It is the sequencing of events or materials relative to another but without linkage to ages in years bp before present or calendar years. A relative date is a date which can be said to be earlier than, later than, or contemporary with an event but which unlike an absolute date cannot be measured in calendar years. When archaeologists say that event A occurred before or after event B, they have a relative date for A. Before the advent of chronometric dating techniques, all dating was relative except where links with historical events could be proved. Some of these techniques, mainly stratigraphy and seriation, are still useful where chronometric dates cannot be obtained.

A method developed by Sir Flinders Petrie for Egyptian predynastic cemeteries for dating a group Absolute dating techniques listed. Seriation (archaeology) similar objects according to their archaeological sequence. By studying the typology the changing forms of Absilute artifacts, they may be set into sequence. Petrie used it to arrange undated graves into a hypothetical relative chronological order according to the typology and association of Seriatio artifacts found in them Absolute dating techniques listed.
Seriation (archaeology) on a stylistic seriation of Egyptian pre-dynastic tomb pottery. In recent (archafology), a few of these methods (archaoelogy) come under close scrutiny as techniquues strive to develop the most accurate dating techniques possible. They do not provide an age in years. Before the advent of absolute dating methods, nearly all dating was relative. The main relative dating method is stratigraphy. Absolute dating is the term used to describe any dating technique that tells how old a specimen is in years. These are generally analytical methods, and are carried out in a laboratory. Absolute dates must agree with dates from other relative methods in order to be valid.
As previously mentioned, radioactive decay refers to the process in which a radioactive form of an element is converted into a nonradioactive product at a regular rate. Radioactive decay dating is not a single method of absolute dating but instead a group of related methods for absolute dating of samples. Additional Topics Dating Techniques - Seriation Seriation is the ordering of objects according to their age. If archaeologists know how pottery styles, glazes, and techniques have changed over time they can date sites based on the ratio of different kinds of pottery. This also works with stone tools which are found abundantly at different sites and across long periods of time.
Principle of stratigraphy[ edit ] Stratigraphic dating is based on the principle of depositional superposition of layers of sediments called strata. The earliest-known hominids in East Africa are often found in very specific stratigraphic contexts that have implications for their relative dating.
These strata dtaing often most visible in canyons or gorges which are good sites to find and identify fossils. Understanding the geologic history of an area and Seriaation different strata is important to interpreting and understanding archaeological findings. Chronometric dating methods[ edit ] 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.
