DOCUMENT Citation Only Rosemary Joyce.

This is an abstract from the "2019 Fryxell Award Symposium: Papers in Honor of M. Steven Shackley" session, at the 84th annual meeting of the Society for American Archaeology. When Steve Shackley informed me that over 90% of obsidian samples from Puerto Escondido, Honduras, that he had analyzed came from an unidentified source, presumably nearby, he started a process of re-education that led me to a place where he may not be comfortable, but that I deeply appreciate. This involves a...

This is an abstract from the "2019 Fryxell Award Symposium: Papers in Honor of M. Steven Shackley" session, at the 84th annual meeting of the Society for American Archaeology. The sourcing of lithic raw material often challenges preconceived notions of the relationships between people, places, and objects for time periods prior to written records. But what of historic obsidian? What can sourcing reveal about the more recent past? This paper presents the case study of a most amazing historical...

This is an abstract from the "2019 Fryxell Award Symposium: Papers in Honor of M. Steven Shackley" session, at the 84th annual meeting of the Society for American Archaeology. In 1983, an advertisement for a Tracor X-ray spectrometer proclaimed that "the world of XRF will never be the same again" thanks to an integrated microcomputer that "takes the confusion out of instrumental analysis." It was an exaggeration that this model offered "mistake-proof" XRF, but the point is that this...

This is an abstract from the "2019 Fryxell Award Symposium: Papers in Honor of M. Steven Shackley" session, at the 84th annual meeting of the Society for American Archaeology. The role of obsidian in Clovis technological organization in the US Southwest and northwestern Mexico is investigated. The distribution and typology of obsidian artifacts from excavated sites as well as surface contexts is reviewed. Projectile points appear to be the principal, and nearly only, tool for which obsidian...

This is an abstract from the "2019 Fryxell Award Symposium: Papers in Honor of M. Steven Shackley" session, at the 84th annual meeting of the Society for American Archaeology. For the Central Mediterranean island of Sardinia, studies have shown that the usage of obsidian from specific subsources changed over time. Human selection may have been based on their accessibility, physical properties of the raw material, and the size and quantity available. In addition, socioeconomic factors, lithic...

This is an abstract from the "2019 Fryxell Award Symposium: Papers in Honor of M. Steven Shackley" session, at the 84th annual meeting of the Society for American Archaeology. Over the past three decades, the Geoarchaeological XRF Lab, founded and directed by Steve Shackley, has defined and established unique chemical fingerprints for nearly all of the obsidian sources used by Native Americans in the pre-Hispanic U.S. Southwest. Sources and sub-source localities can be reliably identified...

This is an abstract from the "2019 Fryxell Award Symposium: Papers in Honor of M. Steven Shackley" session, at the 84th annual meeting of the Society for American Archaeology. In the late 1960s, Heizer and colleagues at UC-Berkeley began to use X-ray fluorescence to measure chemical fingerprints for obsidian artifacts from a number of sites in Mesoamerica. In their study of obsidian artifacts from the Olmec site of La Venta, they found that 93% of the artifacts were explained by five distinct...

This is an abstract from the "2019 Fryxell Award Symposium: Papers in Honor of M. Steven Shackley" session, at the 84th annual meeting of the Society for American Archaeology. Obsidian sourcing is a well-established facet of archaeological practice and has the capacity to address a wide range of relevant archaeological questions. For decades, Professor Steven Shackley has been on the forefront of methodological and theoretical developments in obsidian characterization studies, and his...

This is an abstract from the "2019 Fryxell Award Symposium: Papers in Honor of M. Steven Shackley" session, at the 84th annual meeting of the Society for American Archaeology. Steve Shackley’s wide-reaching research includes X-ray fluorescence analyses of obsidian from East Africa. He and co-authors explored sources of obsidian from sites in Ethiopia, providing data that informed many later studies in a relatively unknown region for obsidian studies. Our work on obsidian from mid-Holocene...

This is an abstract from the "2019 Fryxell Award Symposium: Papers in Honor of M. Steven Shackley" session, at the 84th annual meeting of the Society for American Archaeology. The open science movement is growing in archaeology, and raises fundamental questions about data and who it belongs to. In this talk, we outline a protocol for sharing data on obsidian sources to facilitate replicable research. While in obsidian sourcing a direct calibration is preferable (e.g., measuring source...

This is an abstract from the "2019 Fryxell Award Symposium: Papers in Honor of M. Steven Shackley" session, at the 84th annual meeting of the Society for American Archaeology. Studies of obsidian artifacts from sites across Aotearoa (New Zealand) in the 1960s-80s, were critical to identifying a major decrease in mobility, just prior to the onset of endemic warfare, marked by the construction of thousands of fortifications by the ancestors of Māori. Unfortunately, initial enthusiasm was...

This is an abstract from the "2019 Fryxell Award Symposium: Papers in Honor of M. Steven Shackley" session, at the 84th annual meeting of the Society for American Archaeology. After c. 50 years of research using a diverse range of geochemical techniques, patterns of movement for obsidian in the Pacific region, dating from the Pleistocene up to the historic period, have been documented comprehensively. Although there are eight high quality obsidian sources, by far the largest quantity of...

This is an abstract from the "2019 Fryxell Award Symposium: Papers in Honor of M. Steven Shackley" session, at the 84th annual meeting of the Society for American Archaeology. Over the past 15-20 years, archaeological chemistry has moved largely from centralized laboratories of interdisciplinary expertise to decentralized laboratories where expertise often times is lacking. This shift is most pronounced in the widespread adoption and use of inexpensive, compact, highly portable XRF...

This is an abstract from the "2019 Fryxell Award Symposium: Papers in Honor of M. Steven Shackley" session, at the 84th annual meeting of the Society for American Archaeology. The movement of people, objects, and ideas between the American Southwest/Northwest Mexico (SW/NW) and Mesoamerica is one of the most enduring and debated research topics in American archaeology. Pueblo and Mesoamerican groups prominently used obsidian for hunting, warfare, and ceremony, but is there Mesoamerican...

This is an abstract from the "2019 Fryxell Award Symposium: Papers in Honor of M. Steven Shackley" session, at the 84th annual meeting of the Society for American Archaeology. Our WDXRF sourcing program of geological and archaeological specimens (n=177) from the Society Islands, outlines the dynamics of inter- and intra-archipelago exchange over an 800 year period. Adzes from 21 sources were identified. Those traded in from the Marquesas Islands, an over 1,400 km voyage, are found with low...
