This paper reports the results of a recent geological and archaeological survey conducted in the Sarab district (Sabalan area) in Northwestern Iran. This survey aimed to identify potential obsidian outcrops in the region and to investigate archaeological sites in the vicinity to assess their obsidian exploitation patterns. We located a new obsidian source, Ideloo, and surveyed the previously known archaeological sites of Tepe Qalehjoogh, Kultepe Asbfrooshan, Tepe Emam Chay and Qaleh Tepe Abarghan. Here, we describe the methods and results of our surveys, along with the geochemical characterisation, using portable XRF and LA‐ICP‐MS, of both the new outcrop and the obsidian artefacts found on the sites. Our analyses have revealed the consumption of Ideloo obsidian on three of the four sites surveyed, confirming its exploitation by local communities. While validating previous assumptions regarding the existence of potential obsidian sources in Northwestern Iran, our study also highlights the consumption of raw materials originating from the Caucasus or Eastern Anatolia in complement to local resources. However, the diffusion of the Ideloo obsidian seems so far restricted to a small area, which suggests more complex consumption and trade patterns than previously expected.

消费本地：Ideloo（伊朗西北部）的新黑曜石来源，以及邻近史前社区使用的第一个证据

本文报告了最近在伊朗西北部的Sarab地区（Sabalan地区）进行的地质和考古调查的结果。这项调查旨在确定该地区潜在的黑曜石露头，并调查附近的考古遗址，以评估其黑曜石开采方式。我们找到了一个新的黑曜石来源Ideloo，并调查了Tepe Qalehjoogh，Kultepe Asbfrooshan，Tepe Emam Chay和Qaleh Tepe Abarghan以前已知的考古遗址。在这里，我们描述了调查的方法和结果，以及使用便携式XRF和LA‐ICP‐MS对新发现的露头和黑曜石文物进行地球化学表征的过程。我们的分析表明，被调查的四个地点中有三个地点食用了Ideloo黑曜石，证实了当地居民对其的开采。在验证先前关于伊朗西北部存在黑曜石潜在来源的假设时，我们的研究还强调了消耗高加索或安纳托利亚东部地区的原材料以补充当地资源。但是，到目前为止，爱德鲁黑曜石的扩散似乎仅限于一小块区域，这表明消费和贸易方式比以前预期的更为复杂。
