Cultural dating archeology
"cultural dating: estimating the period from which an object came by comparing it to what you already know about various time periods." So it's a big part of what a lot of field archaeologists do.They find, say, an old bit of pottery, and based on what they know about that type of pottery from previous digs and previous conclusions they can make guesses about what time period this new piece fits in.Radiocarbon dating has been around for more than 50 years and has revolutionized archaeology.Carbon 14 dating remains to be a powerful, dependable and widely applicable technique that is invaluable to archaeologists and other scientists.The unstable and radioactive carbon 14, called radiocarbon, is a naturally occurring isotope of the element carbon.When a living thing dies, it stops interacting with the biosphere, and the carbon 14 in it remains unaffected by the biosphere but will naturally undergo decay.
The implication of what is represented by the carbon 14 activity of a sample must be considered.
Decay of carbon 14 takes thousands of years, and it is this wonder of nature that forms the basis of radiocarbon dating and made this carbon 14 analysis a powerful tool in revealing the past.
The process of radiocarbon dating starts with the analysis of the carbon 14 left in a sample.
Some samples, like wood, already ceased interacting with the biosphere and have an apparent age at death and linking them to the age of the deposits around the sample would not be wholly accurate.
There are also cases when the association between the sample and the deposit is not apparent or easily understood.
