The carbon-isotopic composition of shell carbonate is shown to be in isotopic equilibrium with bicarbonate dissolved in the water. By measurement of both 13C and 18O in a series of brackish-water shells a mean growth temperature can be deduced.
贝壳碳酸盐的碳同位素组成被证明与溶解在水中的碳酸氢盐处于同位素平衡状态。通过测量一系列微咸水贝壳中的碳-13和氧-18,可以推断出平均生长温度。
