Obsidian is one of the most common materials preserved in the archaeological record of Mesoamerica. Because of this and obsidian's unique chemical properties, it has become one of the most common means by which to explain ancient exchange and production. Northern Belize has largely been absent from discussions of Postclassic Mesoamerican economies. The limited amount of obsidian research that has been done is unable to draw comparisons to the region's primary site during this period, Santa Rita Corozal. This thesis remedies this by exploring the importation, production, and distribution of obsidian at the Postclassic Maya primary center of Santa Rita Corozal, Belize. Through the application of the lithic technology approach and the use of pXRF (portable X-ray fluorescence) spectrometry, it is possible to establish the sources of obsidian being exploited, the stage of reduction of obsidian imports, the major obsidian industry, and obsidian distribution for Santa Rita Corozal's Postclassic Period.
