Palimpsests are ubiquitous in the open-air archaeological record. Yet, integrated intra-site research strategies of palimpsest dissection to infer occupational histories, spatial behavioral patterns and site formation processes remain very exeptional in the Postglacial archaeology. In this work, we introduce a novel and integrated analytical framework of palimpsest dissection applied to the lithic assemblages of the Unit IV of El Arenal de la Virgen site, radiocarbon dated in two different occupation phases (9.3-9.1 k and 8.6-8.3 k cal BP). While our archaeostratigraphic analysis identified the absence of sterile layers between both phases, the lithic refits confirmed the good preservation of the spatial properties of the assemblage. Using different point-pattern analysis and geostatistical techniques, we further investigate the overall distribution pattern, the spatial correlation between lithic remains and occupation features according to different artifact categories, and the variability of spatial autocorrelation metrics. Our results show significant differences between both occupation phases: a lithic cache and few short-distance connections during the Phase 1; and a much more extensive occupation during the Phase 2, with hearth-related assemblages, a dwelling area and latent combustion loci (not identified during the excavation process) affected by trampling. Finally, we discuss the site struture and spatio-temporal dimesions of the lithic assemblages to conclude a behavioural pattern of different, and spatially recurrent, short-term camp occupation episodes. Built on explicit quantitative and reproducible standards, our research approach can be applied to other open-air sites to conduct comparative studies on open-air occupation patterns.
