could be employed as a paleo-thermometer. At 298.15 K the fractionation factor for calcite-water is 1.0286,... [Pg.293]

The information contained in the glacier archive is manifold. The composition of the water molecules (stable isotope ratio of hydrogen H/ H and oxygen 0/ 0) is often used as a paleo thermometer, for example [4]. In addition, the ice contains... [Pg.143]
