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 reexamine possible causes of a west–east cline in maximum lithic raw material transfer...

Sensitivity tests comparing three different paleotopographic settings. Palaeogeogr,, Palaeoclimatol., Palaeoecol., 95: 229-252. Topography and location of continents largely determine present-day climate. We conclude that in the geologic past paleotopographic ...
