In that article, Killick, Jull, and Burr suggest that the 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.

Fullen's study of the Sarah Peralta site in Louisiana found that the OCR method served as an effective means of inferring time at the site in the absence of radiometrically dateable charcoal. Submitted to the National Park Service, Atlanta, Georgia.

He concludes that whereas debate remains concerning the OCR procedure, "the well-corroborated dates that the LSU Museum of Natural Science has had returned on material processed with OCR and conventional radiocarbon dating..dates returned on material from Zone 3 will be considered accurate until such time that OCR dating is proven invalid." (ibid. 65) The OCR method has been used in a large number of archaeological and geomorphological studies, and an incomplete list of published references is provided below.

It has been used to evaluate soil development in a range of temperature regimes including arid, Abbott, James T., Raymond Mauldin, Patience E.

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. Pollan 1995 Excavations at Site 41WH24, Wharton Co., Texas.

The method is experimental, and it is not as widely used in archaeology as other chronometric methods such as radiocarbon dating.

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. Prehistoric and Historic Excavations at Site 9Gw347, Annistown Road Improvement Project, Gwinnett County, Georgia.

If the sample is freshly burned there will be no oxidizable carbon because it would have all been removed by the combustion process. [5] Kindall, Sheldon 1997 The Oxidizable Carbon Ratio (OCR) Technique: A New, Low-Cost Dating Method. New South Associates, Inc., Stone Mountain Georgia.

Over time this will change and the amount of organic carbon will decrease to be replaced by oxidizable carbon.
