The material record can give us valuable information about what resources were used at a given archaeological site. In this study, I have used obsidian and its distribution as a proxy for access to resources. By determining which obsidian sources were used and by whom, we can begin to understand the differential access to resources which is paramount to understanding social inequalities. This research uses a combination of visual sourcing and XRF geochemical sourcing to identify patterns in volcanic sources of obsidian artifacts at Post-classic San Felipe Aztatán in Nayarit, Mexico. Despite excellent quality sources being easily accessible, more sophisticated lithic reduction techniques such as prismatic blade production, seem to have been used only with more distant sources. With no substantial qualitative differences among obsidian sources, purely social factors likely resulted in the temporal and spatial distribution patterns at San Felipe Aztatán. Here, the limited area in which Pachuca obsidian is found may indicate an area of elite residence or elite activity, while its limited temporal distribution may reflect the emergence of trade and influence of the Aztatlán tradition dating to the Amapa phase during the Classic Period (500–750 CE). This research may have greater application for other sites across space and time. If obsidian source can be utilized to identify social stratification, we may be able to understand the spatial and social organization of specific sites as well as the complex dynamic trading relationships among sites.
