La Ferrería is an archaeological site located in the Mexican state of Durango, north of the country. This settlement has been thought as the product of the interaction of three different pre-Hispanic traditions: Chalchihuites culture, Aztatlán tradition and a local culture known as Loma San Gabriel. Along various systematic excavations in the site, 77 obsidian artefacts were collected, containing flakes, blades and projectile points. Since the origin of the raw material and the cultural affiliations of these artefacts were unknown, a non-destructive portable XRF analysis and an innovative statistical procedure was applied to classify them and determine their provenance, resulting in the detection of four chemically differentiated sources. The provenance study shows that the inhabitants of the site acquired most of their raw material from Llano Grande, the geological deposit closest to the site. However, the detection of obsidian utilization from other regions suggests some type of interaction between the pre-Hispanic cultures of northwest Mexico, including Sonora region.

La Ferrería 是一个考古遗址，位于墨西哥北部杜兰戈州。这个定居点被认为是三种不同的前西班牙裔传统相互作用的产物：Chalchihuites 文化、Aztatlán 传统和被称为 Loma San Gabriel 的当地文化。沿着该遗址的各种系统挖掘，收集了 77 件黑曜石文物，包括薄片、刀片和射弹点。由于这些文物的原材料来源和文化归属未知，因此采用无损便携式 XRF 分析和创新的统计程序对它们进行分类并确定其来源，从而检测到四种化学差异来源。出处研究表明，该地点的居民从距该地点最近的地质矿床 Llano Grande 获得大部分原材料。然而，从其他地区检测到的黑曜石利用表明墨西哥西北部包括索诺拉地区在内的前西班牙文化之间存在某种类型的相互作用。
