The Investigation of Obsidian Craft Production at Xochicalco, Morelos

Abstract

Abstract Surface reconnaissance at the site of Xochicalco, Morelos, identified 12 areas believed to be production locales where obsidian tools were manufactured during the Epiclassic period (A.D. 700-900). Production locales were identified from concentrations of chipped stone debitage located in both residential and nonresidential contexts at Xochicalco. Differences in the size and location of these production locales suggested obsidian craft activity was carried out in three different production contexts similar to those reported at the large urban center of Teotihuacan: small domestic workshops, large nonresidential workshops, and civic-ceremonial precinct workshops. Stratigraphic excavations were initiated to test whether the inferences about the context of production based on surface concentrations of obsidian debitage would be confirmed by subsurface testing. The results show that in most cases surface concentrations of obsidian debitage accurately reflect the presence of in situ craft activity.
