Talk:Dendrochronology

The following was stated in the article:

"This finding showed the current model for carbon-14 dating to be incorrect, so scientists recalibrated their C-14 model based on this tree."

I never read this. What is the source of this info? Creationist 23:01, 13 January 2006 (GMT)creationist


 * The further reading pages state "Because the ratio of 14C to 12C in the atmosphere varies over time, raw radiocarbon "dates" are calibrated to obtain actual calendar dates using dendrochronology. This process of calibration is an essential part of the radiocarbon dating method, and eliminates assumptions about historical atmospheric radiocarbon concentrations and the constancy of the decay rate of radiocaron over time. (See How does the radiocarbon dating method work?) Dendrochronology thus provides an essential service to radiocarbon dating, the major method used to date archaeological remains, guaranteeing its accuracy throughout the period of interest to biblical chronology."

"Tree ring dating (dendrochronology) has been used in an attempt to extend the calibration of carbon-14 dating earlier than historical records allow. The oldest living trees, such as the Bristlecone Pines (Pinus longaeva) of the White Mountains of Eastern California, were dated in 1957 by counting tree rings at 4,723 years old. This would mean they pre-dated the Flood which occurred around 4,350 years ago, taking a straightforward approach to Biblical chronology." 

I did not see where it was implicitly stated that the model was changed, but they do say that the current C-14 model incorporates dendrochronology. PrometheusX303 00:29, 14 January 2006 (GMT)
