Oxidizable carbon ratio dating, checklist to succeed in digital project
In spite of the fact that interactions among molecules do not exceed a range of some 10 -8 cm, the system is structured as though each molecule were 'informed' about the overall state of the system. Contribution by Bonn and Hamburg. The paper discusses four samples from Connecticut and West Virginia that gave results that were spurious.
Pennsylvania Archaeologist 69 1: The simplest chemical reactions are first-order differential equations Castellan In conclusion, we cannot at present recommend the addition of OCR to the archaeologist's battery of dating techniques.
Abbott Fort Polk, Louisiana: So we can let you know about creation events in your area. This procedure is based on the chemical analysis of charcoal within definable environmental contexts. Can I encourage you to read the account of the Flood in Genesis chapters 6 to 9. Many of the dates are from difficult-to-obtain sources, such as archaeological sites investigated during the course of cultural resource management projects.
We assume that Frink derived this equation from a purely statistical parametrization of a number of different possible variables.
Radiometric carbon-dating procedures measure the decay of unstable carbon isotopes, following a classical physics model of entropy. Feathers, Stephen Williams, Kristen J. From Casual Dating to a Meaningful Relationship? Although these procedures do not yield the same values for organic carbon, the results obtained from analyses of agricultural topsoils form a constant ratio Hesse What we do carbon ratio dating for sure is that there was a global Flood and that it occurred about 4, years ago. 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.
Journal of Soil Science Frink's calibration curve on 93 soils from North American sites extends to over 10, years before present. 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 It is important to note that the OCR carbon ratio dating method is, like any scientific procedure, subject to testing, evaluation, and refinement.
Archaeology of Eastern North America 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 herringand 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.

The degree of effect for both pH and percent organic carbon was found to be nonlinear, and best modeled using the square-root of these values. Also, we know that the rate constant k has the form: This is stated to be a plot of OCR dates obtained from features independently dated by radiocarbon, or else associated with features of known historical age.
The OCR formula, the specific changes in carbon that are being recorded, and the causal agent s of these changes are hypotheses.
