Archaeologists use many different techniques to determine the age of a particular artifact, site, or part of a site. Two broad categories of dating or chronometric techniques that archaeologists use are called relative and absolute dating. Stratigraphy is the oldest of the relative dating methods that archaeologists use to date things. Stratigraphy is based on the law of superposition-like a layer cake, the lowest layers must have been formed first. In other words, artifacts found in the upper layers of a site will have been deposited more recently than those found in the lower layers.
As an example Pinnacle Point 's caves, in the southern coast of South Africaprovided evidence that marine resources shellfish have been regularly exploited by humans as ofyears ago. It was the case of an 18th-century sloop whose excavation was led in South Carolina United States in Dating material drawn from the archaeological record can be made by a direct study of an artifactor may be deduced by association with materials found in the context the item is drawn from or inferred by its point of discovery in the sequence relative to datable contexts.
Dating is carried out mainly post excavationbut to support good practice, some preliminary dating work called "spot dating" is usually run in tandem with excavation.
Dating is very important in archaeology for constructing models of the past, as it relies on the integrity of dateable objects and samples. Many disciplines of archaeological science are concerned with dating evidence, but in practice several different dating techniques must be applied in some circumstances, thus dating evidence for much of an archaeological sequence recorded during excavation requires matching information from known absolute or some associated steps, with a careful study of stratigraphic relationships.
In addition, because of its particular relation with past human presence or past human activity, archaeology uses almost all the dating methods that it shares with the other sciences, but with some particular variations, like the following:. Seriation is a relative dating method see, above, the list of relative dating methods. An example of a practical application of seriation, is the comparison of the known style of artifacts such as stone tools or pottery.
Mar 17, Dating refers to the archaeological tool to date artefacts and sites, and to properly construct history. All methods can be classified into two basic categories: a) Relative dating methods: Based on a discipline of geology called stratigraphy, rock layers are used to decipher the sequence of historical geological ektaparksville.com: Johnblack.
The stratigraphy of an archaeological site can be used to date, or refine the date, of particular activities "contexts" on that site.
For example, if a context is sealed between two other contexts of known date, it can be inferred that the middle context must date to between those dates. From Wikipedia, the free encyclopedia. Main article: Relative dating.
Relative dating determines the age of artifacts or site, as older or younger or the same age as others, but does not produce precise dates. Absolute dating, methods that produce specific chronological dates for objects and occupations, was not available to archaeology until well into the 20th century.

It involves laboratory work and experiments. Historical Archaeology: Historical archaeology involves the study of historical sites, artifacts and any other historical evidence that can provide help in analyzing the different cts related to them.
It usually focuses on the written records left by the ancient races.
Archaeologists collect important clues and historical documents that help them to arrange the cultural chronology of the ancient cultures.
Archaeologists are aware of the fact that historical documents or records may not provide the correction information so they expand their area of study to explore the history to ensure precision of analysis.
Pseudo- Archaeology: Pseudo-archaeology is another type of archaeology that takes into consideration the real and imagined proofs to study the ancient cultures. It is a non-scientific approach that normally collects the evidences giving information about the lost continents such as Mu and Atlantis.

Underwater Archaeology: It is a type of archaeology that deals with the proofs and evidences found under the water. For instance, archaeologists collect proofs regarding shipwrecks, water-buried cities, and certain other swamped archaeological sites. Archaeologists working under this sub-discipline usually collect proofs from underwater making use of excavating tools. Above mentioned are some of the different types or sub-disciplines of archaeology.
In addition to them, there are certain other branches of archaeology that deal with the upkeep and supervision of cultural resources, world heritage, historical monuments, artifacts and other related archaeological sites.
Archaeology is broader term that covers several different areas. Those who study archeology can work as regional archaeologists, research archaeologists, collections manager, archaeological surveyors, and in academic positions.
On The Basis Of Nature Of Work

Feb 22, Following are given different types of archaeology: Archaeometry: It is also referred to as archaeological science. It focuses on the study of the archaeology. It involves application of scientific methods and techniques such as radiocarbon dating, dendrochronology, mathematical methods, microscopes, environmental studies, remote- sensing and. Archaeology has been categorized into various types on the basis of nature of the work involved in the process of data collection and analysis. This depends to a large extent on where an excavation or an exploration is taking place, and with what point of view an archaeologist wants to interpret history. dating methods in archaeology Archaeological investigations have no meaning unless the chronological sequence of the events are reconstructed faithfully. The real meaning of history is to trace the developments in various fields of the human past.
Different Types of Archaeology Archaeology is an academic discipline which is considered as multidisciplinary science because of that fact that it covers several different subject including biology, chemistry, history, geology and art.
