En este trabajo se analiza la iconografía de dos cilindros efigie duplicados mayas hallados en cuevas y abrigos rocosos de Laguna Pethá, municipio de Ocosingo, Chiapas. A través de un análisis comparativo nosotros tentativamente identificamos un nuevo estilo regional maya asociado a la presencia de aletas en cilindros de cerámica vinculados a Toniná en el valle de Ocosingo. Sus características iconográficas sitúan a estas piezas próximas al periodo Posclásico Tardío y el Colonial Temprano. Adicionalmente, la aplicación de arqueometría —específicamente de Espectrometría de Masas con Plasma Acoplado Inductivamente (emp ai) y Activación Neutrónica Instrumental (ani)— indican que los dos cilindros fueron hechos al mismo tiempo y con la misma arcilla. Los resultados demuestran su autenticidad y su posible producción local por manos de un mismo artesano o taller cerámico en Laguna Pethá o cerca del valle de Ocosingo. 

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.

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.
