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.

Dating methods. Dating techniques are procedures used by scientists to determine the age of a specimen. Relative dating methods tell only if one sample is older or younger than another sample; absolute dating methods provide a date in years. The latter . Absolute dating is used to determine a precise age of a rock or fossil through radiometric dating methods. This uses radioactive minerals that occur in rocks and fossils almost like a geological clock. It's often much easier to date volcanic rocks than the fossils themselves or the sedimentary rocks they are found in. So, often layers of. 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. Towards this end, while investigating the past cultures, archaeology depends on various dating.

Periods Eras Epochs. Several sets of rings from different trees are matched to build an average sequence.
Subsequently, overlapping series of average sequences from trees that died at different times and come from various sources ie, the wood of historic buildings, archaeological and fossil woods are used to build a chronological sequence covering several hundred years which becomes a reference.
Finally, absolute dating is obtained by synchronizing the average sequences with series of live and thus datable trees and thus anchors the tree-ring chronology in time.
Dendrochronology mainly uses softwood species that are sensitive to changes in growth conditions, while hardwoods show rather little variation in ring width. This method provides very accurate dating, sometimes to the nearest year.
It is especially used to develop calibration curves used to correct data obtained from radiocarbon dating, a technique that remains imprecise due to fluctuations in the concentration of carbon 14 in the atmosphere over the centuries.
Thermoluminescence Thermoluminescence uses the phenomenon of ionizing radiations that naturally occur in the atmosphere. This technique relies on a unique physicochemical property of certain minerals especially quartz and feldspar that have an imperfect structure and therefore retain radioactive elements in the natural environment.
When these minerals are heated while a pot is being baked during the occupation of an archaeological site, for instance, the traps formed by their crystal structure are emptied and the clock is reset to zero. Subsequently, the total flow rate of irradiation paleodose since the reset is calculated by heating the specimen once more, and this result is then compared to the annual input recorded by a dosimeter installed on the archaeological site where the object being dated was found.
Thermoluminescence is a technique that requires complex manipulation. To obtain a date for a single pottery sample, it is necessary to perform a laboratory fractionation of the clay mineral used in the manufacture of the pottery and prepare nearly 75 sub-samples; some of these are heated to release the level of thermoluminescence, while others receive a radiation dose to measure their sensitivity to radiation.
Thermoluminescence can replace radiocarbon dating to date events that occurred more than 50 years ago; it is used mainly for dating stone fireplaces, ceramics and fire remains. Taylor and M.

Radiocarbon dating, often simply called carbon dating, is one of the most well-known techniques of analysis in archaeology. Radiocarbon dating helps archaeologists determine the age of different artefacts. If an artefact has organic material, and thus the radioactive element of radiocarbon, then this method can be used.
