“…It is also a picture that has often been based around the site as the primary unit of analysis, when most sites have long periods of occupation and potential variation in specific phases and sub-contexts (already implicit in the phasing in the tables in . Now, however, advances in analytical techniques (e.g., Poupeau et al, 2007;Carter, 2014;Forster and Grave, 2012;Frahm, 2013) make it increasingly feasible to provenance many artefacts from single assemblages (or even entire assemblages) and to link techno-morphological attributes to provenance data in a way that has hitherto not been possible (e.g., Maeda, 2013;Carter et al, 2014;Milić, 2014;Campbell and Healey, 2016). This starts to change our approach to understanding obsidian use in the past.…”

The presence of obsidian in the Near East has always evoked a response about its exotic nature and origins. It was not until 1960s, however, that this was put onto a scientific footing when Colin Renfrew and his collaborators began to explore obsidian in Turkey and the Mediterranean. Their characterisation of the sources allowed them to attribute artefacts to different sources and suggest models of dispersal and distribution. Since then considerably more artefacts have been attributed to sources, although mostly only small numbers from individual sites; this has led to various interpretations of how obsidian was obtained and used; new studies have considered least cost path analysis, network analysis and agent based modelling. Increasingly, new methods of provenancing of artefacts have also meant that large number of artefacts can be analysed relatively speedily and efficiently. Portable instruments allow data to be collected outside laboratories, avoiding restrictions imposed by export licenses or simplifying work on museum collections. Here we employ richness and diversity indexes to elucidate some of the patterns in obsidian source use and argue that there are several reasons why the provenancing of large proportions of assemblages will be critical in exploiting the true potential of obsidian studies in the Near East, even though the initial haphazard, small sample approach has been quite effective in sketching out the big picture.

This paper presents an overview of the work conducted by our research group in the Mediterranean area. Initiated in the 1990s by the late Gérard Poupeau, our research relies on international and multidisciplinary collaborations to endeavour archaeological and anthropological issues linked to the diffusion and consumption of the obsidian raw material during the Neolithic period. Our line of action is to develop flexibly unique analytical strategies, tailored to each obsidian assemblage considered for a sourcing study. Drawing its strength from the complementarity of the methods available within our group, i.e. visual characterisation, SEM-EDS, ED-XRF, pXRF, PIXE, and LA-ICP-MS, this approach allows for the exhaustive and non-destructive analysis of those assemblages, thus optimising the potential of sourcing studies. Working hand in hand with archaeologists, the results are closely integrated to the information brought by the typological and technological characteristics of the artefacts, in the aim to reconstruct an overview of the obsidian economy at site level, but also to replace it in a broader — regional and supra-regional — context

“…Enfim, dois últimos obstáculos se opõem a uma utilização predominante da datação TF em pesquisas futuras de proveniência, quais sejam: a exigência em materiais e o tempo das medições, frequentemente proibitivos. De fato, a caracterização de uma obsidiana por traços requer duas plaquetas da ordem de 3x3x2 mm 3 , o que o torna um dos métodos mais consumidores em volume de amostra dentre o conjunto de métodos ditos destrutivos (Poupeau et al, 2007). Por fim, o tempo de aquisição dos dados, as medidas das densidades e dos diâmetros dos traços frequentemente é maior, podendo facilmente ultrapassar um dia inteiro para apenas uma obsidiana.…”

A datação por traços de fissão aplicada em estudos do Plio-Quaternário é pouco conhecida no Brasil. O objetivo principal do presente manuscrito, redigido em língua portuguesa, é apresentar e fazer ampla divulgação das potencialidades desta metodologia aos pesquisadores que atuam nesse domínio temporal das ciências da natureza no nosso país. Para tal são apresentados detalhadamente todos os aspectos da datação por Traços de Fissão. São abordados os princípios básicos da datação por Traços de Fissão, a equação da idade, precisão e acurácia, as técnicas analíticas utilizadas em função das particularidades e natureza dos materiais, suas limitações assim como os casos de sucesso. Também são apresentados diversos estudos de caso com exemplos de utilização da metodologia nas variadas áreas de aplicação de pesquisas do Plio-Quaternário, inclusive em arqueologia.
