Abstract
This paper focuses on patterns of hunter-gatherer igneous (flaked) toolstone procurement on the Coconino Plateau of northern Arizona. The two-part study combined an X-ray fluorescence (XRF) source sampling survey with an XRF analysis of projectile points. Our focus is on the sources of archaeological obsidian and fine-grained volcanic (FGV) material in the San Francisco and Mount Floyd Volcanic Fields and a sample of Paleoindian and Archaic period igneous projectile points (n = 274) recovered from the area. We update the XRF data for the sources with additional analysis of the geologic source material. We also determine the geologic source for the majority of the points. In addition, this paper presents data on three previously undocumented sources of archaeological toolstone.
