만경강 유역의 구석기 문화

The river system in Jeonbuk Province has a unique characteristic feature which is summarized as small and upper streams. The major rivers which crossed in the region are Gum River, and Seomjin River and its tributaries. However the middle and lower streams are all located on the outside of the region. Another rivers such as Mankyung River and Dongjin River which are entirely regional based, are generally small scale in their size. That means to say that all the river system in the region represent low-energy. A plausible hypothesis can be raised that their given environmental adaptional strategy is relatively identical to each other, if they belonged to the same cultural and/or chronological period of time. The people who lived around rivers had relatively similar environmental circumstances; easily get crossed so it did not necessary to follow the river all the way. Of these river basins, the Mankyung River Basin is mainly focused to be studied. In total,three Palaeolithic sites have been excavated: Bongkok, Jangdong and Sagueunri. They generate various types of Palaeolithic artefacts: from the simple flaked core tools to finely made blades and tanged points as well. They are usually come from the same cultural layers with a few exceptions. Even some of them are founded from multiple layers, the chronological difference is not widely distributed. That allows to tell that the all the varied cultural attributes are found in narrow chronological time span. With regard of the post depositional effect, the current preservation of artefacts is not perfectly in-situ. Some of them show an ideal sign of intact condition due the presence of high clustering distributional patterns and refitted artefacts. In spite of that, C-transform gave a severe negative effect on the artefacts preservation. It is highly due to not only the very recent construction but also early and middle 1900 s systematic river conservation works. Since that kind of works are mainly focused on the middle and lower river valley,Palaeolithic artefacts with mint conditions cannot be expected to recover in general senses.
