Carbon dating limit


It's development revolutionized archaeology by providing a means of dating deposits independent of artifacts and local stratigraphic sequences. Libby in 1949, and has become an indispensable part of the archaeologist's tool kit since.Radiocarbon, or Carbon-14, dating is probably one of the most widely used and best known absolute dating methods. Radiocarbon dating relies on a simple natural phenomenon.



Shell may succumb to isotopic exchange if it interacts with carbon from percolating ground acids or recrystallization when shell aragonite transforms to calcite and involves the exchange of modern calcite.As the Earth's upper atmosphere is bombarded by cosmic radiation, atmospheric nitrogen is broken down into an unstable isotope of carbon - carbon 14 (C-14).The unstable isotope is brought to Earth by atmospheric activity, such as storms, and becomes fixed in the biosphere.Radiocarbon analyses are carried out at specialized laboratories around the world (see a list of labs at: When a biological organism dies, the radioactive carbon in its body begins to break down or decay.

This process of decay occurs at a regular rate and can be measured.

This is actually a mini-simulator, in that it processes a different sample each time and generates different dates.
