Travertine is calcium carbonate precipitated from groundwater and spring water, and is widely distributed in northwest Iran. It is one of the suitable samples which can reconstruct paleoenvironment on land with a high resolution.In this study, I first determine the formation age of the travertine and then reveal its source by a series of data of 14C, δ13C, δ18O, 87Sr/86Sr and major- and trace-elemental compositions.

Burned bones may not provide accurate 14C dating because of no remain of collagen, an organic fraction in bone, suffered from heating. It is a very crucial assignment to enable burned bone to be 14C-dated. The purpose of this study is to test the reliability of 14C dating of carbonate hydroxyapatite (CHa), an inorganic fraction in bone, by using some burned bones from archaeological sites. The samples tested are five burned bones with gray to black colors of known-age collected from the Göytepe and Damjili Cave archeological sites in Azerbaijan. The XRD patterns of the bones showed that they had not suffered from the heat of >600ºC, and that they have low crystallinity of apatite. The 14C dates of the Göytepe and Damjili Cave bones were younger than the dates obtained by charred materials excavated from the same layer for 400 years and 1000–1700 years, respectively. The results indicate that the bones burned at the low temperature (<600ºC) have been heavily contaminated through diagenetic alteration during burial because of low crystallinity of apatite, and that the contaminants can not be removed from bone CHa by chemical treatment used in this study. In conclusion, secondary carbonate can be removed from even bones burned at low temperature (<600ºC) by acetic acid treatment, while exogenous carbon included into the inner site of CHa can not be removed. The degree of contamination from foreign carbon in bone samples varies with burial condition. Therefore, it is important to check the apatite crystallinity of bone and burial environment of bones to perform reliable 14C dating using bone CHa.遺跡に埋没している被熱骨に対し，炭酸ヒドロキシアパタイトを用いて信頼性のある14C年代測定が可能であるかを検証した．用いた試料は，アゼルバイジャンのギョイテペ遺跡とダムジリ洞窟遺跡から出土した被熱動物骨7点である．これらの骨試料の炭酸ヒドロキシアパタイトの14C年代は，同層から得られた炭化植物片の年代よりも，ギョイテペ遺跡においては400年，ダムジリ洞窟遺跡においては1000-1700年程度若くなった.XRDパターン結果から，二次的に付着した炭酸塩は，試料の酢酸処理によって除去されていると考えられ，若くなった原因は，炭酸ヒドロキシアパタイト結晶内に入り込んだ汚染炭素によるものと考えられる．ギョイテペ遺跡とダムジリ洞窟遺跡遺跡による年代差は，ギョイテペ遺跡の周辺は火成岩が，ダムジリ洞窟の周辺は石灰岩が分布していて土壌環境が異なっていたためと考えられる．今後さらに，埋没環境，被熱温度が異なる骨試料に対し，炭酸ヒドロキシアパタイトを用いて信頼性のある14C年代を得るための検討を行なっていく必要がある．
