Dating techniques in archeology

Published: 06.03.2018

Samples of Bristlecone pine, a tree with a very long life span, have been dated using both dendrochronology and radiocarbon dating. This page was last edited on 9 March , at

However, seriation only works when variations in a cultural characteristic are due to rapid and significant change over time. In the case of ceramics it can be difficult to identify creamware from pearlware, whiteware and others, but through previous research we know that the paste in creamware is more porous than that of the others and that the glaze is often pooled with a green tint in crevices.

As previously mentioned, radioactive decay refers to the process in which a radioactive form of an element is converted into a decay product at a regular rate.

Thus, the growth pattern of a tree of a known age can be used as a standard to determine the age of similar trees. Changes in pollen zones can also indicate changes in human activities such as massive deforestation or new types of farming. The fresh tracks are counted to date the sample. In addition to the radiocarbon dating technique, scientists have developed other dating methods based on the transformation of one element into another.

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. If the same pottery type is found in another excavation nearby, it is safe to assume that the layers are the same age. Further this formula has been disproved on many occasions. The age of the deposit may be determined by measuring how much of the daughter has formed, providing that neither isotope has entered or exited the deposit after its initial formation.

Radiocarbon dating has had an enormous impact on archaeology. These findings must be classified, which requires more hours of tedious work in a stuffy tent. While collecting samples for radio carbon dating we should take utmost care, and should observe the following principles and methods. Dating techniques are procedures used by scientists to determine the age of a specimen.
