Oxygen isotopic compositions ([delta][sup.18][O.sub.carb]) of pedogenic carbonates reflect both the temperature of precipitation and [delta][sup.18]O composition of the fluid that the carbonates crystallized from (e.g., [14]), and as a result, have been used to reconstruct both of those variables by assuming the other, through an independent constraint on one variable or other, and more recently, through the use of "clumped isotope" measurements, which produce temperatures that are independent of the starting fluid isotopic composition.
