This uses radioactive minerals that occur in rocks and fossils almost like a geological clock.It’s often much easier to date volcanic rocks than the fossils themselves or the sedimentary rocks they are found in.Use of relative-dating analyses to correlate between dissimilar geomorphic systems requires caution but use of a broad range of techniques and absolute-age calibration may make correlation possible.For those researchers working in the field of human history, the chronology of events remains a major element of reflection.Other relative-dating techniques that are commonly employed, however, suggest distinct differences between the terrace and moraine sequences.These differences probably reflect the difference in relief, such that slow erosion of the moraine crests may have retarded soil development relative to the flat terrace surfaces and altered surface-weathering processes. There are two main methods determining a fossils age, relative dating and absolute dating.

But, how can we determine how old a rock formation is, if it hasn’t previously been dated?

Using relative dating the fossil is compared to something for which an age is already known.
