Archaeological Dating: Stratigraphy and Seriation
Absolute dating can be achieved through the use of historical records and through the analysis of biological and geological patterns resulting from annual climatic variations, such as tree rings dendrochronology and varve analysis. Since the physical sciences contributed a number of absolute dating techniques that have had a revolutionary effect on archaeology and geology. These techniques are based upon the measurement of radioactive processes radiocarbon; potassium-argon, uranium-lead, uranium-thorium, thorium-lead, etc. Other techniques are occasionally useful, for example, historical or iconographic references to datable astronomical events such as solar eclipses archaeoastronomy. When archaeologists have access to the historical records of civilizations that had calendars and counted and recorded the passage of years, the actual age of the archaeological material may be ascertained—provided there is some basis for correlating our modern calendar with the ancient calendar. With the decipherment of the Egyptian hieroglyphics, Egyptologists had access to such an absolute timescale, and the age, in calender years, of the Egyptian dynasties could be established. Furthermore, Egyptian trade wares were used as a basis for establishing the age of the relative chronologies developed for adjoining regions, such as Palestine and Greece.

Cross Dating Archaeology
The dating of remains is essential in archaeology, in order to place finds in correct relation to one another, and to understand what was present in the experience of any human being at a given time and place. Inscribed objects sometimes bear an explicit date, or preserve the name of a dated individual. In such cases, dating might seem easy. However, only a small number of objects are datable by inscriptions, and there are many specific problems with Egyptian chronology, so that even inscribed objects are rarely datable in absolute terms.
In the archaeology of part-literate societies, dating may be said to operate on two levels: the absolute exactness found in political history or ‘history event-by-event’, and the less precise or relative chronology, as found in social and economic history, where life can be seen to change with less precision over time.
The contrast might also be drawn between two ‘dimensions’, the historical, and the archaeological, corresponding roughly to the short-term and long-term history envisaged by Fernand Braudel.

Dating Techniques in Archaeological Science
Dating in archaeology is the process of assigning a chronological value to an event in the past. Philosophers differ on how an event is defined, but for cultural history, it can be taken as a change in some entity: the addition, subtraction, or transformation of parts. Events can be considered at two scales. At the scale of individual object, the event is either manufacture which, e.

Following the death of an organism, any exchange ceases and the carbon 14, which is radioactive and therefore unstable, slowly begins to disintegrate at a known rate half-life of years, ie, after this period only half of the and carbon 14 present at and time of death remains. A sample requires 10 to 20 grams of matter and usually and of charred organic material, mainly stratigraphy, but bones see zooarchaeology and shells can also be archaeology cross this technique.

The good dates are confirmed using at least two different methods, ideally involving multiple independent labs for each method to cross-check.

Dating techniques are procedures used by scientists to determine the age of rocks, fossils, or artifacts. Relative dating methods tell only if one sample is older or younger than another; absolute dating methods provide an approximate date in years. The latter have generally been available only since Many absolute dating techniques take advantage of radioactive decay , whereby a radioactive form of an element decays into a non-radioactive product at a regular rate.
Others, such as amino acid racimization and cation-ratio dating, are based on chemical changes in the organic or inorganic composition of a sample. In recent years, a few of these methods have come under close scrutiny as scientists strive to develop the most accurate dating techniques possible.

The real meaning of history is to trace the developments in various fields of the human past. Towards this end, while investigating the past cultures, archaeology depends on various dating methods. These dating methods can broadly be divided into two categories, i. These are mainly non-scientific dating methods. These methods were relied on especially prior to the introduction of scientific methods of dating.
Absolute dating can be achieved through the use of historical records and dating techniques that have had a revolutionary effect on archaeology and geology. objects that appeared in his excavations—a technique known as cross-dating.
View exact match. Display More Results. The basis of cross-dating is the occurrence of finds in association. The assumption is that a particular type of artifact, for example a type of sword, when found in an undated context will bear a similar date to one found in a dated context, thus enabling the whole of the undated context to be given a chronological value.
The method is based on the assumption that typologies evolved at the same rate and in the same way over a wide area or alternatively on assumptions of diffusion. Many of the chronologies constructed before the advent of chronometric dating techniques were based on cross-dating. New techniques such as radiocarbon dating showed some of the links established by cross-dating to be invalid, so the method has become somewhat discredited. However, its use is still helpful where recognizable products of dateable manufacture are found in undated contexts with no possibility of using a chronometric dating technique.
So in the absence of geochronology, two cultural groups can only be proved contemporary by the discovery of links between them. If in culture A an object produced by culture B is found, A must be contemporary with, or later than, B.
Taking the necessary measures to maintain employees’ safety, we continue to operate and accept samples for analysis. History, anthropology, and archaeology are three distinct but closely related bodies of knowledge that tell man of his present by virtue of his past. Historians can tell what cultures thrived in different regions and when they disintegrated. Archaeologists, on the other hand, provide proof of authenticity of a certain artifact or debunk historical or anthropological findings.
Studying the material remains of past human life and activities may not seem important or exciting to the average Joe unlike the biological sciences. It is in knowing what made past cultures cease to exist that could provide the key in making sure that history does not repeat itself.
