Some examples of the types of material that radiocarbon can determine the ages of are wood, charcoal, marine and freshwater shell, bone and antler, and peat and organic-bearing sediments.
Age determinations can also be obtained from carbonate deposits such as calcite, dissolved carbon dioxide, and carbonates in ocean, lake, and groundwater sources.
In the following section we are going to go more in-depth about carbon dating in order to help you get a better understanding of how it works.
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.
This allowed for the establishment of world-wide chronologies.
When the organism dies, the ratio of C-14 within its carcass begins to gradually decrease.
The rate of decrease is 1/2 the quantity at death every 5,730 years. The animation provides an example of how this logarithmic decay occurs.

C-14 Decay Profile Clicking on the "Show Movie" button below will bring up an animation that illustrates how a C-14 sample is processed and the calculations involved in arriving at a date.Maybe one in a trillion carbon atoms are carbon-14.Both Carbon-12 and Carbon-13 are stable, but Carbon-14 decays by very weak beta decay to nitrogen-14 with a half-life of approximately 5,730 years. It's development revolutionized archaeology by providing a means of dating deposits independent of artifacts and local stratigraphic sequences.
