解决考古黑曜石中的源间歧视问题是地质考古学调查中反复出现的问题，特别是因为在过去几十年中，世界范围内已知的考古黑曜石来源数量几乎呈指数级增长，考古问题的复杂性也同样增长。这两个平行的考古调查方面需要更精确地了解来源之间的地质关系，并更准确地分析这些来源的考古黑曜石。这在北美西南部尤其如此，那里的考古调查频率是世界上最高的，用于解释该记录的理论和方法变得越来越微妙。在这里，我们试图解开考古黑曜石的元素相似性在莫戈隆达蒂尔火山省西南部的新墨西哥州，其中一些最重要的和广泛分布的源位于和源之间的元素相似性是巨大的，即使源之间的距离很大。结合元素，同位素和地质年代学分析作为一个密集的试点研究，我们解开这种复杂性，以提供更好的了解这些重要的考古黑曜石来源。
Solving issues of intersource discrimination in archaeological obsidian is a recurring problem in geoarchaeological investigation, particularly since the number of known sources of archaeological obsidian worldwide has grown nearly exponentially in the last few decades, and the complexity of archaeological questions asked has grown equally so. These two parallel aspects of archaeological investigation have required more exacting understanding of the geological relationship between sources and the more accurate analysis of these sources of archaeological obsidian. This is particularly the case in the North American Southwest where the frequency of archaeological investigation is some of the highest in the world, and the theory and method used to interpret that record has become increasingly nuanced. Here, we attempt to unravel the elemental similarity of archaeological obsidian in the Mogollon‐Datil volcanic province of southwestern New Mexico where some of the most important and extensively distributed sources are located and the elemental similarity between the sources is great even though the distance between the sources is large. Uniting elemental, isotopic, and geochronological analyses as an intensive pilot study, we unpack this complexity to provide greater understanding of these important sources of archaeological obsidian.
