초록

The aim of this study is to understand the pattern of producing large flakes excavated on Imjin-Hantan River basin and relation between large flakes and large flake tools--tools made on large flakes--in terms of producing techniques. The large flakes, which can be utilized as blanks of large tools such as bifaces, have been excavated here and there on Imjin-Hantan River basin. Producing large flakes, stone knappers primarily employ cortex of quartzite raw material as striking platforms. They don't modify striking platforms of large cores before flaking large flakes, which they produce by utilizing anvil techniques and side blows as changing percussion direction. Principally interior platform angles of these large flakes are obtuse ones and bulbs are convex and prominent. Large flakes are chiefly produced on the first stage of reduction process. Ones whose width is longer than their length are produced more than those of which length is longer than their width. Comprehending the relation between large flakes and large flake tools in terms of producing techniques begins from whether they are length-long or width-long. Length-long large flakes are mainly produced for making large scrapers. When tools are made of length-long large flakes, parts retouched mostly are left and right edges. Furthermore, distal parts are retouched when making cleavers of the large flakes. Width-long large flakes are flaked to produce cleavers primarily. In this case, distal parts and left edges are retouched in the main. The techniques of making tools on large flakes let the stone knappers produce tools more easily than those of manufacturing tools from cobble raw material. They undertake a part of producing large tools on Imjin-Hantan River basin.
