| Abstract: | Understanding the nature of the physical properties of lithic raw materials is a pre-requisite for developing more reliable interpretations of use-wear evidence and tool function. We use nanoindentation and use-wear experimentation as a way to measure differences in raw material surface hardness and roughness in order to show that differences in lithic material properties have implications for rates of use-wear accrual. |
