Within the framework of archaeological palimpsest dissection, stratigraphic association of lithic remains with hearths and other archaeological materials in undisturbed Neanderthal contexts allows us to seek patterns in lithic and faunal assemblage composition, assess the degree of time averaging within assemblages and investigate the spatial distribution of archaeological remains. So far, the European Neanderthal record shows variability in such spatial parameters, not only among different geographic regions but also across time. This approach has been employed to draw conclusions about the main features of Neanderthal occupations from in situ archaeological contexts within individual site sequences. As contribution to this topic, we present new results from our ongoing archaeostratigraphic investigation of stratigraphic unit xa from El Salt (Alcoi, Alacant, eastern Iberia). Our previous study, based on stratigraphic analysis of the lithic record consisting of raw material units, yielded several micropalimpsests within unit xa. Here, we carry out further technological and spatial analysis of the micropalimpsest units. The results obtained from it suggest that we may be able, in specific cases, to recognise indicators of diachrony within the context of these archaeostratigraphic units. This confirms the existence of a micropalimpsest, and suggests that we have the chance to find analytical frames that are even closer to the human temporal scale than the AU. This should be the target of future interdisciplinary behavioural study of El Salt unit xa. This work illustrates the potential of a spatial and archaeostratigraphic approach to stone tool technology and brings to light the importance of archaeological palimpsest dissection as a first step for behavioural analysis in Palaeolithic research.

关于识别旧石器时代的单一占领事件：El Salt地层单位xa的尼安德特人石器记录的考古地层学和技术方法（伊比利亚东部的Alcoi）

在考古最简单的解剖框架内，在不受干扰的尼安德特人语境下，石器遗迹与炉床和其他考古材料的地层学联系使我们能够寻找石器和动物群组成的模式，评估集合内平均时间的长短，并研究考古空间的分布遗迹。到目前为止，欧洲尼安德特人的记录显示出这种空间参数的可变性，不仅在不同的地理区域之间，而且在整个时间上都是如此。该方法已被用来得出关于尼安德特人职业主要特征的结论，这些特征来自各个地点序列中的原地考古环境。作为对此主题的贡献，我们提出了正在进行的地层单位考古地层调查的新结果x a来自El Salt（Alcoi，Alacant，伊比利亚东部）。我们之前的研究基于对由原材料单元组成的岩性记录的地层分析，得出了在单元x a内出现的几个微晕现象。在这里，我们对微型palestsest单元进行进一步的技术和空间分析。从中获得的结果表明，在某些情况下，我们也许能够在这些古地层单位的背景下识别历时指标。这证实了最微弱的存在，并表明我们有机会找到比AU更接近人类时间尺度的分析框架。这应该是El Salt单位x未来跨学科行为研究的目标一种。这项工作说明了空间和考古地层方法在石材工具技术中的潜力，并阐明了考古上最清扫的重要性，这是旧石器时代行为分析的第一步。
