Abstract
This study examines knapping techniques in the production of stone tools made on dolerite to understand the knapping characteristics of this igneous tool stone. Extensive experimental research exists on the knapping of silica-rich materials like flint, yet studies on materials low in silica remain scarce. Dolerite, an igneous rock composed mainly of plagioclase, feldspar, and pyroxene, has been used during the Palaeolithic globally and the Middle Stone Age (MSA) of Africa specifically. We address two questions: (i.) Does the application of different knapping techniques to dolerite produce artifacts with distinguishable attributes? (ii.) Are these attributes similar to or different from those of flint? Using three direct percussion techniques, we created an experimental reference assemblage on dolerite and conducted a quantitative attribute analysis. Our findings indicate that knapping techniques can be distinguished at the assemblage level, with attributes significantly different from flint, highlighting the need for further studies on diverse lithic materials.
