If the concentration of substances at different depths is compared with the corresponding ages, the accumulation rates of these substances at different times may be determined from the sediment accumulation rate.

Thus, it will be possible not only to describe the sediment age, but also to give a picture of the dominant mixture of plankton alga at the same time.
Sediment studies may also be supplemented with determinations of e.g. Method Decay of uranium in the earth's crust releases the gas radon.
About 20 different kinds of amino acids are found in proteins.
Each amino acid has two chemical groups, an amino group and a carboxyl group, which can form chemical bonds with other amino acids.
In addition to the mentioned rates, the dating may also give a picture of the stability of the sediments and thus tell whether the chronology of the layers is intact or whether the activity of the benthic fauna has changed the chronology by bioturbation.
