Sentences with phrase «radiocarbon age calibration»

Not exact matches

Of course, the table, so constructed, will only give the correct calibration if the tree - ring chronology which was used to construct it had placed each ring in the true calendar year in which it grew.Measurements made using specially designed, more elaborate apparatus and more astute sampling - handling techniques have yielded radiocarbon ages for anthracite greater than 70,000 radiocarbon years, the sensitivity limit of this equipment.

If we do this for a series of rings through any given chronology, we can then establish a radiocarbon calibration curve, which allows us to translate any radiocarbon age into a true calendar date.

Archaeologists and other scientists, who are more interested in the radiocarbon dating tool per se, quantify the MRE in their study region and apply the correction in the calibration of marine radiocarbon ages from that particular place.

However, the key point about radiocarbon dating is that the «calibration curve» relationship of «true» radiocarbon age t14C to the true calendar date ti of the event corresponding to the 14C determination is highly nonlinear.

Professor Bronk Ramsey considers that knowledge of the radiocarbon calibration curve does give us quantitative information on the prior for 14C «age».
