This is an abstract from the "Taphonomy in Focus: Current Approaches to Site Formation and Social Stratigraphy" session, at the 89th annual meeting of the Society for American Archaeology. We are living through an era that has been described as “the apotheosis of waste,” a globe brimming with greenhouse gasses, mountains of tailings, lagoons of pig-shit, and hangars of acidic sludge. The massive scale and persistence of industrial waste has not only transformed the air, water, and soil that...

In the archaeology of the Sierras Centrales of Argentina more than one hundred years ago studies reported the presence of a lithic technology centered on the use of quartz as a predominant raw material. However, little effort has been made to try to characterize its chemical composition so as to understand the circuits of mobility or the exchange networks in the archaeological sites of the region. The results of provenance studies have allowed us to advance in a geochemical characterization of...

This paper aims to discuss how the success of community partnership has led to an understanding of the way people moved across the landscape in the past. Situated in northern New Mexico, the Pueblo de Abiquiú contains a rich history that dates back at least into 2,800 – 4,000 BP (Before Present). Using portable x-ray fluorescence spectrometry, obsidian artifacts found at the pueblo suggests that groups are bringing obsidian from at least three known local sources. However, there is an...

This is an abstract from the "The Arch Street Project: Multidisciplinary Research of a Philadelphia Cemetery" session, at the 89th annual meeting of the Society for American Archaeology. During early excavations of the Arch Street Project collection, remains were commingled. Reassembling commingled remains is a long, difficult, and technically advanced process that can take years if not decades to complete. This study uses XRF on eight individuals from the Arch Street Project to assess the...

This is an abstract from the "SAA 2024: Individual Abstracts" session, at the 89th annual meeting of the Society for American Archaeology. The acquisition of metal tools on the Spanish Colonial frontier of New Mexico was a rare occurrence, but it is an activity we may be able to better understand through analysis of their production, modification, and utilization as well as sourcing their elemental makeup through XRF. Metals of various types were utilized by settlers for agriculture, cooking,...
