Dating refers to the archaeological tool to date artefacts and sites, and to properly construct history. Relative techniques can determine the sequence of events but not the precise date of an event, making these methods unreliable. This method includes carbon dating and thermoluminescence. The first method was based on radioactive elements whose property of decay occurs at a constant rate, known as the half-life of the isotope. Today, many different radioactive elements have been used, but the most famous absolute dating method is radiocarbon dating, which uses the isotope 14 C. This isotope, which can be found in organic materials and can be used only to date organic materials, has been incorrectly used by many to make dating assumptions for non-organic material such as stone buildings.

Archaeological Dating: Stratigraphy and Seriation
This task of interpretation has five main aspects. The first concern is the accurate and exact description of all the artifacts concerned. Classification and description are essential to all archaeological work, and, as in botany and zoology , the first requirement is a good and objective taxonomy. Second, there is a need for interpretive analysis of the material from which artifacts were made. This is something that the archaeologist himself is rarely equipped to do; he has to rely on colleagues specializing in geology , petrology analysis of rocks , and metallurgy. In the early s, H.
Relative dating considers how old artifacts and sites are, in comparison to other artifacts and sites. Stratigraphy and style are both used for relative dating. Although relative dating can tell us what is older or younger, it doesn't tell us exactly how old something is. For many years archaeologists had no way of determining the real age of sites, and had no good idea of the time depth involved. Stratigraphy The main principle behind stratigraphy is that of superposition.
Time is relative. Different cultures around the world record time in different fashions. According to the Gregorian calendar, it is the year AD. But according to the Hebrew calendar it is Chances are, right now, you have a Gregorian calendar stuck to your wall.
