Fuente del Trucho cave (Asque‐Colungo, Huesca, Spain) is located in the central Pre‐Pyrenean range in north‐east Iberia, in the Arpán ravine, a tributary of the Vero River. The mouth of the cave is 22 m wide and it is oriented to the south‐east. The entrance gives access to a 24 m‐deep hall. Palaeolithic paintings were discovered in the cave in 1978. The Fuente del Trucho art comprises two sectors: the external with some engraved motifs and the internal featuring more than 100 painted motifs distributed in 21 panels. Archaeological works have been undertaken since 1979, identifying several human occupations from the Middle and Upper Palaeolithic. This paper presents results obtained after the analysis of lithic raw materials. The analyses were performed using the classical archaeopetrological approach, which comprises textural, micropalaeontological and petrographical analyses, combined with the application of geochemical methods, using energy‐dispersive X‐ray fluorescence (ED‐XRF) and laser ablation inductively coupled plasma mass spectrometry (LA‐ICP‐MS). The results show that chert and quartzites were the most commonly used rocks. Different types and origins of chert were identified, demonstrating the existence of a wide mobility for lithic raw material procurement during all the Palaeolithic occupations.

表征来自Fuente del Trucho（韦斯卡省Asque-Colungo）的石器原材料：关于伊比利亚东北部旧石器人类活动的新数据

Fuente del Trucho洞穴（西班牙韦斯卡省，阿斯奎·科伦戈）位于维罗河的支流阿潘河谷中，伊比利亚东北部中比利牛斯山脉中部。洞口宽22 m，面向东南。入口可通往24 m深的大厅。1978年在山洞中发现了旧石器时代的绘画。丰特·德·特鲁乔艺术分为两个部分：外部带有一些雕刻图案，内部具有分布在21个面板中的100多个绘画图案。自1979年以来就进行了考古工作，确定了旧石器时代中期和中期的几个人类职业。本文介绍了在对片状原材料进行分析后获得的结果。使用经典的考古岩石学方法进行分析，包括构造，微观古生物学和岩石学分析，结合地球化学方法的应用，使用能量分散X射线荧光（ED-XRF）和激光烧蚀电感耦合等离子体质谱法（LA-ICP-MS）。结果表明，硅质岩和石英岩是最常用的岩石。确定了不同类型和来源的of石，这表明在所有旧石器时代的职业中，广泛存在着用于石料原料采购的流动性。
