In a typical application, the average accumulation rate over a period of - years is obtained. From the accumulation rate, the age of sediment from a particular depth in the sediment column can be estimated. If one assumes that the accumulation rate has remained constant in the upper, more recent sediments, then the age of the sediments can be calculated for any depth in the core.
The Constant Rate of Supply CRS Model In a core that is long enough to have reached background Po activities, and that has experienced a constant input of Pb, it is possible to calculate the age at the bottom of any core section. A series of these age calculations can be used to develop a graph of age vs. Depending on the core, calculated ages greater than years should be treated with caution because counting errors and small variations in the background Po can cause large changes in the age estimates.
