Stratigraphic and planigraphic context of Early Upper Paleolithic assemblages from Ust'-Karakol-1 site (excavation of 1993-1997)

This paper summarizes results of the stratigraphic and planigraphic analyses of Early Upper Paleolithic assemblages deposition from Ust'-Karakol-1 site (Russian Altai, Anui river valley) based on results of 1993-1997 excavation seasons. Main research focus is aimed to the reconstruction of distribution of lithic artifacts according to petrographic units basing on refitting and petrographic studies. This approach allows to re-evaluate the post-depositional taphonomy of artifacts and raises questions about their affinities to the previously established «cultural layers».
