ABSTRACT

The lithic operational chains at the Mesolithic site of La Uña (León, N Spain) have been analysed and reconstructed through a joint study of the raw material provenance and technological characteristics of the assemblage. Differences in the management of each raw material have been observed, and three degrees of integrity of the chaîne opératoire (complete, incomplete and broken) have been differentiated. In addition, two main production targets have been identified: flakes and laminar blanks. Specific operational chains were followed to obtain each one. Differences between the raw materials have also been observed in the main production of blanks, with four groups: exclusively flakes, exclusively blade/bladelets, mixed with preference for blade/bladelets and mixed with preference for flakes.

摘要

通过对组合的原材料来源和技术特征的联合研究，分析和重建了 La Uña（莱昂，西班牙北部）中石器时代遗址的石器操作链。观察到每种原材料的管理差异，并区分了 chaîne opératoire 的三个完整程度（完整、不完整和破碎）。此外，还确定了两个主要生产目标：薄片和层状坯料。遵循特定的操作链来获得每一个。在坯料的主要生产中也观察到原材料之间的差异，有四组：完全薄片、完全刀片/刀片、混合偏好刀片/刀片和混合偏好薄片。
