Recent archaeological research has highlighted the potential role of mobile pastoral groups in the diffusion of raw materials and technological innovations between the southern Caucasus and north-western Iran from the Neolithic onwards. Two successive projects, PAST-OBS and SCOPE, were designed to explore this hypothesis through the study of obsidian consumption patterns from the Neolithic to the Bronze Age using a flexible analytical strategy that considerably extends the scale of obsidian studies in these regions. By focusing on the exploitation of obsidian at multiple levels—local, regional and interregional—we hope to unravel the complexity of the obsidian networks under study. The aim of this paper is to present (1) a reassessment of the work so far carried out by previous obsidian studies, with a view to homogenizing and to clarifying the nomenclature in use; and (2) an introduction to the PAST-OBS and SCOPE projects in order to initiate a discussion of our preliminary results.

扩大黑曜石研究的规模：对南高加索和伊朗西北部黑曜石史前环流模式的高分辨率调查

最近的考古研究强调了流动牧区在从新石器时代开始在高加索南部和伊朗西北部之间传播原材料和技术创新方面的潜在作用。两个连续的项目，PAST-OBS 和 SCOPE，旨在通过使用灵活的分析策略研究从新石器时代到青铜器时代的黑曜石消费模式来探索这一假设，该策略大大扩展了这些地区的黑曜石研究规模。通过在本地、区域和跨区域等多个层面关注黑曜石的开发，我们希望解开所研究的黑曜石网络的复杂性。本文的目的是展示 (1) 对迄今为止黑曜石研究迄今为止所做工作的重新评估，为了统一和澄清使用中的命名法；(2) 介绍 PAST-OBS 和 SCOPE 项目，以启动对我们初步结果的讨论。
