| Outline of Final Research Achievements |
The purpose of this study is to examine whether or not inorganic carbonate hydroxyapatite (CHa) in a cremated bone, which remains little organic collagen, can provide accurate radiocarbon (C14) dates. The obtained results are as follows: 1) The cremated bone suffering from heat at the high temperature more than 750°C have high crystalline of apatite and are not easily contaminated by exogenous contaminants during burial, 2) Sample treatment of a cremated bone with 0.1 mol/L acetic acid for 1 h under vacuum can remove secondary carbonate and foreign carbon effectively to extract innate carbon in the bone CHa, and 3) The CHa in cremated bone with high crystalline of apatite is useful for accurate C14 dating.
