Summary

Chemical analysis of obsidian is a useful proxy for studying the control of obsidian goods exchange and the presence of pre-Hispanic geopolitical boundaries. Recent studies on obsidian sourcing show that during the Late Postclassic period (A.D. 1250-1519), regional altepemeh imported obsidian from several sources within highland Mesoamerica. Analysis of data suggests that no single political entity fully controlled the distribution of obsidian goods from a particular source, suggesting that perhaps a single obsidian source was geopolitically exploited by several rival altepemeh. In order to examine this issue, we used pXRF analysis to analyze variation in sub-flow chemical signatures of 20 locations within the Zaragoza-Oyameles source area (located in Puebla, Mexico). Results were then compared to chemical signatures of archaeological obsidian artifacts from Late Postclassic sites of the Puebla-Tlaxcala region. Here, we present our preliminary results with special reference to the economic relationship between competing rival political entities.
