Quarry sites contain thousands of years of debitage in quantities that can be studied statistically. Paradoxically, quarry sites, unlike other types of sites, have not been subjected to routine archaeological inquiry. This article describes procedures being used in Florida to resolve questions about lithic technology and the antiquity of chert quarries. The enduring consequence of the research is the realization that extraction methods utilized by prehistoric stoneworkers were applied eventually to other technologies and that the data resulting from the studies have implications extending beyond archaeological interests. The materials and methods are explained; of particular importance are weathering studies, thermoluminescence dating, and pedological studies.
