This is an abstract from the "Current Research and On Going Projects at the J Richard Steffy Ship Reconstruction Laboratory" session, at the 2019 annual meeting of the Society for Historical Archaeology. The site of Bridgetown, Antigua lies on the east side of Willoughby Bay near the Crossroads Rehabilitation facility owned and founded by musician, Eric Clapton. The site holds the remains of a town and associated harbour designated as a commerce center in a law regulating trade and taxes on...

Prehistoric human occupation in Southern Ontario, Canada spans the gamut of ephemeral hunter-gatherer usage to intensive Iroquoian village settlements. ITRAX core scanning has the capacity to explore some of this rich history. Initially developed for environmental core analysis, ITRAX technology can highlight differences in culturally generated chemical signatures between intensive and ephemeral occupations. This automated, non destructive x-ray fluorescence (XRF) analysis has the potential to...

In the Middle Ohio Valley, the Early Fort Ancient period (AD 1000 – 1200) saw significant changes to social organization reflected in the built environment. Among the most archaeologically visible of these developments was a new style of settlement – the formal village – typically consisting of spatially differentiated zones arranged in concentric circles. This study selects two Early Fort Ancient village sites from the Cincinnati area, Guard (12D29) and Turpin (33HA19); each site displays...

This study inquires into the obsidian commercial networks of Late Formative in the site of Xochitecatl-Cacaxtla employing an analysis of pXRF on 102 pieces of obsidian artifacts. In addition, we performed a technological approach of the material recovered from ceremonial and domestic contexts in order to know in which stage of the process did it arrive. With this, we intent to know how each source was represented throughout the site, revealing the internal maneuvers used by two different...

We performed morphotechnical and trace element analysis of 2871 obsidian artifacts recovered during survey and excavation from 12 archaeological sites in the Department of Chinandega, in northwest Nicaragua. The elemental analysis was conducted using the Bruker Tracer III-V portable X-Ray Fluorescence (pXRF) spectrometer. The pXRF spectra and elemental concentrations of artifacts were compared with those of known source provenience. The results show 98 percent of the specimens match the...

X-ray fluorescence (XRF) spectroscopy was used to study obsidian artifacts collected from the Trappers Point Site, a multicomponent Early Archaic pronghorn processing site, located west of Pinedale, Wyoming in Sublette County. The trace element concentrations for artifacts were compared to trace element concentrations from known sources. The majority (80%) of the identified materials were from the closest sources in Jackson Hole. The rest came from Obsidian Cliff in Yellowstone National Park and...

We used X-Ray fluorescence (XRF) spectroscopy to identify nine obsidian sources used by the prehistoric inhabitants of Jackson Hole, Wyoming. This paper examines this prehistoric use of obsidian and obsidian sources. Variation in utilization patterns is suggested through study of temporally diagnostic obsidian artifacts. The diachronic pattern of sources used allows consideration of the influences in acquisition, distribution, and use of obsidian.

XRF (x-ray fluorescence) spectroscopy was used to study obsidian artifacts collected from the Helen Lookingbill site (48FR308). The site is located in the southern Absaroka Mountains, a part of the Central Rocky Mountains of Wyoming. Using XRF, the trace element proportions for artifacts were compared to trace element proportions for known sources to identify the sources of the artifacts. The artifacts were produced from four obsidian sources west and northwest of the site. The pattern of...

This poster explores the potential applications of using x-ray fluorescence data to assess site integrity and site formation processes. The subject of the analysis was the fire-modified rock assemblage from the University of Iowa Field School at Woodpecker Cave (13JH202), a Late-Woodland rock shelter. The assemblage was selected because of their ubiquity throughout the site, their likely sourcing from the adjacent limestone cliff face, and association with known cultural horizons. The assemblage...

This is an abstract from the session entitled "Current Research at Texas A&M University's Conservation Research Laboratory" , at the 2022 annual meeting of the Society for Historical Archaeology. At the Texas A&M Conservation Research Laboratory, we pride ourselves on the breadth and quality of our research capabilities. Among these capabilities, x-ray fluorescence allows us to study the elemental composition of objects under our care. We use this tool to accomplish a number of goals, such as...
