A sample requires 10 to 20 grams of matter and usually consists of charred organic material, mainly charcoal, but bones see zooarchaeology and shells can also be dated using this technique. An initial reading dates the specimen which is then calibrated by considering this date and its correspondence with the measurable level of carbon 14 stored over time in the growth rings of certain tree species, including redwood and pine bristol.

Subsequently, the calibration of that date provides a time interval where the event or object being dated can be situated eg, AD. Radiocarbon dating, however, can only be used for dating objects that are less than 50 years. Dendrochronology Dendrochronology is a method that studies the rings of tree trunks to define characteristic sequences by analyzing the morphology of growth rings for a given species. This method is based on the principle that the variation in tree growth from one year to another is influenced by the degree of precipitation, sunshine, temperature, soil type and all ambient conditions and that, consequently, reference patterns can be distinguished.

Absolute vs relative dating techniques

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. Aitken editors , Chronometric Dating in Archaeology ; W. Adams, Archaeological Typology and Practical Reality:
