Fluorine dating archaeology
– Objects found deeper in the ground are older (law of superposition) – Type dating (Seriation): types of artifacts are arranged chronologically according to style.Type dating can be done with modern cars to stone tools.The majority of chronometric dating methods are radiometric, which means they involve measuring the radioactive decay of a certain chemical isotope.They are called chronometric because they allow one to make a very accurate scientific estimate of the date of an object as expressed in years.
This works better in temperate areas that have more distinct growing seasons (and this rings) and relatively long-lived tree species to provide a baseline.
These strata are often most visible in canyons or gorges which are good sites to find and identify fossils.
Understanding the geologic history of an area and the different strata is important to interpreting and understanding archaeological findings.
It all depends on what the object is, where the archaeologist is located (what resources he/she has access to), and how old the artifact appears to be. Not every artifact is eligible for all dating methods; for example, an artifact must be made from a carbon-based material to use radiocarbon dating (stone, for example doesn’t have carbon).
A stone artifact can be dated based on the way it looks and/or the way it was made.
