AN ENERGY-DISPERSIVE X-RAY FLUORESCENCE ANALYSIS OF OBSIDIAN ARTIFACTS FROM AZ AA:12:85 (ASM), CENTRAL, ARZIZONA
Abstract
The one piece of obsidian debitage was produced from the Sand Tanks source located in western Maricopa County, Arizona (Shackley 2005, Shackley and Tucker 2001). This source is relatively uncommon in archaeological contexts, but has occurred in central Arizona sites (Shackley and Tucker 2001).
