The construction of large stone fortresses, the casteddi, is a defining phenomenon of the Bronze Age period of the Mediterranean island of Corsica (France). However, the function and the precise chronological setting of these structures are still debated. The summer 2015 preventive intervention at the fortress of Cuccuruzzu has revealed some new information on the socio-economic context of ceramic production during the Final Bronze Age (1200-850 BC). The typological study of the material...
Using Geochemistry To Differentiate Copper On The Spanish Colonial Frontier (2020)
This is an abstract from the session entitled "Plus Ultra: An examination of current research in Spanish Colonial/Iberian Underwater and Terrestrial Archaeology in the Western Hemisphere." , at the 2020 annual meeting of the Society for Historical Archaeology. Over the past three years, more than 200 copper vessels from archaeological and museum collections deriving from Spanish colonial contexts were analyzed with a handheld portable X-Ray Fluorescence analyzer (pXRF). Originally developed...
Using PXRF technology to aid in the recovery and analysis of human remains (2015)
Excavation and analysis of human remains from the Milwaukee County Institution Grounds Poor Farm Cemetery (MCIG) provided an opportunity to test the effectiveness of portable X-ray fluorescence (pXRF) as both a field and laboratory tool. During the fieldwork portion of the project, excavations exposed soils that visual inspection suggested might harbor a concentration of toxic materials. PXRF was used on site to determine the nature of the potential toxins and determine the risk factor...
Using pXRF to test for the market exchange of obsidian at Postclassic Santa Rita Corozal, Belize. (2016)
This poster discusses the levels of access to various obsidian sources and source regions as a prerequisite to testing a market exchange model for the distribution of obsidian during the Postclassic period (A.D 1150 - 1530) at Santa Rita Corozal, Belize. A sample of 247 obsidian artifacts dating to the Postclassic period were assayed using portable X-ray fluorescence spectrometry (pXRF) to determine the obsidian sources being exploited. Five sources were identified in the assemblage, including...
VAFB-2019-08: Vandenberg Air Force Base Fiscal Year 2018 Vandenberg Rock Art Monitoring, Contract No. GS10F0059N (2019)
This report documents and outlines the condition assessment of each rock art site on Vandenberg Air Force Base (VAFB) for Fiscal Year 2018 (FY18). This report lists information about each site and brief summaries about common impacts, tasks, and specific observations at sites. Information in this report focuses on areas at rock art sites with significant impacts, high-risk areas for impacts, and professional insight to help understand the sensitivity of sites and implemented management...
Weapons Of Ebenezer, Georgia In The American Revolution (2023)
This is an abstract from the session entitled "The Archaeology of Arms: New Analytical Approaches", at the 2023 annual meeting of the Society for Historical Archaeology. During the American Revolution, the town of New Ebenezer, Georgia alternated between British and Patriot headquarters. In 1779 British forces built seven redoubts surrounding the town. In 1782, Continentals entered Ebenezer and began to reclaim Georgia. Archaeologists have studied eight military locations in addition to other...
When Trash Becomes Treasure: A Postclassic Maya Obsidian Core Cache from Nojpeten (2014)
This paper examines an obsidian cache offering excavated near the corner of a Postclassic Maya platform structure in Nojpeten, on the island of Flores, Guatemala. The cache consists of approximately 190 obsidian prismatic blade cores and core fragments, but the original number of cores placed in the cache likely fell between 173 and 182, with a best estimate of 177, 178, or 180. The cores were found about 20 cm southwest of the structure in a circular concentration measuring approximately 35 cm...
Working toward a Lost Cause? Comparing Handheld XRF Analysis to Neutron Activation Analysis and Petrography Using Maya Ceramics from Holtun, Guatemala (2021)
This is an abstract from the "SAA 2021: General Sessions" session, at the 86th annual meeting of the Society for American Archaeology. Recent research has demonstrated that Handheld (portable) X-ray fluorescence spectrometers (pXRF) have difficulty in consistently and accurately determining chemical composition of non-homogenous cultural materials such as ceramics. This is unfortunate as pXRF instruments have proven to produce accurate and consistent compositional data for other...
