Human remains may be compared with animal bone or fossils found in the same strata.Relative dates may be obtained form time-related chemical changes which occur in bone, especially in fluorine, uranium, and nitrogen.
SYNONYMS OR RELATED TERMS: absolute dating; chronometry CATEGORY: technique DEFINITION: Any technique of dating that relies on chronological measurement such as calendars, radiocarbon dates, etc.It is used for human and animal bone and other organic material.Specific changes in its amino acid structure (racemization or epimerization) which occur at a slow, relatively uniform rate, are measured after the organism's death.and which give the result in calendar years before the present, or B. Most of these techniques produce results with a techniques do not.Among the most useful chronometric dating techniques are radiocarbon dating, potassium argon dating, and thermoluminescence dating.
However, racemization is very much affected by environmental factors such as temperature change.
