  3. Abstract

    We present the first geochemical data of archaeological obsidian for Isla Victoria, Nahuel Huapi National Park in Patagonia. XRF analyses were performed on 15 samples of obsidian-like rocks from the Puerto Tranquilo 1 site. Only five of the artifacts—all of which come from upper levels of the site—correspond to obsidian as a raw material. The provenance analysis indicates the use of obsidian sources located in the Andean Forest area of southern Neuquen Province. Based on these preliminary results, we propose a north–south circulation axis for this raw material. These geographic results are discussed in relation to the information available regionally.

  4. In much of the Western world, collaborative research undertaken by settler archaeologists readily lends itself, at least in part, to a continuation of the colonial project. Yet, against this backdrop, Australia's First Nations’ peoples continue to work with researchers and to drive systemic change in research practice. Community-engaged archaeology, defined here as codeveloped studies of ancestral places (following Schaepe et al. 2017), is directed to improving relationships between Indigenous peoples and archaeologists. Even so, the practice of archaeology with and for nonsettler communities remains underdeveloped with regard to institutional priorities and funding agency bureaucracies. Here, we (Mirarr Traditional Owners, Mirarr employees, and settler archaeologist researchers) reflect on these issues as part of our ongoing research on the ochres and bim (rock art) of the well-known Madjedbebe rockshelter in the Alligator Rivers region, Northern Territory, Australia.

  5. Abstract

    This study describes the petrographic and geochemical characteristics of pottery collected from Mugharat al‐Kahf and WTN02 in Wadi Tanuf, north‐central Oman, to clarify interregional similarities and differences in pottery production techniques and examine the existence of interregional trade in pottery with respect to changes in mobile communities. Potsherds from these sites were characterised using thin‐section petrography and instrumental neutron activation analysis. Results revealed that several clay fabrics and tempers were used during the Wadi Suq period (2000–1600 BCE). A region‐wide similarity exists in pottery‐making techniques in terms of the tempering of specific minerals (Oman ophiolite) used in the Early Iron Age (1300–300 BCE). Geochemical results indicate differences in clay sources between the Wadi Suq period and the Early Iron Age in Wadi Tanuf and the unlikelihood of the interregional trade of domestic pottery.

  6. La producción y el consumo de cerámica con vidrio volcánico alcanzó su punto máximo en las Tierras Bajas Mayas durante elos periodos Clásico Tardío al Terminal. Explicaciones por estas cerámicas varían. Diferencias en el tipo de inclusiones volcánicas y forma indican que la cerámica fue producida en lugares múltiples por grupos diferentes de alfareros. Analizamos cerámica de contextos domésticos en Baking Pot, Belice, utilizando la petrográfia y el análisis por activación de neutrónica (NAA) para documentar la variabilidad y determinar la procedencia. La cerámica se produjo con vidrio volcánica fresca y una arcilla micrítica. Los datos petrográficos y químicos indican la cerámica se produjo localmente en el Valle de Belice. Es probable que la variación se debe tanto a las diferencias de producción como a la alteración post-deposicional. Es fundamental utilizar ambas técnicas analíticas para comprender la producción y la procedencia de las cerámicas en las Tierras Bajas Mayas.
