摘要：Lithic reduction sequences are a fundamental topic in palaeolithic research, since they provide data on the behavioural capabilities of early hominids. This paper studies the variability of lithic reduction strategies in the Abric Romaní (Capellades, Barcelona). This site has an extensive stratigraphic sequence, dated between 40 and 70 ka BP. In this sequence, mostly formed by travertine deposits, 27 archaeological levels have been identified, most of them corresponding to the Middle Palaeolithic. The Middle Palaeolithic levels so far excavated (B-L) are dated between 40 and 52 ka BP, and suggest a reconstruction of the behavioural patterns of the Neanderthal groups preceding the early Upper Palaeolithic. The variability of the reduction sequences in a synchronous level and the changes over time are presented in the framework of the operative field concept. The results suggest that the technological changes in the Middle Palaeolithic can be explained by technical criteria that are reflected in different domains of analysis; these criteria are related to the degree of technical knowledge invested in lithic production and the range of technical options envisaged in each archaeological level.
