The analyses of raw material provenance offers the possibility of tracing short and long-distance raw material transport. So far, most studies of raw material of flint and chert in Europe have been based on macroscopic analyses. We apply infrared spectroscopy to Aurignacian assemblages from Vogelherd cave and to the Magdalenian site Randecker Maar in southwestern Germany. We compare raw material samples from three chert-bearing areas in Germany with archaeological samples from Vogelherd. Our results show that infrared spectroscopy can distinguish between different raw materials. Our archaeological samples from Vogelherd correspond to the sampled geological cherts in terms of their spectral signature. Our comparison of reference samples and archaeological samples highlights problems in commonly used macroscopic identifications of chert raw materials.
对原材料产地的分析提供了追溯短途和长途原材料运输的可能性。到目前为止，欧洲对燧石和硅质岩原材料的研究大多基于宏观分析。我们将应用于红外线光谱学分析沃格尔赫德洞穴的阿舍利时期组合和德国西南部的兰代克马遗址的马格德林时期。我们将德国三个产硅石地区的原材料样本与沃格尔赫德的考古样本进行了比较。我们的结果表明，红外线光谱学可以区分不同的原材料。我们从沃格尔赫德采集的考古样本在光谱特征上与所采集的地质硅石一致。我们对参考样本和考古样本的比较突出了常用的宏观鉴定硅质岩原材料的问题。
