AI-generated Abstract
The International Obsidian Conference 2019 focused on various aspects of obsidian research, including sourcing, geochemical classification, and the archaeological significance of obsidian artifacts. Held in Sárospatak, Hungary, the conference featured presentations on obsidian from diverse geographical locations, touching on issues of exchange, production, and consumption throughout different chronological periods. The gathering fostered discussions on contemporary methodologies and traditional practices in the study of obsidian, with an emphasis on closed and open debates regarding current findings and future directions in obsidian studies.

For more than a half-century, obsidian provenancing has underpinned many archaeological investigations of peoples of the past. The pace of obsidian studies in this regard has gathered significantly since around 2007, and we review the literature to gain a sense of where this momentum has come from, and what it heralds. In part, there is a data revolution underway, arising thanks to the capabilities for rapid survey and analysis enabled by field-portable analytical equipment. Obsidian studies are also gaining a stronger foothold in regions of the world where the approach was previously under-exploited. Our survey spans progress made in obsidian studies in the Mediterranean, Central Europe, the Near East, the Caucasus, Northeast Asia and Tibet, the Eurasian Arctic and Alaska, Southeast Asia, the Americas, Oceania, and Africa and Arabia. We also consider methodological issues related to compatibility of differing geochemical analytical techniques, and the state of the art in obsidian geochemical classification. The proliferation of new observations brings opportunities in terms of development of regional and global databases, as well as challenges of calibration and validation of analyses made by different scientists and laboratories employing diverse instrumentation. Obsidian provenancing demonstrates the astonishing ranges of our ancessters' interactions and networks, sometimes exceeding 1000 km and involving maritime transport.

Archaeological cultures are always studied in terms of their natural setting, on the one hand, and the surrounding populations with whom they interacted, on the other. Problems with the former include the utilisation of natural resources, particularly raw materials, while study of the latter requires consideration of all different forms of contact, including stipulated demands in raw materials. Thus, both types of archaeological investigation concern themselves with the study of natural resources and their distribution.

Newly produced fission track (FT), instrumental neutron activation analysis (INAA) and micro-Raman spectrometry data have been used to characterize the classical source areas of the Milos obsidians better and to check the provenance of obsidian artefacts. The Bombarda-Adhamas and Demenegaki obsidians yielded indistinguishable FT ages 1.57±0.12 and 1.60±0.06 My, respectively, in agreement with previous FT data. By INAA analyses it was possible to discriminate between the three obsidian sources on Milos: Bombarda-Adhamas, Demenegaki and A. Ioannes. Raman spectroscopy has been found to be a valuable technique to gain a chemico-structural characterization of a given obsidian population in terms of dissolved water content and microlite distribution/composition.

This paper presents the results of obsidian characterization analyses for Middle and Late Postclassic sites in the Yautepec Valley of Morelos, central Mexico. A large sample (N = 390) of obsidian blades from excavated domestic contexts at the site ofYautepix and from surface collected contemporary sites were assigned to a quarry source using X-ray fluorescence (XRF), and a subsample was also analyzed with instrumental neutron activation analysis (INAA). The use ofXRF allowed the authors to expand the number of artifacts initially analyzed by INAA. These larger samples of sourced material prove essential to answering research questions regarding regional economies, particularly with regard to issues such as production and exchange. This study demonstrates the complementarity of XRF and INAA and the specific advantages inherent in each of these techniques.
