Electron microprobe analyses of skeletal carbonate structures in coralline algae and pelecypods show that the magnesian content of the calcite depends on skeletal growth rates. Growth rate is a function of certain variables, including water temperature, light, and physiological cycles. The Mg-content of calcareous sediment from specific organisms is not, therefore, mainly dependent on water temperature, as is generally believed, but also on the other factors affecting growth.
