Warren; Blackwell, Paul G. Robert Whitelaw has done a very good job illustrating this theory using about 30, dates published in Radio Carbon over the last 40 years. Dormant volcanoes can also emit aged carbon. The Pleistocene is a geological epoch that began about 2. Journal of the Franklin Institute. Taylor also suggests that the availability of definite date information freed archaeologists from the need to focus so much of their energy on determining the dates of their finds, and led to an expansion of the questions archaeologists were willing to research.

How Accurate is Carbon Dating?
Quaternary Geochronology. Definitions, mechanisms and prospects" PDF. Thus, as millions of tons of Carbon are pushed into the atmosphere, the steady ratio of these two isotopes is being disrupted. Dating material from one location gives date information about the other location, and the dates are also used to place strata in the overall geological timeline. News section. This effect is known as isotopic fractionation.
