在本文中，我们研究的方法来预测分布的硅质岩在欧洲，使用贝叶斯技术被称为“权重的证据”。我们使用的技术来分类基岩地质构造的可能性，产生工具质量的石器原料，我们使用的结果，重新审视可能的原因，西-东倾斜的最大石器原料转移距离时观察到的比较网站在欧洲的中，上旧石器时代。从我们的研究结果中可以明显看出，沿沿着东西向倾斜带，高度预测工具质量岩石的地质构造丰度下降，主要反映了侏罗纪和白垩纪含硅质岩沉积物丰度的下降。我们的研究结果是一致的解释旧石器时代晚期的转移距离记录，表明特殊目的的采购。
In this paper we examine ways to predict the distribution of siliceous rock in Europe, using a Bayesian technique known as ‘Weights-of-Evidence’. We use the technique to classify bedrock geological formations in terms of their likelihood of yielding tool-quality lithic raw materials, and we use the results to re-examine possible causes of a west–east cline in maximum lithic raw material transfer distances observed when comparing sites in both Middle and Upper Palaeolithic Europe. It is evident from our results that there is a decline in abundance of geological formations highly predictive of tool-quality rock along a west–east cline, predominantly reflecting a decrease in abundance of Jurassic and Cretaceous chert-bearing sedimentaries. Our results are consistent with an interpretation of the Upper Palaeolithic record of transfer distances as indicating special-purpose procurement.
