Do carbon dating equations

Frink and others have published multiple studies demonstrating that OCR dates can correlate well with radiocarbon dates (see list of published references provided below).

In that article, Killick, Jull, and Burr suggest the that OCR method has (1) never been described in a peer-reviewed journal article, (2) that no "scientifically acceptable" demonstration of the accuracy and precision of OCR dating has been published, and (3) that the equation underlying the OCR method is questionable because of site-specific environmental factors. 1995 A National Register Evaluation of Twelve Sites in Adair, Cumberland and Metcalfe Counties, Kentucky.

Frink's rejoinder to these comments points out that (1) the OCR method has indeed been described in a peer-reviewed journal article , (2) that the accuracy and precision of the method have been reported in multiple venues and that the concept of "scientifically acceptable" is context- and person-specific (and therefore a red herring), and that (3) the equation underlying the OCR method takes into account the seven factors of soil formation, and that these factors are routinely used in soil science applications without question.

In the end, Frink concludes that the OCR method—like any scientific advance—warrants further study, and he points out that even the now venerable "scientifically acceptable" method of radiocarbon dating was much maligned when it was first introduced.

Oxidizable carbon ratio dating is a method of dating in archaeology and earth science that can be used to derive or estimate the age of soil and sediment samples up to 35,000 years old.

The method is considered by some to be experimental, and it is not as widely used in archaeology as other chronometric methods such as radiocarbon dating. Pollan 1995 Excavations at Site 41WH24, Wharton Co., Texas.

The methodology was introduced by Archaeology Consulting Team from Essex Junction in 1992. This dating method works by measuring the ratio of oxidizable carbon to organic carbon. If the sample is freshly burned there will be no oxidizable carbon because it would have all been removed by the combustion process. Prehistoric and Historic Excavations at Site 9Gw347, Annistown Road Improvement Project, Gwinnett County, Georgia. Over time this will change and the amount of organic carbon will decrease to be replaced by oxidizable carbon. [5] Kindall, Sheldon 1997 The Oxidizable Carbon Ratio (OCR) Technique: A New, Low-Cost Dating Method. New South Associates, Inc., Stone Mountain Georgia. By measuring the ratio of oxidized carbon to organic carbon (the OCR) and applying it to the following equation the age of the sample can be determined with a very low standard error.

It is important to note that the OCR dating method is, like any scientific procedure, subject to testing, evaluation, and refinement.
