New data on stratigraphic context of sedimentation materials of the Late Neolithic in the Lower Tom Region

The Neolithic in the Lower Tom region has been studied for more than half a century. During this time, a significant number of sources has been accumulated. Some ofthem were obtained during excavations in the first half and mid-20th century, while the other part is represented by random finds. At present, natural landscapes have changed due to the development of the city and urbanization of the surrounding area. Therefore, the search for the sites of this time under old paradigms has become difficult, and modeling the occurrence context of existing random finds is completely impossible. To solve these problems, a comparison was made of the stratigraphic context of occurrence of artifacts from the archival materials from excavations of the Late Neolithic burials at the burial ground near the Old Muslim Cemetery and stratigraphic profiles obtained during modern surveys in the areas ofTomsk being closest to it. As a result, it was established that the cultural layer of the Late Neolithic site, the closest to the described burial ground, lies in the same sediments as the items from the accompanying inventory located near the edges of the Neolithic burials. This indicates the chronological comparability of the two objects, and allows us to define the sediments containing the cultural remains of the Late Neolithic period as a layer of light-brown or gray-brown sandy loam with the layers of brown loam. Taking into account the available natural science data on the reconstructed climatic environment in the Late Neolithic, these sediments were formed in warm and dry conditions of the subboreal period of the Holocene. The obtained results are used to search for the sites of the period under study located on the terraces of the Tom River in its lower reaches. Further, they can be used for predictive modeling of the occurrence context of accidentally discovered artifacts.
