Radiocarbon calibration and stratigraphic analysis in Archeology: Using the OxCal program

In today's archaeological studies around the world, the use of absolute chronology by radiocarbon or carbon 14 method is common and can even reduce errors due to incorrect stratigraphy and anxious layers for explorers. The accuracy of measurement in this method is very high provided correct sampling, and with the advancement of science and technology, software for specialized and complex calculations to convert and calibrate the results to the calendar age, which used by archaeologists, was created. One of these softwares is OxCal program which can be used for researchers both online and offline. In this paper, in addition to a brief explanation of the method of performing Radiocarbon dating and Calibration, we’ll show you how to use this program to calibrate single, Sequential phases, sub-phases (Contiguous phases) and overlapping phases and also using these analysis.
