暴露于埋藏和风化的生物材料中稳定同位素成分的保存程度仍然是一个有争议的话题。考古骨骼和牙齿的同位素组成在重结晶过程中的变化经常被怀疑，但很难证明。在这里，我们研究了加热（燃烧，煮沸）对磷酸氧（δ 18 Op）的同位素组成的影响骨生物磷灰石从两个现代白尾鹿（Odocoileus virginianus）。我们的实验模拟了烹饪和垃圾处理的做法，这些做法影响了许多考古样本。δ 18 Op的原始值在<300 °C时保持不变。在较高的温度下，值降低了多达7‰的主要组成。从25 ° C到675 °C，仅观察到结晶度（使用FTIR和XRD测量）的微小变化，尽管在300 °C以上δ 180 p发生了较大变化。仅在FTIR CI ≤2.5-2.7时保留δ 18 OP的原始值。XRD CI值在低于10625 °C时对δ 180 p的变化不敏感。
The extent of preservation of stable isotope compositions in biomaterials exposed to burial and weathering continues to be a topic of some debate. Changes in the isotopic composition of archaeological bones and teeth during recrystallization are often suspected, but difficult to prove. Here, we examined the effects of heating (burning, boiling) on the isotopic composition of phosphate oxygen (δ18Op) in bone bioapatite from two modern White-Tailed deer (Odocoileus virginianus). Our experiments simulated cooking and refuse disposal practices, which have affected many archaeological samples. Original values for δ18Opwere preserved at <300 °C. At higher temperatures, values were lowered by as much as 7‰ from primary compositions. Only small changes in crystallinity (measured using FTIR and XRD) were observed from 25 to 675 °C, despite large shifts in δ18Opabove 300 °C. Original values for δ18Opwere preserved only at FTIR CI ≤2.5–2.7. XRD CI values were not sensitive to changes in δ18Opbelow ∼625 °C.
