 abstract={Naturally-occuring re-depositional processes are known from caves and other multi-layered sites. They are mainly bio- and cryoturbations that can involve huge masses of sediment. However, the processes are only recognizable at sites with laminated and lithologically diversified sediments. Where lithological differences are weak, the boundaries are blurred or rock rubble and numer¬ous stones occur – the sedimentological features are obscured and post-depositional features are unrecognizable. Such situations are especially frequent in caves. The impact of re-deposition on the mixing of archaeological assemblages may be underestimated. A helpful approach for the recogni¬tion of re-deposition is geochemical fossil provenance analysis. The method is based on the fact that the chemical composition of fossils (e.g. mammalian bones) is determined by nature of the surrounding sediment, shortly after the fossil’s original deposition. This phenomenon may be used to determine the original context of bones whose primary location is uncertain (e.g. poorly documented finds from old research). It also allows the determination of possible natural or artificial re-deposition. The results presented in this paper provide evidence for the extensive re-deposition of animal bone in Biśnik Cave. Such observations may well be relevant to the other Polish caves},
