Abstract The integrity of the different levels that form a sequence and the formation processes of the archaeological deposit must be assessed as a previous step to the construction of behavioural, cultural and evolutionary interpretations. This is especially relevant when dealing with long sequences and cultural evolution constructed on them, as is the case in the research on Upper Palaeolithic. Lithic taphonomy provides insight into these issues and refitting is one of its powerful tools. This approach has been applied to the Aurignacian, Gravettian and Solutrean levels of Cova de les Cendres (Teulada-Moraira, Alicante, Spain), where fracture refits of laminar fragments –including blades, bladelets, and laminar flakes– have been systematically searched. The 29 found refits are quantitatively analysed, with special attention to the type of fracture and the differences of the dimensions of the pieces. Spatial analysis is carried out to evaluate the horizontal and vertical distribution of the connections and their distances. The results reveal a low presence of inter-level conjoins and a minority of long vertical displacements, which is interpreted as evidence of a certain degree of integrity of the stratigraphic sequence.

改造岩屑层流碎片以评估旧石器时代序列：Cova de les Cendres（Teulada-Moraira，阿利坎特，西班牙）的案例

摘要 形成序列的不同层次的完整性和考古矿床的形成过程必须作为构建行为、文化和进化解释的前一步进行评估。这在处理基于它们构建的长序列和文化进化时尤其重要，例如旧石器时代晚期的研究。石器填埋术提供了对这些问题的洞察力，改装是其强大的工具之一。这种方法已应用于 Cova de les Cendres（Teulada-Moraira，阿利坎特，西班牙）的 Aurignacian、Gravettian 和 Solutrean 水平，其中层流碎片的断裂改造——包括叶片、小叶和层流薄片——已被系统地搜索。对发现的 29 个改装进行了定量分析，特别注意断裂的类型和碎片尺寸的差异。进行空间分析以评估连接的水平和垂直分布及其距离。结果表明，层间连体的存在率较低，并且存在少量长垂向位移，这被解释为地层层序具有一定程度完整性的证据。
