THE RESULTS OF PHYSICAL AND CHEMICAL INVESTIGATIONS OF THE NEOLITHIC CERAMICS OF THE BOGORODSKOYE-24 SETTLEMENT (Lower Priamurye)
The article presents the results of physical and chemical investigations of the Neolithic ceramics of the Bogorodskoye-24 settlement (Ulchsky district of the Khabarovsk Krai), held by the Russian-Japanese expedition in 2008. Using the methods of petrography, radiography and thermogravimetry, the authors studied the fragments of Malyshevo culture ceramics of the middle and the “post-malogavan” type of the Neolithic final stages. The results of the petrographic analysis showed that the use of mineralogical-chamotte type of molding masses dominated in Malyshevo complex, the use of mineralogenic-organogenic and mineralogen-icchamotte-organogenic type dominated in the post-malogavan complex. All samples contained the same set of mineral phases: quartz and feldspars (plagioclases). The thermogravimetry analysis showed that the fragments of Malyshevo ceramics could be divided into two groups. The results of physicochemical analysis of the ceramics from the Bogorodskoye-24 settlement was compared with the previously obtained results of the same ceramics from the Suchu settlement. The main conclusion that can be stated from the analysis of the Malyshevo ceramics from Bogorodskoye-24 settlement is that it showed the signs of the incomplete pottery tradition; “post-malogavan” ceramics showed that there could be a mixture of different pottery traditions.
