As igneous rocks do not contain fossils, absolute dating can only be used to date the strata above or below the fossil bearing strata.Relative dating is based on super imposition and fossils.In relative dating, fossils are dated according to the depth at which they were buried.The deeper strata is presumed to be older than strata above.The strata with the simpler fossils is presumed to older than strata with more complex fossils regardless of which is above the other.
