Radiometric dating and certain other approaches are used to provide absolute chronologies in terms of years before the present.The two approaches are often complementary, as when a sequence of occurrences in one context can be correlated with an absolute chronlogy elsewhere.Any feature, including colour variations, textures, fossil content, mineralogy, or any unusual combinations of these can be used.
Dating, in geology, determining a chronology or calendar of events in the history of Earth, using to a large degree the evidence of organic evolution in the sedimentary rocks accumulated through geologic time in marine and continental environments.

However, little is understood about the environmental roles, transport and distribution of black carbon.

It should be emphasized that linking sites together is essential if the nature of an ancient society is to be understood, as the information at a single location may be relatively insignificant by itself.
