Some fifty years ago, a classic theoretical paper (Urey 1947) proposed that the oxygen isotope ratio ( 0/ 0) in various minerals depends on two variables the local environmental temperature and the oxygen isotopic ratio in the environmental water. The proposal was verified experimentally in carbonates (Epstein et al. 1951, 1953 McCrea 1950) where the oxygen isotope ratio is dependent on the temperature of formation and the ratio in...
