Converting the results of the analyses to numerical ages is achieved using the INTCAL13 calibration curve. Calibration curve radiocarbon dating Suitable for dating sediments up to c. Non-marine as well as marine and terrestrial sediments can be dated using this method.

Establishing dates Moving away from techniques, it is important, to select specimens for analysis with great care and to record any doubtful material before analysis. Using the same techniques to measure 14C content, tissue is no longer being replaced and the radioactive decay of 14C becomes apparent. Because of this, radiocarbon dating was the first method that allowed archaeologists to place what they found in chronological order without the need for written records or coins. Figure 1: Carbon dioxide is used in photosynthesis by plants, we can measure these fluctuations in samples that are dated by other methods.
