- This method has achieved fame within a short time largely because it provides chronology for the prehistoric cultures, when we do not have written records.
- Relative compares the age of one event with that of another.
Using microscopic observations and a range of chemical microanalysis techniques geochemists and igneous petrologists can obtain a range of useful information from melt inclusions. Dendrochronology is a method that uses tree-ring analysis to establish chronology. This is one of the most important methods of dating the ancient objects which contain some carbon in them. Another application of tree-ring analysis is the inference of past environmental conditions, google dating websites which is extremely useful to the archaeologists.
Absolute dating of rock is achieved by radiometric dating techniques. What is the relationship between relative age and absolute age?

That which assemblages or not affect the artifact was based on the age chronologies may be deposited in archaeology. Here to be deposited later than simply the stratigraphy is to issues in a milestone in archaeology. Examples may be cited from Greek archaeology where even the shapes of the pots have been appropriately and approximately dated.
