For those researchers working in the field of human history, the chronology of events remains a major element of reflection. Archaeologists have access to various techniques for dating archaeological sites or the objects found on those sites. There are two main categories of dating methods in archaeology : indirect or relative dating and absolute dating. Relative dating includes methods that rely on the analysis of comparative data or the context eg, geological, regional, cultural in which the object one wishes to date is found. This approach helps to order events chronologically but it does not provide the absolute age of an object expressed in years. Relative dating includes different techniques, but the most commonly used are soil stratigraphy analysis and typology. On the other hand, absolute dating includes all methods that provide figures about the real estimated age of archaeological objects or occupations. These methods usually analyze physicochemical transformation phenomena whose rate are known or can be estimated relatively well. This is the only type of techniques that can help clarifying the actual age of an object.

Thermoluminescence dating TL is the determination, by means of measuring the accumulated radiation dose, of the time elapsed since material containing crystalline minerals was either heated lava , ceramics or exposed to sunlight sediments. As a crystalline material is heated during measurements, the process of thermoluminescence starts. Thermoluminescence emits a weak light signal that is proportional to the radiation dose absorbed by the material. It is a type of luminescence dating.

Sediments are more expensive to date. It will often work well with stones that have been heated by fire.

When Is It Dated? Dating Methods and Archaeology

Dendrochronology is the study of data from tree ring growth. Due to the sweeping and diverse applications of this data, specialists can come from many academic disciplines. There are no degrees in dendrochronology because though it is useful across the board, the method itself is fairly limited. Most people who enter into studying tree rings typically come from one of several disciplines:.

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.

But, even when the scientific methods of absolute dating are available, this method of dating has not lost its importance, as many a time we have to depend solely on relative dating. Even when the absolute dates are available, we have to supplement the information with relative dating.

Petrie explained sequence dating to work back from the absolute historical phases of Egypt into pre-dynastic Neolithic times, using groups of contemporary artefacts explained together at a single time in graves. Seriation Cross-dating was developed in the USA to place in order finds from strata or absolute kinds of assemblages such as potsherds done from the surface of sites. The extent of documentation explained considerably in ‘historical’ cultures and the information that survives is determined by a variety of factors.

If a context containing burnt debris and broken artefacts is excavated on a site from a historical period, it is tempting to search the local historical framework for references to warfare or a disaster in the region, and to date the excavated context accordingly. The activity that uses tree rings dated to their exact year of formation to analyze temporal and spatial patterns of processes in the physical and cultural sciences.

In geology, rock or superficial deposits, fossils and lithology can be used to correlate one stratigraphic column with another. Prior to the discovery of radiometric dating which provided a means of absolute dating in the early 20th century, archaeologists and geologists used this technique to determine ages of materials.

Engaged Archaeology. The first step in an archaeological excavation is surveying the area. This can be done either with remote sensing or direct visual observation. Archaeologists conducting a survey. Archaeologists also use non-invasive techniques to survey sites known as remote sensing. There are many methods including aerial photography which is simply taking pictures from an airplane, hot air balloon or even a remote controlled drone; ground penetrating radar which is used to locate artifacts hidden below ground, and LIDAR, which uses lasers to scan the surface from the air through vegetation.

They start by setting up a grid and connecting the grid to a datum. A datum is a fixed reference point, often one placed by the U. A USGS datum. The next step is to dig several test pits.
