Two broad categories of dating or chronometric techniques that archaeologists use are called relative and absolute dating.

Stratigraphy is the oldest of the relative dating methods that archaeologists use to date things.

Bones are primarily composed of the mineral calcium hydroxy apatite.

The archaeologists record and analyze the changes in types and styles of human-made items from different levels according to the principle explained below.Absolute dating entails laboratory analysis of rock samples that will take a longer time.further, the dating results will still have to be cross-checked with mapping data.Cross-dating of sites, comparing geologic strata at one site with another location and extrapolating the relative ages in that manner, is still an important dating strategy used today, primarily when sites are far too old for absolute dates to have much meaning.The scholar most associated with the rules of stratigraphy (or law of superposition) is probably the geologist Charles Lyell.
