A team at the University of Bristol has developed a new method of dating pottery which is allowing archaeologists to date prehistoric finds from across the world with remarkable accuracy. The exciting new method, reported in detail today in the journal Nature , is now being used to date pottery from a range of key sites up to 8, years old in Britain, Europe and Africa. Archaeological pottery has been used to date archaeological sites for more than a century, and from the Roman period onwards can offer quite precise dating. But further back in time, for example at the prehistoric sites of the earliest Neolithic farmers, accurate dating becomes more difficult because the kinds of pottery are often less distinctive and there are no coins or historical records to give context. This is where radiocarbon dating, also known as 14C-dating, comes to the rescue.

Dating refers to the archaeological tool to date artefacts and sites, and to properly construct history. Relative techniques can determine the sequence of events but not the precise date of an event, making these methods unreliable. This method includes carbon dating and thermoluminescence. The first method was based on radioactive elements whose property of decay occurs at a constant rate, known as the half-life of the isotope. Today, many different radioactive elements have been used, but the most famous absolute dating method is radiocarbon dating, which uses the isotope 14 C. This isotope, which can be found in organic materials and can be used only to date organic materials, has been incorrectly used by many to make dating assumptions for non-organic material such as stone buildings.

Question: What Is The Most Accurate Dating Method?

Carbon 14 has a relatively short half-life, which makes it useful only to date once-living organisms that are known or suspected to be less than about thousand years old. But there are many other isotopes that can be used to date rocks and the fossils found within them, and the process works the same way. Also, the correct isoptope must be used to test the age of the object. Some isotopes have a very, very long half-life, and those isotopes can only be used to test objects that are, of course, very old. Use that same isotope to date a rock that just left the mouth of a volcano two weeks ago, and you will get a false reading.

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.
