On the “Making” of an Assemblage of Stone Tools

An attempt is made to view an assemblage of stone tools as something in the process of being generated over time. A formal model is developed which includes variables such as activities and tool types and also draws attention to somewhat less visible variables that enter into the formation of an assemblage such as the dropping rates of tools and mapping relations between tool types and activities. Implications of the model for the interpretation of correlation coefficients which are often used in the quantitative analysis of assemblages and also for the "functional" argument are discussed.
