能够确定一个特定的燧石样品是否在人类使用过程中有意或无意地受到加热，这在考古学上具有重要意义。我们在这里报告了使用ESR光谱对火石的研究，并表明加热的材料可以很容易地通过一个特征ESR信号的出现来识别，而这个信号在未加热的火石中是不存在的。这种信号被认为在不确定的时间内是稳定的。我们还探索了这项技术在燧石检测中的其他含义，包括它在测年方面的可能用途。
IT is of archaeological importance to be able to determine whether or not a particular sample of flint has been subjected to heating, either intentionally or accidentally, during its utilisation by man. We report here on the use of ESR spectroscopy for the study of flint, and show that heated material can be readily identified by the appearance of a characteristic ESR signal which is absent from the unheated flint. This signal is considered to be stable over an indefinite period of time. We have also explored other implications of this technique in the examination of flint, including its possible use for dating purposes.
