Abstract

The upper paleolithic in our country is divided into the early period of upper paleolithic and later period of upper paleolithic based on the appearance of the blade and the microblade and its boundary is known as the period around 25ka. In Suyanggae Loc. 6, which was investigated recently, 4 cultural layers from early period of upper paleolithic to later period of upper paleolithic, corresponded to 42~ 22ka were investigated, through which the data to be able to identify the aspect of change in the stone tool making technique were secured. Among them, the CL 3 and 4 are corresponded to the early period of upper paleolithic together with the CL 1 to 3 of Suyanggae Loc. 3. These cultural layers are the blade culture-based cultural layers and the blade making technique and the tanged point using that were made. Particularly, in the CL 3 of Loc. 6, it attracts the attention as the microblade cores, microblades, etc. were unearthed together with new type of culture such as stone engraved with lines including ‘Suyanggae stone ruler’ and ‘Face-engrave sculpture’, etc. The microblade cores unearthed in the CL 3 of Loc. 6 are not wedge type, which the core was adjusted, but show the simple aspect that the microblade was taken off utilizing original shape as is without repairing the core. For the microblade cores unearthed in the CL 2 and 3 of Loc. 3, the core was adjusted partly but no separate preparation work in the working face was made and was disposed after taking off microblade once or twice. These are the aspect showing difference from the standardized microblade core enearthed in the CL 2 of Loc. 6 and Loc. 1, which are corresponded to the later period of upper paleolithic. As such, the artifacts to the microblade making unearthed in the CL 3 of Loc 6 and Loc. 3 can be considered that they are showing the early period of microblade making.
