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, years old. The method is experimental, and it is not as widely used in archaeology as other chronometric methods such as radiocarbon dating. 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. Over time this will change and the amount of organic carbon will decrease to be replaced by oxidizable carbon. 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.

Showing Their Age
Archaeology is one of Kelley's great passions. He's read many books on the subject, as well as every issue of "Archaeology" since In times past, things that appeared old were simply considered old, maybe as old as the story of Atlantis, the biblical flood or the earth itself, but nobody knew for certain how old anything was.
Dead Sea Scrolls: What are They? The Dead Sea Scrolls have been called the greatest manuscript discovery of modern times. They were discovered between and in eleven caves along the northwest shore of the Dead Sea. This is an arid region 13 miles east of Jerusalem and 1, feet below sea level. The Dead Sea Scrolls are comprised of the remains of approximately to separate scrolls, represented by tens of thousands of fragments.
