Abstract

Choppers were excavated from 16 sites in the Mankyng River Basin. The score that can be analyzed through the report is 50 points. The average chopper is a chopping-tool with a weight of 761.7g using quartz-based pebbles. The Paleolithic sites of the Mankyung River Basin are formed and destroyed in four stages from after 45,000 years to around 14,000 years. No significant changes were observed in the properties of the choppers constituting each stage, such as manufacturing techniques, stone materials, and working blade configurations. However, in terms of chopper weight, the choppers of the Mankyung River Phase I, II, and IV weighed around 700g, but in the coldest period, the Mankyung River Phase III, between 25 and 20,000 years, they weighed more than 1.1kg, showing a clear difference from the Mankyung River PhaseI, II, and IV. The average weight of Sukpyeong in Boseong, where a large number of choppers were excavated, is around 700g. Less than 10% of choppers weighed more than 1.1 kg. Depending on the weight of the chopper, usage and target object can be estimated. A chopper weighing around 700g was used as a method of continuous hitting while holding it in one hand. The target object is an object that is obtained by inflicting continuous blows for the 'pounding' action. A chopper weighing more than 1.1 kg was held with both hands and was used as a way to deliver heavy, strong blows rather than continuous blows. The target object is an object acquired for the act of ‘chopping’ rather than the act of ‘pounding’.
