2017年8~9月,重庆市文化遗产研究院同俄罗斯科学院西伯利亚分院考古学与民族学研究所组成联合考古队,对西伯利亚两处旧石器时代遗址进行考古调查与试掘。通过调查与试掘,在叶尼塞河支流—阿巴坎河流域确认了一处旧石器时代晚期遗址—马特盖奇克遗址,该遗址石制品主要包括石核、石片和石器,原料主要是火山岩、燧石和石英岩。通过阶地比对,初步认为该遗址时代为旧石器时代晚期。另外,对库尔塔克卡缅内洛卡遗址的再次发掘出土了44件石制品,包含石核、石片和石器,原料主要是燧石、石英岩和火山岩。此次发掘进一步充实了该遗址的考古材料,也有利于进一步完善该遗址的考古年代学序列。

In order to have a further understanding of paleolithic sites in Siberia, a joint archaeological team of Chongqing Institute of Cultural Heritage and Institute of Archaeology and Ethnography of the Siberian Branch of the Russian Academy of Sciences was established in 2017. From August to September, two paleolithic sites in the Yenisei river were investigated and excavated, and a new paleolithic site named Matkechik in the valley of the Abakan River was surveyed. Matkechik site (near the village of Matkechik) is located in Abakan city, Republic of Khakassia. The artifacts excavated from the site include pebble cores, flakes and tools. The main raw material of the lithics are volcanics, chert and quartzite. Compared with other sites in the same terrace and similar burial context in the Yenisei River Basin, the age of the Matkechik site should be dated to the late Pleistocene.

Besides, an re-excavation was carried out in Kamennyy Log site, which is located in Kurtak geo-archaeological district. An area of 8 m² was excavated, 44 pieces of artifacts excavated from Cultural Horizon 1 and a piece of stone artifacts was excavated from the profile surface of Cultural Horizon 2. The stone assemblage includes flak cores, flakes, chips and retouched tools, such as scrappers and drill. The raw material can be classified into 4 types, namely chert, vein quartz, quartzite and volcanics, while only chert and vein quartz were major raw materials. This excavation further enriched the archaeological materials of the site and was also conducive to further improving the archaeological chronology sequence of the site.
