홍천 백이유적의 주먹대패 연구

Abstract

A rabot excavated from Baeki Site, Hongcheong County, is about 10cm. For this, some thick bodies with same length and width or longer ones were selected. The range of curved blade is from 1/4 to 2/5 and the retouched blade was bulged with saw teeth. For the body, broken stone at least one of which planes is flat was used and a bulged blade with long blade and a bulged blade with saw teeth were preferred. The bottom with a blade is divided into a flat stone and a ply and more than 3/4 thick of the body is separated in long direction and 1/4 was retouched six or ten times to make a rabot blade. For size of chopper and plane, the chopper is longer and wider, but the plane is thicker. Most of the chopper is retouched with an angle below 80˚, but the plane was retouched in right angle or obtuse angle. The choppers have straight blade or saw teeth blade, and the retouch range of curved blade is smaller than that of circumferential length. Choppers are made of round gravels and planes are made of broken gravels, which indicates that there is a difference in preference of shapes. The blades of both two stone devices were separated in long direction. The blade types of two devices were very different as follows: chopper was straight saw teeth and blade of plane was bulged saw teeth. The planes here were mainly made of quartz and quartzite compared to those of other sites. The mean of length and width was between 0.9 and 1.2. Remains in Songduri and Baeki are longer instead of being wider, and the length index of those in Chonggok, Majeon, Gundong, Wondang, and Dosan was 1.1, longer instead of being wider. The mean width was 1.3 in Chonggok, Majeon, and Gundong, which is the same as that of Baeki, and weight is about 780g, similar to that of Dosan. The mean retouch angle of those in Chonggok, Dosan and Baeki was about 90˚ . Generally, it was confirmed that the planes in Baeki Site, Hongcheong County have many common things instead of having different aspects This study confirmed that choppers and planes have difference in properties as well as in shapes through measuring and property analyses, but as it did not deal with use-wear, its function could not be clearly identified.
