专著《L‘obsidienne au Proche et Moyen Orient：Du VolcanàL’outil》(考文等人，1998年)首次出版于25年前，在其封面之间，Poidevn(1998年)一章概述了位于现在土耳其西部、中部和东部以及高加索地区的黑麻岩来源的地球化学和地质年代学数据。这一章在当时是一个非常有价值的资源。然而，修订是早就应该进行的，这是我努力提供更新的两篇文章(参见Frahm，2023)中的第二篇。在这里，我重点介绍从南爱琴海火山弧的希腊岛屿到土耳其中部的中安纳托利亚火山省的黑铁矿来源。与1990年代相比，现在这些来源的基本数据要多得多。例如，Poidevin(1998年)列出了来自7个不同设施的17个Nenezi Dağ黑岩分析。相比之下，我在这里总结了来自26个不同实验室的359个Nenezi Dağ黑岩的测量结果，使用了各种分析技术。因此，有机会为这些特征良好的黑麻岩来源得出强有力的元素共识值。然而，在我在本文中总结的24个黑铁矿来源中，并不是所有的都得到了很好的研究，仍然有重要的工作要做，特别是在土耳其西部。
The monographL'obsidienne au Proche et Moyen Orient: Du volcan à l'outil(Cauvin et al., 1998) was first published 25 years ago, and between its covers, Poidevn’s (1998) chapter summarized the geochemical and geochronological data for obsidian sources that lie within what is now western, central, and eastern Turkey and the Caucasus. That chapter was a highly valuable resource at the time. A revision, though, is long overdue, and this is the second of two articles (see Frahm, 2023) in which I endeavor to provide an update. Here I focus on the obsidian sources from the Greek islands in the South Aegean Volcanic Arc to the Central Anatolian Volcanic Province in central Turkey. Many more elemental data are available for these sources today than during the 1990s. For example, Poidevin (1998) listed 17 analyses of Nenezi Dağ obsidian from seven different facilities. In contrast, here I summarize 359 measurements of Nenezi Dağ obsidian from 26 different laboratories using a variety of analytical techniques. Consequently, there is an opportunity to derive robust elemental consensus values for such well-characterized obsidian sources. Of the 24 obsidian sources that I summarize in this article, however, not all have been so well studied, and there remains important work to be done, especially in western Turkey.
