양구 고대리유적 출토 합인석부(蛤刃石斧)의 표면관찰

Abstract

This article is the result of analyzing the observable properties on the surface of the stone axe excavated from Yanggu Godaeri sits. The analyzed properties are the use of raw material, symmetry of plane shape and angle of blade. The raw material used in the production of Stone axe was used selectively by granite gneiss. This is due to the rock features of raw material of granite gneiss and appears to have been optionally used in the site to suit the characteristics of Stone Axe, which has functions as felling tools. In plane form symmetry, the head of the Stone axe, which corresponds to the opposite side of the blade, was observed. The asymmetrical form seen from the head of the Stone axe is completed at the stage of production and appears to be a form of pursuit of functionality rather than formative beauty. In other words, the difference in internal and external mass seen at the head of the Stone axe is a result of efficient use of force, along with the function of the Stone axe, which is mounted on the axe handle and causes circular motion. Stone axe blades are distributed between 54 and 79° and generally show a high angle of not less than 60°. Along with the angle of the day, the case of experimental archaeology and the analysis of Wood Identification conducted in the site were reviewed together. As a result, it can be estimated that Stone axe with an angle of 63° or more was used for logging of hard wood for the construction of dwellings, and Stone axe with an angle of 55° or less was used for logging or processing soft wood for processing wood and securing firewood.
