Description

<jats:title>Abstract</jats:title><jats:p> This study explores the early use of obsidian at the Maya site of Colha in northern Belize and the implications that variations in source distribution have for the site and its regional connections. Energy dispersive x-ray fluorescence (EDXRF) analysis of 104 specimens of obsidian from Preclassic contexts at the site identified El Chayal obsidian as the most common overall followed closely by that from San Martin Jilotepeque. Ixtepeque obsidian, not common in many Preclassic assemblages, was also strongly represented. The results revealed a Middle Preclassic dependence on San Martin obsidian gradually diminishing through the Preclassic to the Classic period, when San Martin all but disappears from the site. A corresponding increase in El Chayal obsidian use through time at Colha coincides with the rise of Kaminaljuyu in the Guatemalan highlands. Analysis of the obsidian by context indicated that El Chayal obsidian dominated in architectural and ritual deposits while Ixtepeque obsidian was the most common in workshops. San Martin accounted for a slightly greater percentage than El Chayal obsidian in middens, with Ixtepeque materials notably less common. The data indicate that Colha was connected to a broad distribution network from the Middle Preclassic onward, and that obsidian source variability was greater during the Preclassic than the subsequent Classic period.</jats:p>
