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 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.[1][2][3]
