摘要

The Epigravettian of Santa Maria d'Agnano site is represented by a SMA-Extern layer (SU4). The present study resorts to a micromorphological analysis to clarify the depositional and the post-depositional process of the open air site in front of the Santa Maria d'Agnano cave. Epigravettian samples from the open air level (SU4), spanning from 18013-17587 CalBC to 9752-9298 CalBC are analysed. Results show a complex microstructure due to the combination of the pedological deposition mode and the anthropogenic input. Variable amounts of centimetric sub-angular limestone confirm the deposition from the roof fall. Bone,charcoal fragments and micro-artefacts are present throughout the micromorphological column and are considered as indicators of human activity. The groundmass contains ferruginous pedofeatures such as nodules, mottles and coatings. The latter are derived from a local degraded soil in the immediate surroundings or may be formed in situ. Locally, spar and microspar were precipitated inside voids. Such features can probably be formed by the reprecipitation of carbonates after a partial dissolution of cryoclasts. These thin sections provide little evidence for anthropogenic input and a general event that includes soil phases.The study of the lithic industry confirms the existence of a chronostratigraphy that spreads over a period of seven thousand years. In this culturally homogeneous context some changes can be noticed thanks to the more or less frequent presence of some tools. The background appears Epigravettian, since it is characterized throughout the chrono-sequence by the recurring presence of straight back points, Gravette type.
