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.
