The Early Bronze Age ceramic collection found into the caves of La Llana and El Toral III in Asturias (Spain) presents common decoration such as that found in the centre of Cantabrian Spain from the same period, which resembles others found in the Ebro Valley and Atlantic Europe. Therefore, the main objective of this study it is to identify the raw material origin and understand the pottery production process during the Early Bronze Age in the Cantabrian region. A methodological approach based on the chemical and mineralogical analysis of vessels and experimentally fired clay samples collected all over the centre of this region was developed. Furthermore, the post‐depositional processes affecting the sherds’ composition was evaluated by employing the rare earth elements as markers. The results showed that the studied assemblage has important similarities with the raw materials of the surrounding area, which supports the hypothesis of a regional mobility.

伊比利亚北部青铜时代早期的陶瓷生产和人类互动

在阿斯图里亚斯（西班牙）的拉拉纳（La Llana）和埃尔托拉尔三世（El Toral III）的洞穴中发现的早期青铜时代陶瓷收藏品具有共同的装饰，例如同一时期在西班牙坎塔布连的中心发现的装饰，与在埃布罗谷和大西洋发现的其他装饰相似欧洲。因此，本研究的主要目的是确定坎塔布连地区早期青铜时代的原材料来源并了解陶器的生产过程。开发了一种方法，该方法基于对容器和整个区域中心收集的实验烧制粘土样品进行化学和矿物学分析。此外，通过使用稀土元素作为标记物来评估沉积后过程对种子组成的影响。
