The Chaves cave (Huesca, Spain) is located in the central Pre‐Pyrenean range in NE Iberia. It is a huge cave opening to the east, which was systematically excavated between 1975 and 2007. Several human occupations from the Upper Palaeolithic and the Neolithic periods were documented. Archaeological investigations had barely covered a tenth of the total area when they were abruptly interrupted by the destruction in 2007 of most of the archaeological sediments and all the preserved Neolithic levels that had not yet been excavated. While the most intensive prehistoric occupations of the cave were Neolithic, several components from the Upper Palaeolithic were also detected and excavated before 2007. The recovered lithic tools, as well as the radiocarbon dates, revealed that the Chaves cave was frequented by hunter–gatherer groups during the Upper Solutrean and the Upper Magdalenian. Lithic raw materials from the Palaeolithic levels are diverse, with several chert types identified. The recovered lithic set was subjected to micropaleontological, petrographic and geochemical analyses (energy‐dispersive X‐ray Fluorescence and laser ablation inductively coupled plasma mass spectrometry). The results revealed several origins for the chert, not only from the southern Pyrenees but also from the northern versant, demonstrating that this mountain range was regularly crossed during the Upper Palaeolithic.

Chaves洞穴（西班牙韦斯卡省）的岩性原材料采购：定义旧石器时代人类活动性的地球化学方法

Chaves洞穴（西班牙韦斯卡省）位于伊比利亚东北部中比利牛斯山脉中部。它是东方的一个巨大洞穴，于1975年至2007年间进行了有系统的挖掘。据记载，上石器时代和新石器时代曾发生过几次人类占领。考古调查几乎覆盖了整个地区的十分之一，因为它们在2007年遭到大部分考古沉积物的破坏和所有尚未发掘的新石器时代遗址的破坏而突然中断。虽然该洞穴的史前时期最密集的占领是新石器时代的，但在2007年之前也发现并挖掘了旧石器时代上的一些成分。回收的石器工具以及放射性碳年代，揭示了查韦斯洞穴是在南部Solutrean和上马格达利安时期经常被狩猎者和采集者聚集的地方。来自旧石器时代的岩性原材料种类繁多，已鉴定出几种石类型。回收的石器组接受了微古生物学，岩石学和地球化学分析（能量分散X射线荧光和激光烧蚀电感耦合等离子体质谱法）。结果表明，不仅有南比利牛斯山脉，而且有北北部的多桑树，才有数个the石起源，这表明该山脉在旧石器时代的上段定期穿越。岩石学和地球化学分析（能量色散X射线荧光和激光烧蚀电感耦合等离子体质谱法）。结果表明，不仅有南比利牛斯山脉，而且有北北部的多桑树，才有数个the石起源，这表明该山脉在旧石器时代的上段定期穿越。岩石学和地球化学分析（能量色散X射线荧光和激光烧蚀电感耦合等离子体质谱法）。结果表明，不仅有南比利牛斯山脉，而且有北北部的多桑树，才有数个the石起源，这表明该山脉在旧石器时代的上段定期穿越。
