1-3 (3 Records)
A sample of over 800 obsidian projectile points collected during 40 years of archaeological survey and excavation on Fort Bliss Military Reservation of south-central New Mexico and western Texas was submitted for chemical characterization and source identification using X-ray fluorescence (XRF). Obsidian projectile points representing all major temporal periods were analyzed, including Paleoindian Folsom points, several forms of dart points produced during the Early, Middle, and Late Archaic...
Elemental and Isotopic Variability in Mogollon-Datil Province Archaeological Obsidian, Western New Mexico (2015)
The Mogollon-Datil Volcanic Province in western New Mexico has been a subject of geological and geoarchaeological research for over three decades. These Tertiary Period major events incorporated significant areas of crust over tens of thousands of km2 and the rhyolite glass produced from these events are consequently similar in elemental composition even though the five major sources are isolated over a 100 linear km radius, and cross a number of cultural territorial boundaries in the late...
Obsidian Procurement Strategies at the Harris Site (2016)
The Harris Site is a large pithouse village in the Mimbres Valley of southwestern New Mexico. Many of the twenty structures (recently excavated) are organized into five discrete clusters that have been interpreted as the remains of extended family corporate groups. Some of these groups apparently had more wealth and social power, and these differences may be tied to both land tenure and ritual sponsorship. We use obsidian provenance data to explore differences in obsidian procurement strategies...
