Summary

This project involves the analysis of 150 obsidian artifacts from 2 sites in southwestern New Mexico. Compositional analysis was conducted using X-ray fluorescence (XRF) and the resulting chemical compositions were compared to known obsidian sources in the American Southwest, Northern Mexico, and surrounding regions. The majority of the samples (74%) are from Mule Creek, but Mount Taylor and Jemez Mountains sources are also present. Twenty of the samples all belong to the same group of unassigned samples that represents the largest group of unassigned artifacts MURR has analyzed from the Southwest. Six additional samples are not obsidian and are not discussed further other than a listing in the table with source assignments.
